Ultrasonic Sensors from Pepperl + Fuchs

Ultrasonic sensors from Pepperl + Fuchs present the ideal solution for non-contact position and distance measurement in all industrial areas where environmental conditions such as dust, smoke or steam may affect the sensors. Objects consisting of a variety of materials can be detected to within millimeters regardless of color or shape.

The ultrasonic sensor produces a data carrier utilizing very high frequencies that are outside the human’s audible range. The time it takes for that ultrasonic wave to pass between the sensor and the object is the value for the distance or the position.

Ultrasonic sensors have proven their reliability and precision in many industries and applications, including:

  • lumber and furniture
  • construction materials and equipment
  • farming equipment
  • level control applications

Ultrasonic Sensor Q&A with Pepperl+Fuchs

Here are some questions and answers that were recently featured in a Pepperl+Fuchs blog post:

Q. I work in a manufacturing plant. I need a sensor to monitor the height of our product in order to sort out any imperfections. The sensor must allow slight variances in height but detect if it is too tall or too short. What are my options?

A. This application would be best solved with an ultrasonic sensor in window mode. Window mode allows you to set the beginning and ending points of an active sensing window. This is accomplished by teaching the sensor a near point and far point in which the output will be triggered between these two points. Any objects within this range will be accepted, but any that fall below the near point or stretch beyond the far point will be sorted out.

Q. I need a sensor to control a pump. When the liquid reaches the high level, the pump would be switched off. Once the liquid level goes below the minimum, the pump would be switched on. Can I do this with an ultrasonic sensor?

A. An ultrasonic sensor in hysteresis mode is commonly used for pump control applications. In hysteresis mode, the evaluation window is limited by two switching points. These two switch points are programmed for the high and low level of the liquid. The pump turns on at the low level, and off at the high level. This allows the pump to be on until the high level is reached and then turned off at the low level. The two switch points create an adjustable hysteresis window.

Measurement Displacement Sensors

My friends from Pepperl + Fuchs shared this information regarding measurement displacement sensors and I'd like to share it with you:

Measurement displacement sensors are used when you need to know a continuous distance that the sensor is from a selected target. There are two primary output types that can give distance.  The discrete digital output is basically a yes or no signal threshold that will change the output of the sensor when the target reaches a certain distance or falls within a certain range.
An analog output will give a continuous analog signal either on 4 mA to 20 mA or 0 V to 10 V (model dependent). This signal is established by teaching in a window on the sensor that will have the near or far limit return 4 mA or 20 mA. This information is then interpreted by a controller or PLC to give you a distance measurement.

The VDM28 Series is a popular distance measurement photoelectric sensor that is relatively low cost for the range and performance it yields. The VDM28 Series has a diffuse sensing range of 8 meters or about 26 feet. The long sensing distance and small light spot diameter is possible through the class 1 or 2 laser (model dependent) that the sensor utilizes. The long range and exceptional accuracy are all due to to pulse ranging technology.

The sensor sends out a short pulse of light, and that light is reflected off the target. The time it takes for the light pulse to reach the sensor's receiver is used to calculate the target's distance. This method is more effective than phase correlation, which is more susceptible to ambient light due to continuously sending out light and evaluating the slight phase change. Some models of the VDM28 Series of lasers also offer dual, independent discrete outputs for applications where switch outputs are needed rather than a continuous distance measurement.

The photoelectric VDM18 Series is offered for more precise applications requiring a very high resolution at a shorter sensing range. The two primary models have a 100 mm range and a 300 mm range, both with exceptional resolution for applications demanding better than 1 mm accuracy. Since this sensor is based on a triangulation method of distance measurement, both VDM18 models have a better resolution than the VDM28, but this unit is also more costly (usually more than double the price of the VDM28).

Ultrasonic sensors are another common sensing method. Pepperl+Fuchs has several models available. Most come with either switching outputs or analog outputs. They can be used for detection based on a window, threshold value, or they can be used for continuous distance measurement using the analog output. Most UC Series ultrasonic sensors offer a 0 to 10 voltage output and a 4 to 20 mA output signal. There are also discrete signal models. The advantages offered by an ultrasonic sensor are in the function of operation. Since ultrasonic sensors operate by transmitting sound waves instead of a light source, they are not sensitive to targets that have different colors and are a good option for detecting transparent objects. This is critical for tank filling applications when the fluid is transparent such as water or where the use of a laser light source is not possible.

Some successful applications include overhead crane operations, level measurement, or direct distance measurement of targets when accuracy is critical. The tank measuring application described earlier involves using an ultrasonic sensor to determine the level in the tank. If the distance is known, you can derive a formula to find the relationship between the distance, and how full the tank is. Continuous measurement will require an analog output (0 V to 10 V or 4 mA to 20 mA). If continuous measurement is not important, a discrete output model can be used. For example, many tank level applications just need a high and a low point to trigger a pump to turn on or off.  In these applications, a discrete output model is preferred.

Let Me Tell You How I conquered custom application

Resolving a customers issue/concern. This is he result of working with a customer on an application that they were looking to automate. We went in and reviewed the application with the customer to see what we could offer, we asked a lot of questions and got to see the equipment up close and personal (sorry a movie pun). By working with the customer and communicating all the issues / concerns they had we were able to come back with a solution that is cost effective and will work well for them going forward.

Project 2 – Glue Pot Auto Fill System:

Looking again for us to design a solution for him that would consist of a pump, motor that would allow him to keep his 55 gallon drum at a consistent level so the operator would not need to check the levels in the drum. It is a typical glue pot system according to the customer @ “XYZ”. They would like a indicator, and again to keep the depth of the glue consistent. Let me know if this is a project that Marshall Wolf would be interested in. I can set up a time to meet with the customer if you feel either or both of these projects are of interest.

Solution Presented to Customer:

Operational Specs:

Ultrasonic Sensor (below) will monitor the tank level. When tank level; hits the low limit the sensor will actuate the SPDT relay. Relay will control actuation of the valve. The valve will allow glue to flow into the tank; end user (Nosco) is responsible for the installation of the valve. Valve will be wired to “NO” contact on the relay. Relays contact rating is = 10A (1540VA resistive / 990VA inductive)

Secondary option:

Valve can be wired to a male or female M12 cable; this would make the system a plug and play solution.

 

BOM to include the following parts: Left out as it is a custom application, parts incluede an Ultrasonic Sensor, Power Supply, Relay and Socket and an Enclosure

Please let us know if you are having similiar projects, we would like the opportunity to come in and review possible solutions with you.

 

Carlo Gavazzi Level Sensors

Carlo Gavazzi's comprehensive range of level detection products is well suited to solve most level control applications. Their range is able to detect conductive and non-conductive liquids, granulates, grains, and plastics.

We offer level sensors and level control relays for both on/off control and continuous monitoring of levels. We offer conductive probes and amplifiers, capacitive level sensors, ultrasonic sensors, magnetic level probes, and optical sensors.

Typical applications are for level control in wells and municipal water systems, protection of pumps, levels in grain elevators and feed conveyors, and level detection in vacuum delivery systems in the plastics industry.

The multi-function CLD/P controllers allow easy monitoring of two to four level points, with simple selection of functions, including filling, emptying, and a tank-well option, which allows a single device to control levels in an above ground tank and underground well, and prevent either from running dry.

A master-slave option allows up to seven controllers to be directly connected to each other. A new single-point controller is added to the family, which includes a time delay function to allow for filling or emptying of a tank with a single level point.

All functions and adjustments of the CLD/P Series are made via rotary switches and potentiometers on the face of the unit – no dip switches or push buttons are used. LEDs on the controllers give clear indication of the power and relay output states. The controllers are in compact 17.5 or 35mm wide housings, with DIN-rail mount or eleven pin plug connection.

The CLD/P Series are UL, cRus and CSA approved, and designed to be in compliance with all relevant European and North American standards, and carry the CE mark.  Contact Marshall Wolf Automation for all of your sensor needs!

Do You Need To Measure Fill Levels In Small Containers?

The self-contained Pepperl+Fuchs F65 ultrasonic sensor is a ready-to-connect, complete device.

This series is ideal for small container fill level applications because of its low-profile housing. The ultrasonic transducer is slightly recessed in the housing for protection and has an integrated gasket that enables an airtight seal.

These ultrasonic sensors have two fully adjustable switching outputs (S min and S max) which can each be assigned a range. This allows you to measure both the minimum level and maximum level in the tank.

The values are set on the 3RX4000-PF programming unit using the SONPROG software package or a potentiometer. Again, this series is ideal for ultrasonic level control. 

Marshall Wolf Automation is your authorized Pepperl+Fuchs distributor for their complete line of inductive and capacitive proximity sensors, photoelectric light sensors, ultrasonic sensors, intrinsically safe barriers and much more.
