Temperature Control Products

Power-supply manufacturer Carlo Gavazzi recently released a series of switching devices the company deems "economically friendly," the RMD Hybrid Relays. The product provides mercury-free switching, designed for controlling heating elements inside of food ovens, warmers, fryers, rotisseries and other food equipment. It's capable of switching up to 20 cycles per minute, with a 4 million electrical cycle life expectancy.

The RMD Series combines solid-state technology and electromechanical relays to provide a hybrid relay. This means that there is virtually no contact arcing, which  results in prolonged relay life and much less emission inside of the panel. Another benefit of hybrid technology is a full amperage rating at elevated operational temperatures. While most conventional switching devices are rated at 25-40 degrees Celsius, the RMD Hybrid Relays are fully rated up to 60 degrees Celsius. The RMD3H switches heaters on three legs while the RMD2H is a lower-cost alternative, as it switches two poles and the third pole is directly connected between L2 and T2. Additional technical features include:

• Two- (for single and three phase circuits) and three-pole arrangements
• Rated for 4 million electrical cycles
• Rated for up to 20 cycles per minute
• Two output voltage ratings: 240VAC (VL-L) and 277VAC (VL-N – 480VAC with Neutral)
• Three common control voltages: 24VAC, 120VAC, 240VAC
• Two amperage ratings: 30A up to 70 degrees Celsius, 40A up to 60 degrees Celsius
• Similar mounting to Mercury Displacement Contactors
• Mercury-free, RoHS compliant, cRUus recognized

P+F is a great source for all types of ultrasonic sensors, including ultrasonic motion sensors and ultrasonic range sensors.  Ultrasonic sensors 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, including lumber and furniture, construction materials and equipment, farming equipment and in level control applications.

Pepperl+Fuchs’ ultrasonic sensors currently encompass twelve series of mechanical designs for through-beam, direct detection and retro-reflective operation. Customer and application specific custom solutions underscore our technological competence in this area of sensors.

Some product features are:

• Devices with TEACH-IN functionality for fast and simple installation
• ULTRA 3000 software for improved adaptation of sensors to applications
• Adjustable sensitivity to the sound beam width for optimized adjustment of the sensor characteristics according to the application
• Temperature compensation - compensates for sound velocity due to varying air temperatures
• Synchronization input to prevent cross-talk interference when sensors are mounted within close proximity of eachother
• Sensors with digital and/ or analog outputs

Are you looking for products that are environmentally friendly?

Our Carlo Gavazzi RMD hybrid relays, just released last summer, would help you reach that goal!

The Carlo Gavazzi RMD series provides a mercury-free switching solution which is ideal for controlling heating elements inside of food ovens, warmers, fryers, rotisseries and other food equipment.

They are not many items on the market which are capable of switching up to 20 cycles per minute, with a 4 million electrical cycle life expectancy!

The Carlo Gavazzi RMD Series combines the benefits of solid state and electromechanical technology and provides a hybrid relay.

This means that there is virtually no contact arcing, which results in prolonged relay life and much less emissions inside of the panel. Another benefit of hybrid technology is a full amperage rating at elevated operational temperatures.

While most conventional switching devices are rated at 25°C or 40°C, the Carlo Gavazzi RMD relays are fully rated up to 60°C.

The RMD3H switches heaters on three legs while the RMD2H is a lower cost alternative, as it switches two poles and the third pole is directly connected between L2 and T2.

Crouzet Millenium Application #2:
Water Treatment

Do you own a pool, manufacture swimming pools or service pools? This application is going to focus on controlling water quality in a swimming pool.

As a pool owner, manufacturer or user you need to:

• Control physical filtration of water
• Set fitering time in relation to the temperature of bathing water
• Control the pH of the water
• Control the level of water disinfection

Using the Crouzet Millenium 3 XD10 24VDC logic controller, pH probe, ORP (Redox probe) and Pt100 probe, plus an application specific analog extension you can do the following.

Water needs to be filtered regularly to keep it clear. The higher the temperature the longer this takes.

Both pH and Redox are measured using probes submerged in pipes, a container or an analysis chamber. These probes will analyze the presence of hydrogen and chlorine ions capable of oxidizing an electrochemical couple with the probe.

This oxidation generates an electrical voltage, expressed in mV, which is forwarded to the PLC. After a calibration process the PLC converts this into values for the pH and Redox.

Additional Crouzet Millenium 3 functions are available for other requirements including lighting control, vacuum pumps for the pool cleaning brushes and more!

Crouzet Millenium Application #1:
Heat Pumps

Make the most of natural energy - air, water - to heat or cool a hot water system or heating circuit.

Using a Millenium 3 logic controller and NTC and Pt100 accessories you can do the following:

The heat from the warm fluid is captured by a refrigerating liquid which is compressed to give it a pressure of 40 bar and a temperature of 140°.

In a heat exchanger, this refrigerating liquid then transfers its heat to water for a hot water system or a hot water tank.

Once this thermal exchange has taken place the fluid, which has lost both temperature and pressure, has its pressure further reduced by a solenoid valve which drastically reduces its temperature even more.

This fluid is then able to receive the heat from the hot source and the cycle is ready to begin again!

I was looking through our latest Crouzet catalog and came across a great section describing logic controllers.

Basically it gives a simple description of what a logic controller is. Marshall Wolf Automation carries the IDEC SmartRelays and Crouzet Millenium programmable logic relays.

'A logic controller is a programmable module which is used to control small automation systems or small installations.

The logic controller is a plural solution in a control system since it contains solutions that can replace a number of products; timers, counters, control relays, temperature controllers, impulse relays, etc.

The logic controller operates as the brain of applications. It is capable of retrieving information and triggering actions; it can be adapted to suit the needs of customer applications.'

Actions that a Crouzet Millenium or IDEC Smart Relay logic controller can handle are controlling, measuring, managing and communicating.
