OEM pressure transmitter is ideal for refrigeration and cooling systems

A new stainless steel welded pressure transmitter for refrigeration, chillers and air conditioning systems is now available from instrumentation specialist Impress Sensors & Systems Ltd.

The new 17.609 G welded pressure transmitter has a stainless steel housing, pressure port and diaphragm and requires no O-ring seals. The transmitters can operate in temperatures from -40 deg C to + 125 deg C, making them ideal for OEM pump and compressor applications within refrigeration, chillers, air conditioning and other process cooling systems.

Sam Drury, Sales & Marketing Director at Impress Sensors & Systems comments: “Refrigeration plants use gas, liquid and mechanical energy to move heat from one place to another. Compressors and pumps are required to repressurise the gas, and discharge the liquid through cold water heat exchangers or cooling fans.”

“The refrigeration media, normally R134a in Europe, is mixed with an oil or lubricant, of which there are many different types. This is to ensure that the refrigerant can be transported easily through the pipework. However, when it comes to selecting a pressure transmitter for the pumps or compressors within these systems, it is very difficult to achieve compatibility between the refrigeration media [oil or lubricant] and the O-ring seals on the pressure transmitter. The 17.609 G is ideal for these types of applications, as it operates oil-free and is welded so it requires no O-rings.”

The pressure transmitter is available in compound nominal pressure ranges from 0… 6 bar up to 0… 60 bar and from –1… 6 bar up to –1… 60 bar. This means the sensors can measure pressures in a vacuum, as well as being resistant to vacuum conditions. The sensors also offer up to three times overpressure or higher.

The pressure transmitters are designed to withstand the vibration and shock levels normally associated with pump and compressor applications. The sensors are also supplied with a ¼-inch flare connection, the industry standard for refrigeration applications.

Standard output is 2-wire, 4…20mA, with optional 3-wire, 0…10V or 3-wire ratiometric also available.
