PRESSURE TRANSDUCERS
2Pages

The new range of pressure transducers are designed to offer a highly accurate and stable piezoresistive pressure capsule, within a low cost OEM package. Whilst they can be used in various applications, the most common applications are environments that require the pressure of refrigerant gas to be monitored. The transducers transmit a 0-10V or 4 20mA output signal to a controller or monitor, and are available in the following formats: The pressure transducers are mounted by means of a 7/16֔ 20UNF female thread (ּ female flare), and secured by a 17mm a/f hex section. The electrical connections are screw terminals located within a square detachable mPm-193 connector and gland assembly. -1 to +14 bar, Suction line (SF0300 & SF0302) -1 to +34 bar, Discharge line (SF0301 & SF0303) > Product Type SF0300 & SF0302 & SF0301 SF0303 Signal Output 4-20mA 0-10Vdc Configuration 2 wire + Earth3 wire + Earth > Supply Voltage 8-28Vdc 13-30Vdc The external casing is a soldered steel construction, providing a highly stable measuring cell. The sensing element is suspended in an oil filled capsule to provide excellent shock and vibration performance. Similarly, any mounting torque effects are also eliminated.
