26 SPR01 REFRIGERANT PRESSURE SENSOR Description Technical Specification
SPR01 Pressure Sensor will measure refrigerant Pressure, especially R134(a). It uses flush ceramic piezo-resistive Technology. The advanced circuit design minimizes the impact of temperature and Humidity. Its pressure chamber is made of 316L stainless steel welted with O-rings to give trouble free leakage. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are installed inside the transmitter and the transmitter is featured with strong interference resistance.
