The R-1 pressure transmitter is designed for HVACR applications. The all-welded stainless steel measuring cell eliminates the need for soft sealing materials between the sensor and process connection. This qualifies the R-1 for use with all typical refrigerants including chlorofluorocarbons R-12, R-22, R-123, R-134a, and ammonia. According to the manufacturer, the pressure transmitter is condensation-proof. The sputtered stainless steel measuring cell features high long-term stability, along with an especially high burst pressure.
