The R-1 pressure transmitter from WIKA is designed for the special requirements of refrigeration and HVAC applications. The all stainless steel measuring cell eliminates the need for soft sealing materials between the sensor and process connection.
The R-1 provides a linear amplified output with short circuit, reverse polarity and overvoltage protection. The hermetically welded, dry, thin-film measuring cell provides long-term leak resistance. In addition, the sputtered stainless steel measuring cell features excellent long-term stability and an extremely high burst pressure.
