The WIKA R-1 pressure transmitter is designed for the requirements of refrigeration and HVAC applications. The all-welded stainless steel design eliminates the need for seals on the process connection. This qualifies the R-1 for use with all typical refrigerants, the company says. The hermetically-welded, dry, thin-film measuring cell provides long-term leak resistance. In addition, the sputtered stainless steel measuring cell features high long-term stability, along with an extremely high burst pressure.
