Description

The WIKA R-1 pressure transmitter is engineered for demanding HVAC and refrigeration service where leak tightness and durability are critical. Its high-accuracy measuring cell is welded directly to the process connection to eliminate elastomer seals and support dependable operation with common refrigerants, while stainless steel wetted parts provide robust media resistance. The design is maintenance-free and field proven for very high load cycling, and the special case design supports stable performance even in harsh ambient conditions and condensation prone environments. Each item is supplied with a 4 to 20 mA two-wire output and 7 to 30 V DC power supply for easy integration into industrial control systems. This item is configured for -1 ... +20 Bar Gauge measurement, uses 7/16-20UNF-2B Schrader Female Connection, and includes a 5m flying lead cable with IP69K connection and cULus approval.
