Description

Application area in refrigeration and air-conditioningtechnology
The model R-1 pressure transmitter has been optimally designed for the specific requirements of refrigeration and air-conditioning technology. Its monolithic construction dispenses with the need to use seals on the process side. This enables the model R-1 to be used with all typical refrigerants (e.g. Freon and Ammonia).

Excellent reliability
The hermetically-welded, dry, thin-film cell ensures long-term leak tightness. Moreover, these efficient cells, made with a sputtering technique, feature high long-term stability and a very high burst pressure.

Attractive price/performance ratio
The production on highly-flexible production lines, also offers a very attractive price-performance ratio with higher quantities.
