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.
