The model R-1 pressure transmitter has been optimally designed for the specific requirements of refrigeration and air-conditioning applications. 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).
Features
  • Wetted parts from stainless steel. 
  • Resistant to all common refrigerants. 
  • Special case design for the best possible condensation tightness. 
  • Private labelling possible.
