  Description
  These high-quality and robust temperature switches have been developed especially for safety-critical applications.The high quality and the manufacturing of the product ensures reliable monitoring of your plant. The manufacturer,Cella, is certified to ISO 9001. In production, the switch is monitored, step by step, through quality control software, and is subsequently 100 % tested.
  All wetted parts materials are from stainless steel. Each switch family is available in IP 65, Ex-ia or Ex-d versions.

  In order to ensure as flexible operation as possible, the temperature switches are fitted with micro switches, which enable the switching of an electrical load of up to 15 A/AC 220 V directly. For smaller contact ratings, such as for PLC applications, Argon gas-filled micro switches with goldplated contacts can be selected as an option.

  With its flexible AISI 316 spiral protection hose, the model TCA temperature switch is extremely robust and guarantees optimal operating characteristics for applications requiring particularly high corrosion protection.
