These high-quality differential pressure switches have been developed especially for safety-critical applications. The high quality of the products ensures reliable monitoring of your plant. The manufacturer Cella is certified to ISO 9001.
In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. All wetted parts materials are from stainless steel as standard. Each switch family is available in IP 65, Ex-ia or Ex-d versions.
In order to ensure as flexible operation as possible, the pressure switches are equipped with micro switches, which make it possible to switch 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 gold-plated contacts can be selected as an option. By using a diaphragm measuring cell with fulcrum lever transmission, the model DA10 pressure switch is extremely robust and guarantees optimal operating characteristics.
