Description
In order to ensure as flexible operation as possible, the absolute pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected. All wetted materials are from stainless steel as a standard. By using a diaphragm measuring system, the model APA absolute pressure switch is extremely robust and guarantees optimal operating characteristics and the highest measuring performances, with repeatability lower than 1 % of span.
