Description
The pressure switches have been developed especially for safety-critical applications with limited space.
The high quality of the products and manufacturing in accordance with ISO 9001 ensure reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.
The robust switch enclosure from aluminium alloy or stainless steel 316L can withstand the rough and corrosive operating conditions of the process industry with working ranges of up to 1,000 bar. The access to the terminal block for the electrical connection is protected by a screw-on lid, which is secured with a screw-type lock against unauthorised intervention.
Special features
- No power supply needed for switching of electrical loads
- Robust switch enclosure from aluminium alloy or stainless steel with identical dimensions, IP66, NEMA 4X
- Setting ranges from 0.2 ... 1.2 to 200 ... 1,000 bar, vacuum ranges
- Repeatability of the set point ≤ 1 % of span
- 1 set point, SPDT or DPDT, high switching power up to AC 250 V, 15 A
