規格介紹:WIKA MW
Diaphragm pressure switch
詳細介紹:
These high-quality diaphragm pressure switches have been developed especially for safety-critical applications. The great advantage of diaphragm pressure switches is that no supply voltage is required for the switching process.
Features:
- • Case from 316L, IP66, NEMA 4X
- • Setting ranges from 16 mbar to 600 bar, also all other equivalent vacuum or combined pressure and
- vacuum ranges
- • Intrinsic safety Ex ia available
- • 1 or 2 independent switch points, high switching power up to AC 250 V, 20 A
- • Switch point repeatability < 1 %
