Low Pressure Switch - Low Range Series 20 Explosion Proof Differential Switch


Series 20


2.5 in wcd to 75 psid


Unit: UL (as an outlet box only), SIL

Based on the tried and true Static “O” Ring type pressure sensor, the Low-range Series 20 explosion-proof low-pressure differential pressure detector can be installed in an explosion-proof housing. This low-pressure detector system virtually eliminates friction and resultant wear while yielding excellent repeatability in hazardous environments. The durability of the low-pressure detector is further ensured through rigid quality standards that are maintained from raw materials to finished products. High accuracy and repeatability for low-pressure differential pressure applications such as filter performance, dryer monitoring, and purge maintenance.

  • High repeatability
  • Narrow dead band
  • Field adjustable with no special tools required
  • SIL-2 listed for S.I.S applications
