Blast resistant Series H3 Explosion-Proof Differential Pressure Switch, rock solid, modern unit has an exceptional new plan which gives aversion to differential tensions as low as 10 creeps of water (254 mm w.c.), yet handles all out strain of 1500 psi (103 bar).

Series H3 Explosion-Proof Differential Pressure Switches
Setpoints from 10″ w.c. to 200 psid – Rated 1500 psig, Weatherproof

Dissimilar to normal differential strain switches that utilization a cylinder type movement move, the Series H3 uses a rotating movement move shaft that keeps an adjustment of complete tension from causing a setpoint shift. Unit yields deadbands around 5% of reach, with zero setpoint shift because of variety in working tensions. Rubbing is limited and repeatability expanded by permitting range spring to act straightforwardly on stomach plate. Moving stomach configuration keeps up with steady compelling region to additionally lessen grinding. Stomach is permitted to “seat”, permitting use of full appraised pressure, up to 1500 psi (103 bar), on one or the other high or low strain port, without harm. Extraordinary over-travel include forestalls overtightening of reach change screw.

Product Applications :
* Water flow proving with an orifice plate.
* Differential pressure across chiller.
* Liquid filter status.
* Perfect for monitoring differential water pressure on filters, chiller coils, and flow elements.

Features :
* Rotary motion design prevents set point shifts
* Explosion-proof housing for use in applications where protection of process and personnel is needed
* Option for use with water and water-based solution makes this a versatile switch
