HONEYWELL C437F1045 Pressure Switch, Auto recycle, 1 - 26 in. wc
[C437F1045]
$301.22


HONEYWELL C437F1045 Pressure Switch, Auto recycle, 1 in. wc to 26 in. wc. Pressure or differential pressure limit controls for industrial gas systems.


Features:

Uses C437 for SPDT Mercury switching.

Compensate for momentary surges in gas pressure with a restrictive orifice in inlet pressure channel on the models with pressure range of 1 to 26 in. wc (0.25 to 6.5 kPa).

Impede tampering and provide dust-resistant operation with enclosed setting.

Increase strength of control diaphragm with Buna-N fiber-reinforced material.

Clear glass cover allows observation of interior mechanism to aid in setting and checkout.

Mercury switch provides visual indication of switch position.
