|Product Name:||Honeywell (C437F1060) Gas Pressure Limit Switch|
|Description:||Pressure or differential - pressure limit controls for Industrial gas systems.
SPST mercury switch,. Auto recycle.|
Use C437 for spst switching or C637 for spdt switching. Compensate for momentary surges in gas pressure with a restrictive orifice in inlet pressure channel on the models with pressure range of 1PSI to 10 PSI Resume operation by manually resetting when using lockout application models. 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.
