C437D1013 Pressure or differential - pressure limit controls for industrial gas systems. SPST merc switch, opens circuit on pressure rise manual reset. 1/2 to 5 PSI, Max Sustained Operating Pressure 15.0 PSI
|Product Name:||Honeywell Gas Pressure Limit Switch|
|Description:||Pressure or differential - pressure limit controls for industrial gas systems. SPST mercury switch, opens circuit on pressure rise manual reset. 1/2 to 5 PSI.
Maximum sustained operating pressure 15.0 PSI|
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 1/2 to 5 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.
