D400 & D700 ASHCROFT

Snap Action Switches

for Low Range Differential Pressure Control

INTRODUCTION

The Ashcroft differential pressure switch is a precision built con-

trol device which features a mechanical snap action switch.

Controllers are available for operation on various pressure differ-

entials with fixed or variable switching differentials. Also, manual

reset types are available for operation on increasing or decreas-

ing pressure.The manual reset types remain trlpped until reset

by pressing a button on the top of the enclosure.The standard

electrical switch Is SPDT and is available with various electrical

characteristics.Two SPDT switch elements mounted together

are available except on variable deadband and manual reset

types.Various wetted material constructions for compatibility

with a wide r

ange of pressure media ma

ybe obtained.

The Ashcroft snap action differentiaI pressure switch is fur

nished in the standard NEMA 4 and explosion proof NEMA 7

and 9 enclosure styles

Both enclosures are epo

xy coated
