GE511 Adjustable Differential Pressure Switches

Product Description

The Differential Pressure Switch is a new type flow switch, when the water flow (differential pressure) in system rises up or falls down to one set value, it will output a warning or sent switch-off signal to automatic control system. And it could also be used to indicate the status of pump or water filter.

It could avoid the shortcomings of annual inspection or changing target flow switch for water chiller unit so it could be applied widely in the water protection, status feedback of pump and by-pass control of differential pressure in evaporator and condenser in medium and large sized water chiller unit.

Product Specification / Models

GE-511A Series is D-P Flow Switch with single adjustable setpoint. The adjustable differential pressure switch could be calibrated directly by manufacturer according to customer's requirement, and printed the calibrated value on the label of product, so user needs not readjust in the field. The customer could calibrate by professional instrument according to the differential pressure required by equipment, and A.YITE COMPANY could provide relevant service.

GE-511B Series is D-P Flow Switch with 2 adjustable setpoint. In order to meet various requirements of customers, A.YITE COMPANY also developed the adjustable double setpoints DP switch for upper-lower limit control of differential pressure. And if choose the local indicator, it could be applied to control the water cooled evaporator and condenser in HVAC system, the more or less flow of other heat exchanger, and low flow of heat exchanger due to scaling or dirty jamming, which has incomparable advantages than target flow switch.
