This Adjustable Differential pressure switches adopt stainless steel material, dirt resistant, sterile, sanitary. This differential pressure switch offers a large adjustable pressure range for the pressure setpoint, from 1psi to 43.5psi. It adopt precision snap-acting switch and sensitive diaphragms combine to provide a narrow deadband and one-percent span repeatability.
Specification:
* Max Voltage 250V, Max Current 3A
* Output: Single SPDT Switch
* Connection: G1/4" Female or NPT1/4"
*Material: SS304 SS316L or Brass
* Max Static Pressure: 20bar
* Repeatability: 1% Span
* Accuracy: 0.001Mpa
* Easy External Adjustment
* NEMA 4 Enclosure, Watertight Conduit Connector
The Differential Pressure Switch is a new type pressure and flow monitor 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.

GE-511B Series is Differential Pressure 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.
