GE-511A Differential Pressure Switches with Brass Body

GE-511A Brass body DP Controller is Pressure Differential Switch with 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

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.

Replace Common Target Paddle Flow Switches as Differential Pressure Type Flow Switches:

Till today, the target type flow switch still is popular, because the price is very low, but less user pay attention to the prevalence of the short lifetime of target flow switch. Admittedly, the lifetime only have 1-2 years, then the user have to change a new target flow switches.

  { The Failure and disadvantage of Target Type Flow Switches }

Most user have accepted this problem as ineluctability, but, it' s a wrong opinion. If the user choose our GE-511 series Differential Pressure type flow switches to replace the common target flow switch, the lifetime could achieve more than 10 years.
