DESCRIBE

ETD-200 pressure switch can sense small pressure changes for switching action. This type of pressure switch is widely used for monitoring the flow control filter, blower and air regulating valve of ventilation system; It is also suitable for heating coil overheating protection and industrial cooling circuit frosting protection. The product is visual and adjustable, and can intuitively adjust the action value of the pressure switch. ETD-200 is an adjustable pipe differential pressure switch and a wind differential pressure switch used by the residual pressure controller for building fire protection. The mature design enables it to detect small pressure changes. The switch set point or switching point can be adjusted in the field by simply using the adjustment knob and the built-in calibration visual scale. This switch is equipped with a transparent cover, which not only protects the adjustment knob scale change, but also provides IP54 protection.
