Write a review

$321.18

The digital fluid pressure control switch integrates pressure measurement, display, output, and control in one device. A silicon piezoresistive sensor provides the pressure signal, followed by low-drift amplification and high-resolution A/D conversion for accurate digital processing. Real-time pressure display, two switch outputs, and a 4–20 mA analog output enable reliable pressure monitoring and control across a wide range of 10 kPa to 100 MPa.

Tips: How to protect the digital fluid pressure control switch from pressure spikes and hydraulic shock?

In systems with pulsation, hammering, or sudden pressure surges, it is recommended to install a pressure snubber, damping orifice, or throttle restrictor at the sensor of the pressure switch’s inlet. These components suppress instantaneous spikes, stabilize the pressure waveform, and significantly reduce impact on the sensing diaphragm. For severe hydraulic shock, a buffered tee joint or capillary tube can also be used to enhance protection.
