Usage and ordering instructions:

Pressure regulation method:
When adjusting the PD-H-L1 type, the locking nut should be loosened counterclockwise first, and the pressure regulating screw should be rotated clockwise to increase the pressure to the given value displayed on the pressure gauge. Then, the pressure regulating screw should be rotated counterclockwise to activate the micro switch. The indicator light is on, gently tighten the lock nut, repeat fine adjustment until the signal is correct, and lock the lock nut.

The PD-H-L2 pressure regulating method is the same as above. The upper limit regulating screw is located near the label, and the lower limit should be adjusted first, followed by the upper limit.
The working environment should not contain corrosive gases.
Please specify the name, model, voltage regulation range, and working power supply when placing an order.

[pressure relay]DP-63(A)B type pressure relay

2026-6-13 19:15:07

DP-63 (A) B-type pressure relay is an automatic switch component with isolation function, widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment, and is one of the most important control components.
....
Relays generally have sensing mechanisms (input parts) that can reflect certain input variables such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc; There is an executing mechanism (output part) that can achieve "on" and "off" control of the controlled circuit; Between the input and output parts of the relay, there is an intermediate mechanism (driving part) that couples and isolates the input quantity, performs functional processing, and drives the output part.
