PS300 Electronic Pressure Switch

The electronic pressure switch is a pressure measurement switch with LED display. The isolation-based silicone oil-filled diaphragm is used as a sensing component. It has the advantages of high precision, small size, easy operation and simple installation. Therefore, it is widely used in pressure control and automatic process control systems in chemical, mechanical and electrical systems.

Application :

● Hydraulic pressure controller

● Industrial automation control

● Tank Liquid Level Control

● Petrochemical industry

● Water conservancy

● Automatic detection system

Advantages
01It uses isolation silicone oil-filled diaphragm as the sensing component with high accuracy.
022 channels switch output, load capacity of 1.2 A.
03Pressure interface can rotate 330 °, which is convenient to use.
04Equipped with node action leds, convenient for observation.
