1、 Overview

Electronic pressure switch is an intelligent digital pressure measurement and control product that integrates pressure measurement, display, output, and control. This product is a fully electronic structure, with an isolated diaphragm filled hydraulic resistance pressure sensor at the front end. The output signal is amplified and processed by a high-precision, low-temperature drift amplifier, and sent to a high-precisionA/DConverter converts digital signals that can be processed by microprocessors, and the processed signals control two switches to measure and control the pressure of the control system. This pressure switch is flexible to use, easy to operate, easy to debug, and safe and reliable. Widely used in industries such as hydropower, tap water, petroleum, chemical, mechanical, hydraulic, etc., to measure, display, and control the pressure of fluid media

4、 Installation

4.1Mechanical connection:

This product can be connected through a pressure pipe joint（DIN3582External threadM20*1.5）(Other sizes of connectors can be specified at the time of ordering), directly installed on the hydraulic pipeline. In critical applications such as severe vibrations or impacts, pressure pipe joints can be mechanically decoupled through micro hoses.

4.2Electrical connection:

To prevent the impact of electromagnetic interference, the following precautions should be taken:

Using shielded wires, if installed with micro hoses, the casing must be separately grounded

Try to avoid direct contact with user devices or wiring of electrical and electronic devices that may cause interference

、Setting functions

6.1Switching Output

This switch has1-2Road switch output. Each switch output can be set1A pressure switch point and an opening delay value.

The corresponding output will switch when the suction value of the switch point is reached and return when the pressure drops below the release value.

6.2Set switch points

AL1HThis value is the switch1Pull-in(When the pressure reaches this point, it will be pulled in and the indicator light will turn on)

AL1LThis value is the switch1Release value (when the pressure reaches this point, it will disconnect and the indicator light will turn off)

AL1DThis value is the switch1Action delay (the number of seconds that must be waited before switching)

AL2HThis value is the switch2Pull-in(When the pressure reaches this point, it will be pulled in and the indicator light will turn on

AL2LThis value is the switch2Release value (when the pressure reaches this point, it will disconnect and the indicator light will turn off)

AL2DThis value is the switch2Action delay (the number of seconds that must be waited before switching)
