1、 Overview
This series of pressure controllers 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 a front end equipped with an isolation membrane filled oil pressure resistance pressure sensor. It is converted by high-precision A/D, processed by a microprocessor, displayed on site, and outputs four analog signals and two switching signals.
This intelligent digital pressure transmitter 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., for on-site measurement, display, and control of fluid medium pressure

◆ 4-20mA standard signal output (optional)
Control point on-site setting.
◆ Optional 24VDC 220VAC power supply
3、 Technical parameters

4、 Overall dimensions

5.1 Mechanical connection:
This product can be directly installed on the hydraulic pipeline through a pressure pipe joint (M20 * 1.5) (other sizes of joints can be specified when ordering). In critical applications such as severe vibration or impact, pressure pipe joints can be mechanically decoupled through micro hoses.
Note: When the range is less than 100KPa, it must be installed vertically
5.2 Electrical connections

To prevent the impact of electromagnetic interference, the following precautions should be taken:
● Keep the line connection as short as possible
● Using shielded wires
Try to avoid directly approaching the wiring of user devices or electrical and electronic devices that cause interference as much as possible
If micro hoses are used for installation, the casing must be separately grounded
6、 Setting functions
. 1 Output
This product has five switching outputs. The corresponding output will be at the switching point
Switch when the suction value reaches and recover when the pressure drops below the release value.
6.2 Setting Switch Points

AL1H is the pull-in value of switch 1, AL1L is the release value of switch 1
AL2H is the pull-in value of switch 2, AL2L is the release value of switch 2
AL3H is the pull-in value of switch 3, AL3L is the release value of switch 3
AL4H is the pull-in value of switch 4, AL4L is the release value of switch 4
AL5H is the pull-in value of switch 5, AL5L is the release value of switch 5
