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 an isolation membrane filled hydraulic resistance pressure sensor at the front end. It is converted from high-precision A/D, processed by a microprocessor, displayed on site, and outputs four analog signals and two switch 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

2、 Characteristics

◆ 4-digit LED digital display, ignoring value errors

◆ Five control point relay output 220V 3A

◆ 4-20mA standard signal output (optional)

On site setting of control points.

◆ Power supply optional 24VDC 220VAC

3、 Technical parameters

4External dimensions

5.1 Mechanical Connection:

This product can be directly installed on hydraulic pipelines through pressure pipe fittings (M20 * 1.5) (other sizes of fittings can be specified when ordering). In critical applications such as severe vibrations or impacts, 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:

● Try to keep the line connection as short as possible

● Use shielded wire

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

If a micro hose is used for installation, the housing must be separately grounded

6、 Set Function

. 1 Output

This product has five switch outputs. The corresponding output will be at the switch point

Switch when the suction value reaches and reply when the pressure drops below the release value.
