1overview

This series of pressure transmission 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 isolated membrane filled hydraulic resistance pressure sensor, which is composed of high-precisionA/DConversion, processed by microprocessor, displayed on site, and outputting one analog signal and five switch signals.

This pressure controller 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

5、 Installation

5.1Mechanical connection:

This product can be connected through a pressure pipe joint(M20*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.

5.2Electrical connection

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

The line connection should be as short as possible and shielded wires should be used

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
