Chaohui N70 pressure measuring instrument

Product Overview

The N80 intelligent digital pressure gauge is a new product developed by our company, which integrates multiple advanced international electronic technologies, single-chip computer technology, electrical erasing technology, anti-interference technology, etc., ensuring that the instrument has high measurement and control accuracy, strong anti-interference performance, and other advantages. The whole machine adopts a 96 × 96 × 100 (N70)/48 × 96 × 100 (N80)/96 × 48 × 100 (N90) shell, which has the advantages of small size, light weight, low power consumption, complete functions, reliable operation, and convenient and flexible use. It is equipped with our company's PT100 series high-temperature melt pressure sensor or PT200 series normal temperature pressure sensor as high-precision pressure measurement and control, and can be widely used in pressure display and automation control occasions in industries such as hydraulic, petroleum, plastic, rubber, printing and dyeing, textile, etc. It can also be matched with resistance strain type pressure sensors from other manufacturers; It can set upper and lower limit alarms, with LED alarm indication and relay contact output to control external actuators; Equipped with high-precision voltage output module, current output module, relay output control module, and communication module for users to choose from; This machine adopts a user-friendly operation method, which is easy to learn and operate.
