On- Line Ar Gas Detector
On- Line Ar gas detector product descrtption:
Online type epoxy ethane gas detector, On- Line Ar gas concentration and gas for use in a
variety of environments in real-time and accurate leak detection, imported electrochemical sensor and
microcontroller technology. Fast response speed, high accuracy, stability and repeatability. The
explosion-proof connection mode is suitable for all kinds of dangerous places, and is compatible with
various control alarm PLC, DCS, and other control system, can realize the scene alarm and alarm in
advance, 4-20mA/RS4 standard signal output, relay switch output display; perfect the technical
index and gas concentration value; at the same time has a strong variety of circuit protection function,
effectively prevent various man-made factors, lead to uncontrollable factors damage the instrument.
On- Line Ar gas detector product characteristics:? Imported electrochemical sensor has good anti-interference performance, long service life of 3
years;
? Using advanced microprocessor technology, fast response speed, high accuracy, good stability
and repeatability;
? This site has the detection function of acousto-optic alarm, gas concentration exceed the standard
immediate alarm is a security risk field;
? This scene with backlight large screen LCD display, display gas concentration / type / unit /
working condition etc.;
? Independent air chamber, sensor replacement is convenient, without replacing the field calibration,
automatic identification of the key parameters of the sensor;
? the full range of digital temperature automatic tracking compensation, to ensure the accuracyof;
