Excellent quality China Universal Rtd/Tc/Mv High Stability Gas Detector with 4-20mA/Hart Protocol

Short Description:

This series of detectors adopts integrated functional module design, which is convenient for on-site hot swapping and replacement. It can be equipped with various types of sensors, such as catalytic sensor, semiconductor sensor, electrochemical sensor, infrared (IR) sensor, photoion (PID) sensor, etc. and can detect various toxic and combustible gas concentrations (ppm /% LEL /% VOL) on site. The detector has the characteristics of flexible combination, quick and easy replacement, stable performance, good consistency, high sensitivity, low power consumption, multiple outputs and optional detection methods. It is widely used in petroleum, chemical industry, pharmacy, steel, special industrial plants and other places with combustible or toxic and harmful gases.

ACTION gas detectors are OEM & ODM supported and true mature devices, long-tested in millions of projects domestic and overseas since 1998! Don't hesitant to leave your any inquiry here!

Product Selling Point

1) 4 ~ 20mA standard signal, supporting HART protocol

Lightweight design, three wire system (4 ~ 20) mA standard signal, using first-line brand imported sensor, supporting HART protocol

2) Highly-integrated functional module design

The sensor module integrates a sensor and a processing circuit, to complete all data operation and signal switching of the detector independently. Its unique heating function expands the detector’s low temperature service capability. The detector module is for power supply, communication and output functions;

3) Overlimit protection for high concentration

In case of overlimit of high concentration gas, the sensor module can cut off power supply automatically. Detection works every 30s until the concentration is normal and power supply is resumed. This function can prevent reduction of the sensor’s service life resulted from being submerged in high concentration gas;

4) Standardized digital interface

Standard digital interfaces are used between modules. Anti-misplug gold-plated pins are good for on-site hot plug replacement;

5) Flexible combination and multiple output modes

Multiple detector modules and multiple types of sensor modules can be combined flexibly to form detectors with special output functions and applicable to different targets to meet customers’ customized demands;

6) Replace a sensor as easy as replacing a bulb

Sensor modules for different gases and ranges can be replaced freely. No calibration is required after replacement. That is, the detector can read ex-factory calibrated data and work immediately. In this way, the product has a longer service life. Meanwhile, detection calibration can be done easily at different sites, avoiding complicated dismantling process and difficult on-site calibration and reducing later maintenance cost;

7) On-site LED concentration display, and diversified calibration modes

Highlight LED real-time concentration display, with farther and wider visual distance and angle, applicable to industrial environment requirements; the detector can be set/calibrated in different ways, such as by keys or by an IR remote controller or a magnetic bar, and it is easy to operate;

8) Explosion-proof design

Enclosure of this product is made of cast aluminum or stainless steel materials and its explosion proof grade reaches Exd II CT6 Gb.
