The main goal of the company is to live a satisfactory memory to all the customers, and establish a long term win-win business relationship. For more information, be sure to contact us. And It is our great pleasure if you like to have a personally meeting in our office.
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.
