产品介绍
Product Name: fixed type combustible gas detection alarm
Product model: ES10B11-EX
Product description:
ES10B fixed gas detection instrument is no vision technology based on ES10A to create one of the new gas detector, using imported sensor and a new 32 bit low-power processor; the dashboard display interface, and the numerical progress bar shows at the same time, beautiful appearance; circuit adopts 4 layer wiring, the weak signal and stronger anti-interference high precision; independent import 16 bit AD chip and signal processing algorithm, the measurement data accuracy is higher and more stable; 4~20mA, RS485, 200~1000HZ multiple output signal can be selected, convenient access, PLC, alarm controller DCS control system; explosion-proof structure design can be applied to various industrial dangerous places; products are widely used in metallurgy petroleum, petrochemical, municipal, chemical and other industries.
Product features:
The imported high performance sensor, long service life;
The independent 16 bit AD chip, 4 layer circuit board design, the stronger the weak signal and anti-jamming ability;
The dashboard display interface design, beautiful reading, humanized design details;
The white, orange, red tricolor backlight design, normal alarm, status indication, stick out a mile;
The mg/m3, ppm, VOL, LEL various units can choose;
- equipped with embedded 32 bit ultra low power processor, with a unique signal processing algorithm, fast response speed, high measuring precision, stability and repeatability.
The anti automatic protection function of impact of high concentration of gas, can restore the factory settings, to prevent misoperation;
The instrument configuration of infrared remote control, the remote control operation, without opening the cover, simple and convenient;
The third line of 4 ~ 20mA, RS485, 200~1000HZ signal output optional, relay output, data recovery, data storage and other functions.
The two cable inlet, convenient installation;
The independent air chamber structure, sensor replacement is convenient, without calibration;
] first-class mechanical design, the air chamber by military quality of high strength aluminum, resistant to wear and rot turbidity, suitable for harsh industrial environment, scientific and reasonable gas chamber is designed to ensure the accuracy of the sensor for real-time monitoring of;
Exd II CT6 - the level of explosion-proof, explosion-proof electrical national inspection center certification.
