PESO & ATEX Certified Wall Mounted Digital Online Gas Detector by Websoft Solution

Digital Gas Transmitter is a field mounted gas detector for the continuous monitoring of hazardous gases. It provides an industry standard 4-20 mA output signals that can be connected to any control system (DCS, PLC, etc.). It also provides RS-485 MODBUS-RTU digital output signal. It is available for a large variety of toxic and flammable gases such as Combustibles (%LEL), Oxygen, Ozone, Carbon Monoxide, CO2, Carbon Disulfide, Vinyl Chloro Monomer, Styrene, Acrylonitrile, Hydrogen Sulfide, Mercaptan, Phosphine, Phosgene, Bromine, PCl3, Hydrogen Fluoride, POCl3, Ammonia, Chlorine, Hydrogen, Formaldehyde, Methane, LPG, Acetylene, Butanol, Hydro Carbon, VOC (Isobutylene), SO2, NH3, HCN, HCL, NO2 etc.

It consists of two parts, Digital Transmitter & Smart Gas Sensor Module. The smart gas sensor module contains a gas sensor and necessary electronics to store the calibration data in its memory. This makes it independent of transmitter module & can work on any digital transmitter. The transmitter recognizes the smart sensor & all the data stored in it & functions accordingly for the programmed gas.

The digital transmitter is housed in an explosion proof (“exd” certified) wall mountable enclosure and is virtually maintenance free. Its revolutionary design utilizes advanced micro controller & non volatile memory devices that allow for enhanced diagnostics & fault analysis. Advanced design features make installation & operation simpler & user friendly.

Normally only a periodic calibration & bump check is needed to assure dependable performance. Field interchangeable plug in sensor module enables users to replace the calibrated gas sensor module at ease & as per their requirements on the site. Sensor module from the transmitter requiring calibration can be sent to the laboratory for calibration.

Gas sensor modules are available for many gases of interest. These modules include one of the following sensors viz Electro-Chemical detector, Non dispersive infrared detector, Catalytic bead detector, Photo-Ionization detector, Semiconductor thin film detector etc.
