You're currently on:
Universal gas detector with 1-W and RS 485 communication which is produced by Polimex Holding's specialized team. It gives the ability to register gas saturation of carbon monoxide, methane gas and LPG. Gas Detector 3GD1-W Relay uses 3 single elements for measuring different gases correctly. It has to be powered with 12 volts DC and has 1-W/RS485 communication interfaces for connection with iCON1XX controllers. Also one built in relay output can activate other systems directly which means that once if the detector is set it can work stand lone. Settings and visualization can be done via Andromeda Pro software. There you can set normal functioning parameters and limits. Also you can visualize data in real time, store event data and set controllers output which can activate an alarm, ventilation or other. Ability to connect up to 128 detectors on one line RS485.
Short sensor description
Sensor for CO
A semiconductor gas sensor, taking into account the presence of carbon monoxide (CO) at a concentration of 10 to 1000 ppm (parts per million). The sensor generates an analog signal on the basis of reading gas concentration. Output needs to add a resistor - RL, whose value can be calculated (approximate value at 5V - 20k). Operate from -10 ° C to 50 ° C and consume up to 150mA when powered with 5V.
Sensor for methane gas
Semiconductor gas sensor, considering the presence of methane gas in concentrations of 300 to 10000ppm (parts per million). The sensor works with a simple interface and a signal based on the concentration of the gas using one of the analog inputs on your microcontroller. Operate from -10 ° C to 50 ° C and consume up to 150mA at 5V.
Sensor for LPG
Semiconductor gas sensor, considering the presence of propane-butane, isobutane at concentrations of 300 to 10000ppm (parts per million). The sensor works with a simple interface and a signal based on the concentration of the gas using one of the analog inputs on your microcontroller. Operate from -10 ° C to 50 ° C and consume up to 150mA at 5V.
