AT-EG01 LPG Gas Detector is designed for fixed installation in areas where LPG leakage may occur. According to the product manual, the AT-EG01 gas detector can be equipped with a corresponding sensor module according to the target gas, and the target gas, detection range and alarm setpoints are specified on the product nameplate.
The detector provides real-time gas concentration display and current alarm status indication. It supports 4-20mA analog output, RS485 digital communication with Modbus RTU protocol and passive relay contact output for alarm or system linkage.
With die-cast aluminum housing, Ex d IIC T6 explosion-proof rating, IP66 ingress protection and DC24V industrial power supply, AT-EG01 LPG Gas Detector is suitable for LPG leakage monitoring in gas storage areas, LPG cylinder rooms, gas pipeline areas and other industrial gas safety applications.

4-20mA 3-wire connection: 24V+, 24V-, Signal
RS485 4-wire connection: 24V+, 24V-, A+, B-
Communication settings: 9600 / 4800 baud, 8 data bits, no parity, 1 stop bit, Modbus RTU protocol
Relay output: passive relay contact, max. 250VAC, 2A
Relay output mode can be set as standard mode or pulse mode.
Standard mode: relay closes upon alarm and remains closed.
Pulse mode: relay closes upon alarm and opens after 3 seconds.
The detector must be installed where gas leakage is likely to occur.
For gases denser than air, the detector should be installed near the potential leakage source at a height of 0.3 to 0.6 meters above the ground or floor level, with the sensor element facing downward.
General installation notes:
Choose a location free from impact, vibration and strong electromagnetic interference.
Ensure easy access for maintenance and calibration.
Keep a minimum 0.5 m clearance from surrounding pipes and equipment.
Route the cable through the cable gland.
A sealing operation with 2 cm of epoxy resin potting compound is required at the wiring port.
Do not open the cover when energized.
Use proper grounding through the internal and external grounding bolts.
