Gas Detector Real-Time Concentration & Temp Readout RS485 4-20mA

Industrial Ex Gas Detector with Multi-Function: IP66, Sound-Light Alarm, Real-Time Concentration & Temp Readout | Dual Output Options

RS485 Combustible Gas Detector 4-20mA with Real Time Concentration / Temp Readout

1.Product Overview

The GTYQ-JSY-201/A industrial-grade point gas detector is an explosion-proof device integrating real-time concentration display, audible/visual alarms, and ambient temperature monitoring.

Operating on natural diffusion principle with catalytic combustion sensing technology, it delivers superior sensitivity and measurement consistency. The industrial-grade segment LCD simultaneously displays gas concentration and ambient temperature. Upon reaching preset thresholds, the unit triggers strobe/horn alarms and can activate ventilation systems. Featuring 4-20mA output for direct DCS integration or RS485 connectivity with our M201 control panel for centralized monitoring. The PowerBus 2-wire option simplifies installation. Built with embedded microcontroller architecture for reliable operation with intuitive functionality.
