Gas Sensors

Evotrox gas sensors protect people and equipment in cold storage, chemical, pharmaceutical and oil and gas plants. They fall into two groups: gas transmitters and gas leak detectors.

• SENSE-GT100 is a weatherproof transmitter for one target gas, with a 2.4-inch display, a 4–20 mA output, a relay, RS485 Modbus RTU and Ethernet.
• SENSE-GT101 is a flameproof IP65 transmitter for hazardous areas that can carry up to three gas sensors in one unit.
• SENSE-LD100 and SENSE-LD101 are leak detectors with 4–20 mA, RS485 and relay outputs and alarm indication. The LD101 has a flameproof enclosure.

The sensor technology depends on the gas: electrochemical, catalytic, pellistor or NDIR. The configured example is ammonia (NH₃) from 0 to 1000 PPM, widely used in cold storage and refrigeration. Tell us your gas and area, and we will recommend the right model and calibration.
