The new range of GLD Small series gas sensors has been designed for:
- comply with EN 378 and F-GAS standards,
- avoid downtime or significant economic damage due to poor conservation food,
- contribute to the reduction of greenhouse gas emissions,
- provide for continuous monitoring of the environment where the refrigeration units are located,
- ensure the safety of people who are in the proximity of the unit.
The range of GLD small sensors allows connection to BOSS series supervision systems through a Modbus RTU RS-485 serial. When the leak is detected with settable thresholds, the sensor sends a digital or analog signal to the controller or supervisor connected to it.
The alarm can also be displayed locally with an acoustic and visual signal (optional accessory).
Features:
- available in compact version or with remote sensor,
- range -40/+50 C°,
- with optoisolated Modbus serial,
- pre-calibrated and quick-to-install spare sensors,
- “RILEVA TE” configuration APP,
- version with infrared sensor for CO2 – R744,
- version with electrochemical sensor for ammonia,
- version with semiconductor sensor for refrigerated gases, but managed with only 3 codes (each model can be configured via APP for gas groups as indicated below).

Rileva TE
It is possible to interface the gas detectors with a smartphone and the RILEVA TE APP. With the app you configure the sensor and its calibration, you can also check the operating status of the GLD mini, the current gas concentration and any alarm status.
