Description

Combustible gases detector-transmitter E2611-LEL is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include underground parkings, boiler houses, battery charging rooms, kitchens, and other confined spaces, where potentially explosive concentration of combustible gases can accumulate.

The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime.

Two relays with closing contact may be used for remote signalling or ventilation control. Two alarm set-points are user settable. Internal buzzer gives sound alarms.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
