E2618-CH4 Methane transmitter

Features

• Stable long-life metal-oxide / pellistor sensor
• Range 0...100% LEL CH4
• Resolution 0,1 / 1 % LEL CH4
• 2 × 4-20 mA or 0-10 V, RS485

Description

Methane transmitter E2618-CH4 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include underground parkings, boiler houses, kitchens, and other confined spaces, where potentially explosive concentration of methane can accumulate.

The instrument utilises fully calibrated metal-oxide semiconductor or pellistor gas sensors with excellent repeatability, stability and long lifetime.

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