Features

• Stable long-life metal-oxide sensor
• Range 0...100% LEL or 0...1000 ppm
• Resolution 0,1% LEL or 1 ppm
• Two SPST relays
• 2 × 4-20 mA or 0-10 V, RS485

Description

Solvent vapor detector E2611-VOC is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include storages, painting chambers and other confined spaces, where toxic or potentially explosive concentration of volatile organic compounds can accumulate.

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

According to user's preferences the detector can be ordered for either fire prevention, (range 0...100% LEL) or for toxicity prevention (range from 0...1000 ppm).

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.
