• Resolution 1 ppm SF6
• Two SPST relays (option)
• 2 × 4-20 mA or 0-10 V, RS485

Description

Sulfur hexafluoride detector-transmitter E2638-SF6 is a member of PluraSens® family of multifunctional measurement instruments.

Applications include SF6 leakage control at power plants.

The instrument utilises a fully calibrated and temperature compensated optical NDIR gas sensor with excellent repeatability, stability and long lifetime.

Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.

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.
