Combustible gases transmitter E2615-LEL is a new low cost device intended to use in HVAC applications.
The device operates in the range of 0-100 % LEL.
The transmitter is based on a miniature pellistor sensor with long lifetime (> 3 years). The sensor requires no field recalibration during the whole lifespan.
The analog output of the device is user settable to 4-20 mA or 0-10 V.
The device is available either in a slotted IP20 enclosure or in a IP65 enclosure.
