Oven Air Feed Control Using Digital Differential Pressure Switch / Transmitter

This Product is Available in Ex-version for Hazardous zone 2, zone 22, ATEX certified.

DE46 is a multi-function diff. pressure switch with an optional transmitter signal
output. It is suitable for accurate measurement of low pressure/ negative gauge
pressure or differential pressure of air and gases.
