Positive, negative and differential pressures can be measured within a full span accuracy of ±0.25. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases then sending a standard 4-20 mA output signal. Design enables operation in 2-wire current loops

Senses very low pressures of air and non-combustible, compatible gases and sends a standard 4-20 mA output signal. Positive, negative and differential pressures can be measured within a full span accuracy of ±0.50%. This weatherproof unit is enclosed in a polycarbonate case, designed to meet (IP66/NEMA 4X).
