Differential Pressure Sensor Air
Differential pressure transmitter with 8
selectable ranges and Modbus funtionality.
NEMA 4X / IP65 rated enclosure. For
monitoring over-, under or the differential
pressure of air and other non-flammable
and non-aggressive gases. Typical
application in HVAC systems for monitoring
air filters, fans V-belts or fire and smoke
control dampers. Options available with
LCD display and Auto-Zero function.
