Description
Dwyer SERIES IDPT INDUSTRIAL DIFFERENTIAL PRESSURE TRANSMITTER
±0.25 or ±0.5% FS Accuracy, Ranges 0 to 10″ w.c.
The Series IDPT Industrial Differential Pressure Transmitter features a rugged, water resistant housing and highly stable accuracy for a long service life in most industrial applications. This pressure transmitter utilizes a capacitive pressure sensor on ranges 0 to 0.25 in w.c. to 0 to 1 in w.c. and a piezo sensor on ranges 0 to 2.5 in w.c. to 0 to 10 in w.c., both of which offer accuracy options of 0.25% or 0.5% full-scale. The cap cell allows the IDPT to maintain critical processes in industrial applications. The series offers a 4-20 mA 2-wire version for a loop powered current output as well as a 0-5 V/0-10 V
