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 selectable voltage output version.
BENEFITS/FEATURES
• Supports critical applications due to 0.25% accuracy on most ranges
• Maintains process quality with a stable accuracy
• Allows for use in critical processes with pressure ranges as low as 0.25 in w.c.
• Ensures a long service life in heavy industrial processes with the robust stainless
steel housing
