616W series differential pressure
transmitter
product manual:
NEMA 4X protection with 0.25% accuracy, ranging from 0-1 inch water column to 0-100 psid
The 616W series differential pressure
transmitter can measure positive pressure, negative pressure and differential pressure with an accuracy of 0.25%. It uses a polycarbonate housing and NEMA 4X (IP66) protection for monitoring air or other compatible gases with an output of 4-20mA.
