815DT Smart Differential Pressure Transmitter

Brand: SOR Inc

The 815DT smart differential pressure transmitter is a rugged, compact, lightweight, loop-powered instrument that is ideally suited for hazardous locations and hostile environments where space is limited.

The 815DT offers many industry standard outputs to meet applications where low-cost, discrete, and continuous monitoring is required or preferred.

This versatile instrument may be used to reliably measure differential pressure, level, or flow.

A software CD is included in the kit and the software (Version 4.0.0.0). 

The 815DT is easily configured using HART®7 Communication Protocol and Modbus RTU Serial Communications and the zero and span set points can be easily set with a magnet.
