Overview

The DLP Series is based on a piezoresistive, silicon sensing element which senses Differential

Pressure and provides an analog output. The hinged cover on the DLP can be easily opened using

the integrated locking tab on the side of the enclosure. This allows for easy access to the zero

function and field selectable ranges and outputs. The DLP Series also includes an optional, five digit

LCD for installation and monitoring support. Field selectable analog outputs include 0-5 and 0-10

VDC, or 4-20 mA which correlate to a uni or bi-directional pressure range from 0-0.1” up to 0-40” of

water column, depending on your model selection. Each unit has up to 8 field selectable, uni or bi-

directional ranges. Options include a Pitot Tube or Din Rail Clip.

Applications: Building and Duct Static Pressure, Filter Monitoring, Air Flow Measurement, and

Process Control
