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

Installation
Precautions
Do not switch pressure range and output mode when power is on. Make sure to power off the unit first, then set the DIP
Switches to the correct positions and then power on the transmitter.
Mounting
Find a suitable location for the enclosure. The DLP has 2 two mounting holes located on the top and bottom flanges. Drill
pilot holes for the (2) #8 x 3/4” self-drilling screws (supplied). Use the enclosure flange as a guide, or use the dimensions
listed in Figure 1. Mount the unit vertically with the brass fittings pointing towards the ground. This ensures that any
condensation that may form in the tubing does not have an effect on the pressure sensor. If mounting the unit horizontally,
a slight zero shift may occur and care must be taken to prevent moisture from building up in the sensor.

Din Rail Mounting (Optional)
Attach the DIN Rail Mounting accessory to the back of the enclosure using the two screws provided. To mount the sensor
on the DIN Rail, place the bottom of the DIN Rail Clip into the 35mm DIN Rail and push the unit upward to engage the
spring clip. Now press the top of the unit back until it locks into place – see Figure 2.
Figure 2
Pitot Tube Installation (Optional)
Slip the rubber washer over the threaded end of the pitot tube, keeping the washer as close to the threaded end as
possible. Fasten the pitot into the threaded insert on the back of the enclosure. Press the rubber washer against the
enclosure - see Figure 3.
Figure 3
Tubing Setup When Pitot Tube is Installed
Units will be shipped with silicone tubing attached to the high and low pressure barb fittings. The silicone tubing will need
to be removed from the High Pressure (H) barb fitting and secured onto the pitot tube barb fitting. This will leave the high
pressure barb fitting open to atmosphere, and the Low pressure barb fitting remaining at default setup.
Pressure Connections
The recommended connection tubing is ¼” O.D push-on tubing (1/8” to 3/16” I.D.). For best results, all tubing lengths
should be limited to a maximum length of 75 feet (23 meters). Longer runs will affect the response time.
