Greystone Energy Systems LP-S Installation Instructions

in personal injury. Use electrostatic discharge precautions during installation and do not exceed the
device ratings.

MOUNTING

The transducer mounts on a vertical surface using the two integrated mounting holes. Ensure there is
enough space around the unit to connect the pressure tubing without kinking and to make the electrical
connections, avoid locations with severe vibrations or excessive moisture. Drill a hole in the duct and
insert so the probe point is facing into the air flow. The enclosure has a standard opening for a 1/2"
conduit and may be installed with either conduit and a conduit coupler or a cable gland type fitting. See
Figure 1.
The two mounting holes will facilitate a #10 size screw (not supplied). See Figure 1.
The enclosure has a hinged cover with a latch. Open the
cover by pulling slightly on the latch on the right side of
the enclosure and at the same time pulling on the cover, as
illustrated in Figure 2.
A 1/2" NPT threaded connection hole is provided on the
bottom side of the enclosure. Screw the EMT connector
or cable gland connector in until tight. See Figure 3. It is
recommended that weatherproof conduit or cable gland
fittings be used. The F style enclosure includes 1/2" NPT to M16
thread adapter and cable gland fitting. See Figure 3.
Two security screws are provided which can be installed to
help secure the cover once settings and wiring connections are
complete. See Figure 4.

Duct Low Pressure Transducer

INTRODUCTION

The Low Pressure Transducer can be used to measure positive,
negative or differential pressure in the ranges of 1"wc to 20"wc.
The highly accurate piezoresistive sensor is ideal for monitoring
pressure of non-corrosive, non-ionic working fluids such as clean
dry air or other inert gases. It features field selectable pressure
ranges and output signal types for the most flexible application.
Typical HVAC applications include monitoring of filter differential
pressure or clean room pressure. The output signal is factory
calibrated and temperature compensated for highest startup
accuracy and trouble-free operation.

BEFORE INSTALLATION

Read these installation instructions carefully before
commissioning the Pressure Transducer. Failure to follow these
instructions may result in product damage. Do not use in an
explosive or hazardous environment, with combustible or
flammable gases, as safety or emergency stop devices or in
any other application where failure of the product could result
