High Accuracy Gage
Pressure Transmitter
HAGP Series – Installation Instructions
INTRODUCTION
The high accuracy gage pressure transmitter is designed with a single remote
sensor that enables it to accept high pressure in several ranges up to 500
PSI, 30 Bar or 3000 kPa. All models can handle overload pressure 2X the
maximum full scale range and burst pressure is 5X the maximum full scale
range.
Features include field selectable pressure ranges and output signal types,
output reversal and slow-damping for the most flexible applications. The
pressure transmitter is fully factory calibrated and temperature compensated
for the highest start-up accuracy.
WARNING : Ensure that the maximum port pressure does not exceed the
highest pressure range of the device. For example, the maximum port pressure
on a 102 model is 100 PSI. Exceeding this may give erroneous readings or
damage the sensor. See Figure 12 for ratings.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the
transmitter. 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 a safety or emergency stop device or in any other
application where failure of the product could result in personal injury. Take
electrostatic discharge precautions during installation and do not exceed the
device ratings.
MOUNTING
The transmitter mounts on a vertical surface using the two integrated mounting
holes. The remote sensor cable connection should be located on the bottom of
the enclosure. The two mounting holes will facilitate a #10 size screw (not
supplied). See Figure 1. Ensure there is enough space around the unit to make
the electrical connections and that it is within an acceptable distance for
the length of remote sensor cable. Avoid locations with severe vibrations or
excessive moisture. The enclosure has a standard opening for a conduit
connector or cable gland type fitting.
The enclosure has a hinged cover with a latch. Open the cover by pulling
slightly on the latch on the bottom 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 left side of the
enclosure. See Figure 3. Screw the EMT connector or cable gland connector in
until tight. It is recommended thatweatherproof conduit or cable gland
fittings be used. The F styleenclosure includes 1/2″ NPT to M16 thread adapter
and cable gland fitting. See Figure 4.

Two security screws are provided which can be installed to help secure the
cover once settings and wiring connections are complete. See Figure 5.
PLUMBING
The stainless steel pressure sensor incorporates 1/4” NPT male threads for
connection to the pipe being monitored. See Figure 6. Do not allow material to
fall into the pressure ports as contamination could damage the sensors. It is
recommended to use Teflon tape to prevent leaks.
Remove the pressure sensor from the remote cable by unscrewing and pulling
apart from the remote cable boot as shown in Figure 7. Wrap 1/4” NPT male
sensor threads with Teflon tape. Screw into the sensor port on the pipe being
monitored until finger tight. Using an appropriate size wrench, tighten the
fitting until snug as shown in Figure 8. Reconnect the remote sensor cable by
aligning the remote sensor cable boot and screwing onto the sensor. See Figure
9.
CONFIGURATION
Most configuration is done using User Menu setting with LCD and push buttons
on the PCB. See User Menu section for details.
Warning: The transmitter must not have power applied during set up or
when making changes to the output signal.
OUTPUT SELECTION: The transmitter features user-selectable output signals of
4-20 mA, 0-5 Vdc and 0-10 Vdc. It is factory configured to operate in the
Current (4-20 mA output) mode, but can be changed to Voltage mode by moving
the output selection jumper from the position marked mA to the position marked
VOLT as shown in Figure 10.
In Voltage mode the output scale may be changed to either 0-5 or 0-10 Vdc by
accessing under User Menu.
WIRING
- Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage.
- Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors. Make all connections in accordance with national and local codes.
- Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wiring diagram for the applicable power supply and output signal type.
- Connect the plus DC or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply Common is connected to the COM terminal. DO NOT connect power to the OUT terminal as the device will be damaged. It has half-wave power supply so the supply Common is the same as the signal Common. See Figure 11.
- The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper connection before applying power.
- If using the Zero function, connect the Remote Zero Switch between the ZERO and COM terminals.
