INTRODUCTION

The differential pressure transmitter is designed with dual remote 

sensors that enable it to accept high pressure in ranges up to 5 

PSI to 500 PSI. All models can handle overload pressure 2X the 

maximum fully 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, port swapping and 

bidirectional measurements for the most flexible applications. The 

output signal is factory calibrated and temperature compensated 

for the highest start-up accuracy.

WARNING :  Ensure that the maximum individual port pressure 

does not exceed the highest pressure range of the unit. For 

example, the highest individual port pressure on a 102 Range 

Code is 100 PSI. Exceeding this may damage the sensors and 

give erroneous readings.  See Figure 12 for ratings.

BEFORE INSTALLATION

Read these instructions carefully before installing and 

commissioning the dewpoint 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 cables. Avoid locations with 

severe vibrations or excessive moisture.  The enclosure has a 

standard opening for a conduit connector or cable gland type 

fitting. In this position the High port is on the left and the Low 

port is on the right as shown on the PCB.

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 in the left 

side of the enclosure as shown in Figure 3. Screw the EMT 

connector or cable gland connector in until tight. See Figure 4. 

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.

Two security screws are provided which can be installed to 

help secure the cover once settings and wiring connections 

are complete. See Figure 4.
