representative for assistance. Type 089 includes:
•  One pressure sensor bulb
•  One 10 foot electrical cable with connector

•  One Installation and Operation Manual IOM-T-089

Preparation

Tools Required

•  22 mm or Crescent wrench

•  Flathead screwdriver

Materials Required

•  Pipe joint compound or PTFE tape
•  1/4" steam gauge siphon (pigtail) 

•  1/4" to 

1

8

" FIPS reducing coupler

Installation Location

•  The Pressure Sensor 089 must be installed downsteam 

of a 1/4" steam gauge siphon (pigtail) to prevent premature 

failure.

•  Keep dry. Avoid potential leakage onto the sensor.

Step 1 – Rough In Wiring

•  The sensor cable is 10 feet (3 m) in length. This can 

be extended up to 100 feet (30 m) using 3-conductor 

18 AWG solid or stranded cable. The cable is color 

coded with black, red and green wire jackets.

•  Strip wire to 

3

8

" (10 mm) for all terminal connections.

As with any electrical product, care should be taken to 

guard against the potential risk of fire, electric shock, 

and injury to persons.

Step 2 – Mounting

•  Apply pipe joint compound or PTFE tape to the  

sensor threads.

•  Thread sensor into the tee. Tighten with wrench.
•  Connect the cable to the sensor using the Metri-Pack 

electrical connector.

•  Should the cable need to be disconnected from the 

sensor bulb, use a flathead screwdriver to release the 

electrical connector spring-loaded clip.

Step 3 – Wiring

Conduit Connector

•  Pull wires through a conduit as required by electrical 

codes.

Terminating

•  Terminate the black conductor to the control’s  

power common.

•  Terminate the red conductor to the control’s 5 V(dc) 

reference voltage.

•  Terminate the green conductor to the control’s ratiometric 

signal input.
