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.
