with 4 to 20 mA Transmitter
Item Number: 129-517, Rev. BA Page 1 of 2
Product Description
The transmitter-equipped Immersion Temperature
Sensor provides a 4 to 20 mA input to a controller. It
threads into a coupling on a piping system. The
sensor assembly includes an immersion well,
100 ohm platinum RTD sensing element, and a
transmitter located in the LB wiring housing.
See Figure 1.

 Power screwdriver with 1/4-inch hex extension or
medium flat-blade screwdriver
 1-1/4 inch open end wrench or equivalent
adjustable wrench
 Medium crescent wrench
 Pipe sealant
 Wire stripper
Expected Installation Time
3 hours
Prerequisites
 The appropriate field wiring within the maximum
wiring run length for the individual field panel or
equipment controller must be in place.
NOTE: All wiring must comply with National
Electric Code (NEC) and local
regulations.
 A 1/2-inch NPT mounting coupling must be
installed in the piping system at the sensor
location. Figures 2 and 3 show two types of
installation: pipe surface and pipe joint.
 Be sure you have the correct temperature range
sensor for the point location.
Instructions
NOTE: It is not recommended or necessary to
separate the well and the wiring housing to
install the sensor assembly. The LB wiring
housing should only be removed to replace a
damaged or defective sensing element.
1. Clean any dust away from the coupling for the
well.
2. Apply pipe sealant to the threads of the well and
insert the entire sensor assembly into the
coupling.
