Flexible Sensors for Thermowell 

Temperature Assemblies

Head-Mount Enclosure Installation 

 

(Including Moore Industries’ LH enclosure)

 

Installation Components Required: Sensor Probe, Spring, 

Cap and Spacer(s).

 

1.  

Determine the length of the thermowell assembly (see 

the illustration to the left).  Cut the WORM Spring to be 

between 1 and 1½ 
inches  

longer 

than the 

length of the 

assembly (this is 

necessary so that the 

Spring’s compression 

securely holds the 
Sensor Probe to 
the bottom of the 

thermowell).  

2.  

Ensuring that 

the uncut portion 

of the Spring faces 

down towards the 
Sensor Probe, slide 

the Spring over the 

sensor wires and 
onto the end of the 
Sensor Probe.

3.  

Slide the Cap over 

the sensor wires onto 

the top of the Spring. 

 

 

4.  Remove the 

instrument from the 
enclosure.  Insert 

the WORM sensor 

into the thermowell.  

Slide the appropriate 

length(s) and number 

of Spacers to keep 

the WORM Spring 

straight inside the 
thermowell assembly 

lag (Spacers may not 

be required).

 

5.  

Reinstall the 

instrument into the enclosure, compressing the WORM 

Spring into the thermowell with the bottom of the 

instrument.  Connect the sensor wires.

 

Generic Enclosure Installation

 

Installation Components Required:  

Sensor Probe, 

Spring, Stopper and Spacer(s).

 

1.  

Determine the length of 

the thermowell assembly 

(see the illustration to the 

right).  Cut the WORM 

Spring to be between 1 

and 1½ inches 

longer

 

than the length of the 

assembly (this is 

necessary so that the 

Spring’s compression 

securely holds the 
Sensor Probe to 
the bottom of the 

thermowell).  

2.

  Ensuring that 

the uncut portion 

of the Spring faces 

down towards the 
Sensor Probe, slide 

the Spring over the 

sensor wires and 
onto the end of the 
Sensor Probe.

3. 

 Remove the 

instrument from 

the enclosure (if 

necessary).  Insert 

the WORM sensor 

into the thermowell.  

Slide the appropriate 

length(s) and number 

of Spacers to keep 

the WORM Spring 

straight inside the 
thermowell assembly 

lag (Spacers may not 

be required).

4.

  Slide the Stopper 

over the sensor wires 

onto the top of the 

Spring.  Push the 

Stopper firmly into the thermowell entry port to compress 

the WORM Spring into the thermowell. 

 

5. 

 Reinstall the instrument into the enclosure.  Connect the 

sensor wires.
