In both new and retrot applications, the WORM®
Flexible Sensors for Thermowell Temperature
Assemblies replace restrictive straight sensor probes
with a universal sensor strategy that will save you
time and money.
Unique Flexible Design Installs in Minutes
With straight sensors, you have to remove the
connection head, and sometimes thermowell
assembly components, to get the sensor into the
thermowell. The WORM bends right through the
top or face of the enclosure. It slides through the
enclosure’s conduit port, and into (or out of) the
thermowell without having to remove the enclosure
or any assembly components (Figure 1).
Figure 1. The WORM lets you replace a sensor without removing
the enclosure or disassembling the thermowell.
Features
• Universal, trims to
thermowell length.
There’s no need to stock an
expensive array of different
sensor lengths. With a
quick measurement and a
simple trim-to-length, the
WORM handles nearly
every thermowell assembly.
• Ideal for hockey-puck, connection head and
dual-sided enclosures. The innovative WORM
provides cost and time advantages for all types of
temperature transmitter enclosures.
• Popular RTD and thermocouples. Standard
sensor types include 100 and 1000 ohm platinum,
nickel and copper RTDs; plus J-, K-, T-, E- type
thermocouples.
• Faster response time. The WORM delivers step
response times 13% faster than standard sensors.

Each of the three installation options uses different
parts from the installation kit; expect to have parts left
over after installation. Read through all steps for the
enclosure type prior to beginning installation.

Field Enclosure Installation
(Including Moore Industries’ DH & BH enclosures)
Installation Components Required: Sensor Probe,
Spring, Cap, Clip, 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. Snap the Clip onto the Cap. Then slide the Cap/Clip
combination over the sensor wires onto the top of the
Spring.
4. 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).
5. Using pliers, grasp the Cap/Clip combination by the
niche at the top of the Cap, and insert it into the
enclosure’s sensor entry port to compress the WORM
Spring into the thermowell. Reinstall the instrument into
the enclosure. Connect the sensor wires.

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

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.
