Strap-On Mounting (C7021K, C7023K,
C7041K)
Strap-on mounting is well-suited for retrofit applications where
installation costs can be reduced by not draining the system.
The C7021K, C7023K, C7041K Sensor mounts on metal pipes
from 1-5/8 inch to five inches in diameter using the straps
supplied. Clean the surface of the pipe where the sensor
makes contact before mounting (remove insulation from the
pipe at the point of installation if necessary). Thermal
compound is recommended with the strap-on C7021K,
C7023K, C7041K Sensor. Locate the sensor on the discharge
pipe within 3 feet (0.9m) of the boiler. See Fig. 16.

NOTE: Insulation around the contact area increases
sensor accuracy.
Button Probe Mounting
The C7021P, C7023P, C7041P Button Probe Sensor design
simplifies mounting into a variety of standard structural
materials.
The locking nut can be used to secure the probe. See Fig. 18.
The plastic spacer helps insulate the probe from drywall, wood,
or other material in which the probe is mounted. The spacer is
sized to fit snugly into 1/2 in. metal conduit. See Fig. 17.
NOTES:
— The plastic spacer is threaded for easy installation.
— Use of both the locking nut and spacer requires
cutting spacer to shorter length.
C7041P MOUNTING RECOMMENDATIONS
Determine the proper location based upon the following:
— Mount the probe to an inside wall approximately 54 in.
(1372 mm) from the floor (or in the specified location) to
allow exposure to the average zone temperature.
— Do not mount the probe to an outside wall, a wall containing
waterpipes, or near air ducts.
— Avoid locations exposed to register discharge air, or
radiation from lights, appliances, or the sun.

Bullet Probe Sensor Mounting (C7021N,
C7023N, C7041N)
The bullet probe sensor is a water-resistant sensor that
provides a cost-effective solution for surface contact
temperature measurement of conditioned water pipes, low
pressure steam or refrigerant lines. These sensors are ideal for
applications where immersion wells are not practical to install.
These sensors can also be use to sense air temperature.
