Spark Protection for

Remote Sensing Elements

Spark protection is a standard feature of the sensing element

circuit.

If additional spark protection is supplied for a remote sensing

element, use the installation instructions provided with the

spark protection. Below are instructions for our most common

spark protector, Part # 377-0001-019.

A. Attach the mounting link on the spark protector to the

sensing element center connection screw.

B. Connect the green wire from the spark protector to the

ground screw.

C. Feed the coax cable into the condulet.
D. Connect the coax cable center wire (cw) to the spark

protector and the ground wire (gnd) to the ground screw

as shown in

Figure 2-9

E. Connect the shield wire to the Cote-Shield terminal

(sh).*

* For sensing elements that do not have shield connections,

clip the shield wire as shown in

Figure 2-8
