Line Sensing
The line sensing control systems activate the heating cable when the pipe temperature drops below the desired setpoint. The
sensor must be secured to the pipe with aluminum tape and the insulation must be sealed where the capillary comes through.
The device should be mounted above ground in an area without heavy pedestrian or equipment traffic. To avoid thermal in-
terference with the sensor, it is important that the sensor is installed at 90 degrees from the nearest heating cable or centered
equally between cables if more than one heating cable is used. The sensor should ideally be installed at the end of the circuit
but can be installed at any location that is at least 3 feet away from any heat sinks. See installation detail AD19.

RBF
Heat Trace or Pipe
Sensor
The RBF sensor measures the surface tempera-
ture of process piping that is carrying products
whose temperatures must be controlled to pre-
vent freeze-up, or to maintain a viscosity level so
that the inner medium will flow. The Thermocouple
or RTD Sensor Element is made up with a 316SS
sheath and has a stainless-steel mounting pad.

RBF-HT
RTD Heat
Trace Sensor
The RBF-HT sensor measures the surface tempera-
ture of process piping that is carrying products
whose temperature must be controlled. The RTD
sensor element is made up with a 316 SS sheath
and can be installed directly to a controller or junc-
tion box using the 1/2” conduit fitting.

E-100
Line Sensing
Thermostat
The E100 remote mount thermostats utilize a stain-
less-steel bulb and capillary design to accurately
sense temperature at key points along a pipe. The
thermostats are epoxy coated to seal from moisture
and contaminants in compliance with NEMA 4X
requirements.
