SC-T, Flying Lead Contact Temperature Sensor
Features
Thermistors and PT sensing elements to fit your system
Strap-On mounting for pipes or arched surfaces
Simple installation
Wide range of temperature probes
Including 2m (6.5ft) wire
Applications
Measure temperature for heating, ventilation and air conditioning
applications
For heating or cooling mode detection in 2-pipe systems
As frost protection sensor
Temperature sensor
The sensor measures the temperature by use of a glass packed thermistor
with a negative temperature coefficient (NTC), a platinum film (PT) or a nickel
thin layer (NI) based probe. Its resistance changes according to the
temperature. The change follows a specified curve. A summary of such curves
is printed on the back of this document. Contact our sales department for
curves or sensing elements not yet listed below.
Compensating conductor resistance
The length and type of conductors used to connect the sensor to the
measuring electronic influences the accuracy of the measurement. Especially
for elements with low resistance this has to be taken into account.
Compensation needs to be performed by the measurement electronics.

Installation
Mount the sensor on a supply or return pipe depending on application.
Make sure the maximum allowed temperature limit is not exceeded.
For better temperature transfer between sensor and medium use heat
conducting paste or heat conducting pads.
If possible place the sensor on the upper side of the pipe to prevent
permeation by condensate.
Bend the wings of the contact sensor to fit to the radius of the pipe.
Place the heat conducting pad or liquid between pipe and sensor and use the
tightening strap to fix the sensor to the pipe. Use moderate torque, do not
crush the sensor.
