INTRODUCTION
General Description
The Temperature Sensor for Pipes (TSP) is a temperature sensor
based on a Resistive Temperature Detector (RTD) coupled to an
electronic circuit with an on board microprocessor. It gives a linear current
output (4 to 20 mA) proportional to the temperature detected by the
sensing element. The RTD element and the electronics are all integrated
in the same mechanical assembly in order to reduce wiring and installation
cost.
These features make the TSP very versatile, easy to use and able to
fullfill your application requirements.
Models Available
The TSP is available in NPT pipe thread configurations and several
standard temperature ranges as well as factory set custom ranges.

INSTALLATION
Unpacking
The TSP comes completly assembled and ready to install.
Please verify that no parts are missing and do a visual inspection of the
TSP to ensure that none of the components have been damaged during
shipment. If you notice any damage, please contact the shipping agent
immediately, as they are responsible any damage while in transit.
Mechanical Installation
Use a suitable thread sealant on all pipe threads. The same standard
installation practices should be observed as with a standard RTD
assembly. Care should be taken so the transition, housing the electronics,
is maintained within the specified temperature limits.
Electrical Wiring
The TST is a loop powered device that comes with two wires.
Red (+V) and White (-V) are for the 4-20 mA current loop power and signal.

Connect the TSP wiring as shown in Figure # 1
Wiring Connections:
• Connect the Red wire from the TSP to the positive side of the power supply.
• Connect the White wire from the TSP to the positive side of the current indicator
or measurement device.
• Connect the negative side of the current indicator or measurement
device to the negative side of the Power Supply in order to close the
series current loop.
