G T- P PIPE TEMPERATURE SENSOR
Accessory for chilled beam control
PRODUCT DESCRIPTION
INTRODUCTION
GT-P is Lindinvent’s sensor unit for temperature measurement on a cooling beam pipe.
The GT-P pipe temperature sensor with its two interconnected modules. The pipe section is not included.
APPLICATIONS AND FEATURES
The GT-P, in combination with Lindinvent’s interface
LINDINSPECT, enables troubleshooting for:
- Non-functioning actuators
- Unvented pipelines
- Clogged valves
- Incorrect pipe connections
- Transmission losses in the piping system
- Condensation protection
The sensor unit consists of a sensor module and a module for signal conversion to AIN. The modules are interconnected via an insulated 2-conductor cable.
The sensor module is a small circuit board with a temperature sensor. The module is attached to the pipe using a mounting strap.
The signal conversion module is mounted directly onto the regulator’s AIN terminal.

GT-P in place. The sensor module is connected to the incoming cooling pipe.
The signal conversion module and the valve actuator are both connected directly to the chilled beam controller.
INSTALLATION AND CONNECTION
Note: The control unit must be powered off when connecting the GT-P!
For guidance on proper installation, see the instructions and illustrations in this product description.
- Attach the sensor module to the pipe using a mounting strap.
- Connect the signal conversion module to the controller’s AIN block terminal according to the external wiring diagram.
- Make an opening for the cable to the sensor module with pliers and cut along a selected marking for a thinner cable.
- The lid to the controller housing is used for fixing cables.
