Description
Introduction
Anyone selecting a component for temperature measurement wants to know in advance whether the version fits the existing control system and installation location. The Thermokon PR25 NTC1.8k surface Sensor is a passive cable probe from the PR25 product family for measuring temperature on a surface. The NTC1.8k Sensor element, the IP65 protection rating and the robust USE-S housing make this version relevant for HVAC installations where a clear and carefully selected measuring probe is required.
This version carries article number 616386 and is designated T100 L2000. This allows an engineer to compare the Sensor specifically with the requirements of an installation, an existing wiring diagram or a replacement request.
Key features
- Targeted surface measurement: designed as a cable probe and surface Sensor for temperature.
- Passive connection: equipped with an NTC1.8k Sensor element for use in suitable control systems.
- Protected version: protection rating IP65 for installations where suitable enclosure protection is desired.
- Practical mounting base: supplied with mounting base, wall plugs and screws.
- Well-thought-out connection: equipped with detachable cable entry and detachable plug-in terminal.
Applications
This measuring probe is intended for HVAC and building management applications where temperature on a surface is used as an input for control. Think of a technical installation in which a controller needs a temperature value to monitor or control the process. As a cable probe, the Sensor position can be adapted to the available mounting space.
The PR25 series can also be relevant when renovating control systems. Always check the existing Sensor element, the required connection method and the conditions at the installation location. For alternatives within the range, also see our temperature sensors and duct sensors.

Yes. The technical data lists protection rating IP65. The housing is of type USE-S and has a hinged lid.
What is included in the delivery?
The scope of delivery includes a mounting base for the USE-S housing and a mounting set with wall plugs and screws.
What should I pay attention to when replacing an existing Sensor?
First compare the Sensor element used, the connection, the required cable version and the installation location with the existing installation. If in doubt, contact us for advice.
Why choose Betec Controls?
When replacing a component in an existing system, a similar product name alone is not sufficient. Betec Controls therefore helps you compare article number 616386, the NTC1.8k Sensor element and the available installation data with the current situation. This enables you to choose a suitable successor or replacement version more consciously. Do you have photos, controller data or additional questions? contact Betec Controls for technical advice.
