Belimo Surface Temperature Sensor Ni1000TK5000 - 01HT-1D
The Belimo surface temperature sensor is designed to measure water temperature in pipe applications via surface contact. The spring-loaded brass contact pin ensures a fast response and accurate temperature reading without the need to drill or interrupt the pipe. The passive Ni1000TK5000 element precisely converts the measured temperature into a resistance signal processed by the control system. Based on this measurement, the system is automatically regulated for consistent and efficient climate control.
Advantages and Features
- Ni1000TK5000 element: Passive resistance sensor with Ni1000TK5000 characteristic, compatible with controllers and BMS systems specifically configured for this sensor type.
- Spring-loaded brass contact pin: Provides permanent and stable contact with the pipe surface for quick and reliable temperature measurement, without the need to drill the pipe.
- Easy surface mounting: Installed on the outside of the pipe using a mounting strap, suitable for pipes with diameters from 20 to 110 mm.
- Housing with terminal block: Equipped with a protected connection chamber and plug-in terminals for secure and neat installation.
- IP54 protection class: Protected against dust and splashing water, suitable for use in technical rooms.
- Measurement range -35 to +90°C: Suitable for typical water and heating temperatures in HVAC systems.
Installation, Maintenance and Applications
The sensor is mounted on the outside of the pipe using the supplied mounting strap, suitable for pipe diameters ranging from 20 to 110 mm. For optimal measurement, the use of thermal conductive paste is strongly recommended to minimise the influence of ambient air on the reading. The housing allows for safe connection via a plug-in terminal block. Due to its passive design, no power supply is required. The sensor is used in commercial buildings, residential construction, and industrial HVAC systems for pipe temperature measurement without pipe modification.
Practical Information
The surface temperature sensor features a spring-loaded brass contact pin that maintains permanent contact with the pipe surface. The housing is made from impact-resistant, UV-resistant plastic and includes a cable gland with strain relief for a reliable connection. The Ni1000TK5000 element transmits the resistance signal directly to the controller. This sensor is ideal for pipe applications in heating, ventilation, and air conditioning installations where simple installation without pipe penetration is required.
