Cable temperature probe
Description
The TF-2000 cable temperature probe provides reliable temperature values for refrigeration technology, heating and heat pumps. Frequent changes between the dew point and the freezing point are not a problem - thanks to a measuring element that is completely overmoulded with plastic and is thus dust-tight and waterproof in accordance with IP68. Quick-mounting brackets enable time-saving installation. In addition, the thermometer can be mechanically stabilised using a stainless steel sleeve.
Special features
- Permanently protected against condensation
- Cost savings thanks to quick assembly
- Delivery reliability, even for large orders

| Dynamic behaviour per IEC/EN 60751 | |
|---|---|
| Response time | The response time is essentially influenced by the probe design, the heat transfer to the measuring element and the flow rate of the medium. |
| Due to the design of the model TF-2000, there is optimum heat transfer from the medium to the measuring element. | |
