New release - temperature monitoring relays TELE Haase
Share your knowledge
We’re annoucing a new release in our permanent offer of automation products from our renowned supplier TELE Haase - temperature monitoring relays .
Temperature monitoring relays play an important role in automation systems - they monitor critical physical values. Offered temperature monitoring relays have typically connected PTC sensors, which sharply increase their resistance after crossing a right temperature. They are used e.g. for protecting engine winding and transformers.
Our offer includes models of temperature monitoring relays V2TF01P and V2TF01.
Tele Haase company is an Austrian producer and expert in the category of time relays and electrical monitoring devices. Tele relays can be used in various applications, including converter stations, control cabinets and water, wind and solar power plants. Industrial electronics of time and monitoring Tele relays improves protection actions of the natural environment by supporting proper work of renewable energy sectors and waste management.
Temperature monitoring relay - how does it work
If the supply voltage U is applied and the cumulative resistance of the PTC-circuit is less than 3.6kΩ (standard temperature of the motor), the output relay R switches into on-position. When the cumulative resistance of the PTC-circuit exceeds 3.6kΩ, the output relay R switches into off-position. The output relay R switches into on-position again after the cumulative resistance falls below 1.6kΩ.
