Temperature Sensors with Magnetic Fixing

The temperature sensors are intended for contact temperature measurements of ferromagnetic materials. The contact with measuring surface is provided by springing of the measuring surface. The plastic connection head is provided with a cable outlet ending (the terminal board is placed in the connection head) or a connector. The standard operating temperature range is -30 to 100 °C. The sensors can be utilised for any control systems that are compatible with sensing element output signals or output signals quoted in the table of sensing element types.

The sensors are designed to be operated in a chemically non-aggressive environment.

*) The temperature sensor´s measurement error is dependent on the influence of ambient temperature, environmental variables and the characteristics of the measured surface (error of method).
**) It is recommended to apply heat-conducting paste or silicon grease to the measured surface, which will ensure faster response time and minimise the measurement error of the contact temperature sensor.
