Temperature Sensor

NTC Surface Temperature Sensor / optimal heat transfer and short reaction time / Tmax 250°C / robust ceramic housing / easy connection technology / fast and safe assembly / combinable with Thermostat, SOD or thermal link

Product is available on request

SmartySense sensors facilitate and optimize the assembly of NTC sensor elements. A key development goal was a time-saving, but safe and reliable installation of the sensor on the surface of heating elements.

SmartySense sensors have a tried-and-tested, temperature-resistant ceramic housing and standardized plug-in connections. The optimal thermal coupling and low heat transfer resistance ensure short response times and improved process control.

Depending on the application, SmartySense sensors can be configured as a single or combination product, with either a thermostat, thermal link or SOD.
