STS4 Flexible Surface Sensor for High Temperatures
Semitec flexible film NTC thermistor sensors are suitable for surface sensing applications up to 230°C. These springy “soft-touch” sensors use our FT or FL miniature thin film elements to achieve a very fast thermal response with a Tc of typically around 1 second. The highly sensitive thermistor elements are laminated between two high-grade polymer layers that give both robustness and high temperature thermal stability.
These soft-touch sensors were originally designed for use in laser-printers and multi-function photocopiers. However both catering appliances and industrial applications can also benefit from the fast thermal response combined with the high temperature stability offered by these sensors.
Applications
- Laser-printers
- Photocopiers
- Office automation
- Hot plates and appliances
Features
- Fast response design (Tc ≤ 1s)
