[Temperature – PTC–Si (KTY)]
PTC / Si (KTY)
Further information on this product is available in our newsletter "EinBlick".
Basic information
The low-cost KTY-sensor is used for precise temperature monitoring, control, and switching in windings, bearings, machines, motors, transformers and many other industrial applications, where errors in measurements have to be excluded.
Application
With outstanding accuracy and fail-safe operation, they have a wide range of applications in both automotive and industrial markets.
Industrial applications:
- Overheating protection
- Protection for power supplies
- Process temperature control
- Exhaust control
- Toaster control
- Temperature compensation for microprocessors
Automotive applications:
- Oil temperature
- Oil level
- Water temperature
- Diesel injection
- Transmission
- Engine coolant
- Engine air
- Air condition
General function
The silicon temperature sensors in the KTY84-1 series have a nearly linear, positive temperature coefficient of resistance over the complete wide temperature range.
Advantages of there sensors
- low cost over a temperature range: -40 ... +300°C
- larger output signal than Pt100
- very long operation life
- high long term stability
- low weight
- low thermal time constant
