KTY sensors, as well as PTC and NTC thermistors, are well suited as temperature sensors for many applications in the automation technology, in electronic components or in assemblies, in medical technology or in electrical machinery and equipment. Thanks to their compact size, they are ideally suited for installation in narrow copper windings of low voltage motors. In general PTC and NTC thermistors and silicon-based sensors (KTY type 83-1xx and 84-1xx) are the proven choice for thermal monitoring of electrical machines and motor protection. Motor protection thermistors are particularly...

09. MOTOR PROTECTION THERMISTORS PTC Combining a motor protection PTC thermistor with a switching device provides an effective, inexpensive and fast response solution for protecting electrical machines against overheating. PTC thermistors A positive temperature coefficient thermistor (PTC) is a semiconductor of endowed, polycrystalline barium titanate ceramic, whose electrical resistance rapidly increases when a certain temperature is exceeded. PTC thermistors available by EPHY-MESS are mainly motor protection thermistors according to DIN EN 44081 - 82 and already comply with the successor...

NTC thermistors are mainly used to monitor resistance changes over a wide temperature range. Because of the flexibility in their design NTC thermistors can be put to use in a wide range of environments with demanding design requirements. Miniature thermistors can be used in monitoring points only 1.5 mm wide. The NTC thermistor is a temperature dependent semiconductor resistor according to DIN EN 44070 respectively IEC 60593, whose resistance value decreases with increasing temperature - contrary to PTC thermistors. The negative temperature coefficient (NTC) is about -2 to -6% per kelvin...

KTY silicon sensors are devices with a semiconductor layer. They possess, similar to PTC thermistors, a positive temperature coefficient but in contrast they show an approximate linear characteristic. While handling or processing KTY sensors it is necessary to note that these components are sensitive to static electricity and their long-term behaviour can be damaged by ESD. Appropriate precautions (ESD protection) should be taken. KTY-SH axial KTY semiconductor sensor type KTY83-1xx KTY semiconductor sensor type KTY84-1xx Silicon sensors of the KTY series are diode-like semiconductors....
