Complete Protection from burning of winding     Thermo System Thermistors are manufactured in accordance with DIN 44081 and 44082. In three phase motors, one Thermistor should be embedded in each phase. Good thermal coupling between Thermistor and winding is essential. The resistance increases sharply in the region of the nominal response temperature. Because the PTC assemblies are very small and rugged, they can be located in compact locations where protec­tion is needed, such as directly inside the motor wind­ings and can withstand standard varnish dip and bake operations and other handling. Response times ≤ 5 sec. are achieved with THERMO SYSTEM Thermistor.           Features:     Provides economical and reliable protection for 3-phase motors Wide range available: 60°C to 190°C switching temperature Available in compact size for easy assembly into windings Rapid response protection for electrical machines Long hysteresis free switch cycle life. Steep temperature-resistance curve characteristic allows for   simple evaluation electronics.           Resistance-temperature diagram and main characteristics in accrodance to DIN 44081/44082     Thermo System motor protection sensors conform to DIN 44081 or 44082 and are characterised by very high temperature sensitivity. In the range of the nominal alternating temperature the resistance increases sharply. This change can be used by a relay to disconnect the load circuit. Electronic evaluation circuits in widely varying applications are also possible. The resistance temperature diagram shows the typical characteristics of the Thermo System PTC. Load must not be applied to the thermistors as this creates a self-heating effect. At ambient temperature the resistance value of thermistors is normally between 30 and 250 Ω. At ambient temperature the resistance values have no relevance to the serviceability (functionality) at the ROT (rated operating temperature).The ROT of PTC-thermistors in the range of +60°C to +190°C progresses normally in steps of 10 K.

Insta Control's PTC Thermistor offers protection against: Single Phasing Under/ Over voltage Continuous overloading Intermittent duty or Excessive start/ stops Insufficient ventilation or Excessive ambient temperature Mechanical jamming/ Overloading Bearing failure Our PTC Thermistors are manufactured in accordance with the international standards DIN 44081, 44082 andBS EN 60034-11:2004. Due to their small thermal mass, they have favorable temperature sensitivity.Insta PTC Thermistors should be placed as near as possible to the hot spot. In three phase motors, one PTC Thermistor should be embedded in each phase. Good thermal contact between PTC Thermistor and winding is essential. The PTC Thermistors should be embeded parallel to the winding. In this way the mechanical stresses on the PTC Thermistors during forming the end turns of overhang winding can be minimized. Shrink cap is especially well suited for this because of its mechanical stability. At ambient temperature, resistance of one thermistor is between 20 ohms to 250 ohms. The resistance increases sharply in the region of the nominal response temperature. Response times < 5 sec. are achieved with Insta Thermistor.This signal can be used to switch off power circuit of electric motors/ transformers by using Insta's Thermistor Protection Unit. Insta can supply customised connections with customised individual lead lengths, cross-sectional areas, crimped contacts etc.

PTC stands for "Positive Temperature Coefficient". PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. PTC thermistors have a non-linear resistance/temperature response, and at a specified temperature the resistance changes rapidly to a very high value. PTC thermistors act as thermal protection for electrical machines, and are well known particularly as motor-protectors. We are manufacturing PTC Thermistors as per international standards DIN 44081, 44082 and BS EN 60034-11:2004.   They are available with or without insulating sleeve and have flexible connecting leads. Many electrical motor & generator manufacturers are using Our PTC sensors.We can supply PTC thermistors with customized connections and leads as per customer requirements. We are manufacturing Simples as well as Triplex PTCs. Their Compact size makes them easy to use for assembly into windings.

Senso-Therm Control Solutions is dealing in a wide range of ptc thermistors from India.

Ptc Thermistor, Slipring, Terminal Box, Air Vent

PTC thermistors can also be used for monitoring changes in environment such as liquid level sensing, air flow indication and as current limiters. These thermistors cannot normally be used directly in series with the relay, hence it is recommended to employ an associated sensing or trigger circuit to operate a relay or thyristor circuit.
