Application of Thermistors Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12322
Indian Lab Suppliers supplies the Application of Thermistors (Product ID: 12322) as part of its electronics engineering lab equipment range. It builds four temperature alarm and control circuits using NTC and PTC thermistors.
Quick Answer
The four experiments are a temperature or fire alarm and an over-temperature control alarm with an NTC thermistor, and a temperature or fire alarm and an under-temperature alarm with a PTC thermistor. Five op-amp ICs act as comparators, and two NPN and two PNP transistors drive a 12 V DC relay with two change-over contacts; a 6 V bulb shows when the relay is energised. The relay can switch a 100 W bulb (supplied with holder and 2-pin plug) plugged into the panel socket as the controlled load. The thermistors are warmed on a hot plate, which the buyer provides. The 100 W lamp circuit is at mains voltage and the hot plate and lamp get hot, so work under supervision.
