Focusens PTC thermistor is a leader in the field of motor protection with excellent quality. Its core feature is the sudden increase in resistance at critical temperature. It is high quality and low price, and performs well in heavy-duty motors. To avoid the risk of direct interruption of large currents, the PTC sensor intelligently monitors the temperature and provides high-resistance protection when exceeding the threshold, safely cutting off the circuit and preventing the motor from overheating.
il termometro digitale DS18B20 fornisce misurazioni della temperatura da 9 bit a 12 bit centigradi e dispone di una funzione di allarme con punti di attivazione superiore e inferiore non volatili programmabili dall'utente. il DS18B20 comunica su un bus a 1 filo che per definizione richiede solo una linea dati (e terra) per la comunicazione con un microprocessore centrale.

PTC Thermistor Focusens offers a comprehensive selection of motor protection, including our advanced thermistor probe PTC thermistors. These PTC thermistors, featuring an insulated wire cable, significantly increase resistance from a few hundred ohms to several thousand ohms at their thermal switching point (Ts). This sharp resistance change allows the PTC thermistor to function as a solid-state thermal switch, ideal for triggering electronic circuits to deactivate overloaded electric motors, overheated bearings, or electrical appliances. Choose from our range of PTC thermistors with temperature switch points from 60°C to 180°C to ensure optimal protection for your equipment.
