Il termistore di temperatura del tallone della serie MF5A-4 è realizzato con rivestimento in resina epossidica e cavo isolante smaltato . il suo piccolo tallone min.1.1 mm lo consente risposta rapida. il filo smaltato ha un diametro esterno piccolo come 0.25 mm o 0.3 mm e il carattere di isolamento lo rende particolarmente adatto per ambienti di installazione ristretti come i misuratori di precisione . disponibile da una precisione generale dell'1% a una precisione superiore allo 0.2% e una tolleranza libera del 5% .
RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device. It does not produce an output on its own. External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage. Typically 1 mA or less measuring current, 5 mA maximum without the risk of self-heating.
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.
Il termistore NTC di precisione serie FHD4513 di focusens è realizzato con filo smaltato e ha un corpo di dimensioni minime che si adattano bene a misuratori di temperatura di piccole dimensioni.
