Le capteur de température de la série MFE-2 est un capteur de type encapsulation époxy. Les éléments NTC et RTD sont les éléments de détection les plus populaires. L'avantage particulier de la série MFE-2 est la réduction des coûts et la taille compacte.
Focusens MFP series HVAC averaging temperature sensor is exquisited designed for duct or pipe applications for air or water where accurate average temperature measurement is required. By using optimized sensing architecture, flexible sensing tube distribution across the airflow or pipe section, it provides a more representative temperature signal than a single-point sensor, especially in large ducts or uneven airflow conditions.
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.
The PTC thermistor mz6 series sensors are temperature sensitive, and positive temperature coefficient thermistors (PTCs) have higher resistance values at higher temperatures. They belong to semiconductor devices and can be used in series with a single or multiple motor protectors.
Ce capteur d'interrupteur de porte AT1315 est souvent utilisé pour détecter quand une porte ou un tiroir est ouvert, il a des pattes de montage et des trous pour se visser sur le mur de la porte. Les deux options de modèle de travail NO et NC sont disponibles.
