El sensor de temperatura de la serie KTY es una solución de detección de temperatura simple y económica para condiciones generales que no tienen alta temperatura y humedad.
El sensor de temperatura NTC de alta precisión de la serie FHR400 se usa específicamente para aplicaciones médicas que monitorean la temperatura corporal . compatible con todos los equipos de monitoreo de sensores de la serie YSI 400 aceptados. como GE, HP, Japan photoelectric, philips, siemens, mindray, Treasure Wright Monitor, etc.
This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. They're often used to detect when a door or drawer is open, which is why they have mounting tabs and screws.
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.
