Die hochpräzisen NTC-Temperatursensoren der Focusens FHR400-Serie werden speziell für medizinische Patientenanwendungen verwendet Körpertemperatur Überwachung . Es ist kompatibel mit allen gängigen Sensorüberwachungsgeräten der YSI 400-Serie. wie GE, HP, Japan Photoelectric, Philips, Siemens, Mindray, Treasure Wright Monitor, etc.
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.
