The Skin Temperature Probe contains a small biomedical chip thermistor. The thermistor is designed to operate from 0 to 50 °C. The Skin Temperature Probe MLT409/A is suitable for connection to the ML309 Thermistor Pod.


Operation:

The thermistor is a small, ceramic-encapsulated metal-oxide semiconductor. It exhibits a characteristic non-linear inverse relationship between resistance and temperature that allows its use as a temperature sensor. The relatively large change in resistance as a function of temperature (~ 4%/°C) gives a signal response far greater than thermocouples and resistance temperature devices (RTD). The probe is held flat against the skin of the subject and is usually taped into position. It can be cold-sterilized between subjects.

Application:

The Skin Temperature Probe is specifically designed for continuous biomedical temperature monitoring requiring repeatability, high sensitivity and rapid response
