Dual sensor -- NTC thermistor temperature senor for medical application
Dual sensor -- NTC thermistor temperature senor for medical application

the dual sensor is assembled by 2 pieces of high precision and high reliable chips via shunt circuit method for health monitor

Medical Temperature Sensor with Dual Sensors:

FEATURES:

Higher reliability and safety

Excellent thermal cycle endurance

Tolerance of both chips up to ± 0.1°C

Parallel connection provides two circuit measuring channels

Mutually tolerance checked and can prevent the circuit measuring from losing efficacy. (the one circuit still works when the other loses efficacy.)

APPLICATION:

For making medical temperature sensor with top quality (monitor with top quality), e.g.: Skine / Coelom Temperature Sensor.
