Thermal Sensors Moxie®
Thermal Sensor MOXIE®
Moxies are a family of, variable resistance thermal sensors having a highly specific “transition region.” Within this transition region the devices typically exhibit a negative temperature coefficient ranging from 40% per °C to 200% per °C. Below the transition region they exhibit a linear “thermistor” characteristic of -2 to -4%/°C.
