4. Product description
The SMT160-30 is a three terminal integrated temperature sensor, with a duty-cycle
output. Two terminals are used for the power supply of 5 Volts and the third terminal
carries the output signal. A duty cycle modulated output is used because this output is
interpretable by a micro-processor without A-D converter, while the analogue
information is still available.
The SMT160-30 (TO18 model) has an overall accuracy of 0.7 °C in the range from -30
C to +100 °C and an accuracy of 1.2 °C from
-45 to +130 °C. This makes the sensor especially useful in all applications where
"human" (climate control, food processing etc.) conditions are to be controlled.
The C-mos output of the sensor can handle cable length up to 20 meters. This makes the
SMT160-30 very useful in remote sensing and control applications.
