Smartec UTI Sensor to Digital Transducer, DIL
The Smartec Universal Transducer Interface (UTI) is a complete analog front end for low frequency measurement applications, based on a period-modulated oscillator. Sensing elements can be directly connected to the UTI without the need for extra electronics. Only a single reference component, of the same kind as the sensor is required. The UTI outputs a microcontroller compatible period-modulated signal. The transducer can measure very accurately capacitance, platinum resistors, thermistors and resistive bridges. To accelerate sensor design with the SMT UTI an evaluation board SMT TOOLKIT is available.
