MS Electronics distributor of display and sensor products has made available the Universal Sensor and Transducer Interface (UFDC, USTI and USTI-EXT). The USTI can measure analogue sensor signals resistive) but also quasi-digital sensors.
Accurate fast sensor system and frequency measurement IC M
(capacitive and Quasi-digital sensors output the
sensor data in frequency, duty-cycle or PWM format. It has always been very challenging and time consuming to measure with a micro-controller the sensor signal as accurate as specified in the sensor specification. Often reducing the quality of the sensor reading. By using the USTI a high-resolution conversion is now available. Based on novel patented methods the USTI can measure frequency, period, pulse count, rpm rotation speed, frequency ratio, duty-cycle, frequency difference and phase-shift measurements with a relevant error of 0.0005%. The error is constant over the full input frequency from 0.05 Hz to 9 MHz or 144 MHz by using prescaling.
The USTI has serial, SPI and I²C
interface and can be used in slave or master mode. In addition to measuring quasi-digital sensors the USTI can interface to resistive, including platinum (Pt), cuprum (Cu) resistors, thermistors (Ni), resistive bridges and capacitive sensing elements. An extended temperature version USTI-EXT (-55 °C to + 150 °C) can be used directly in or near gearboxes, transfer cases, engines, turbochargers and exhaust systems. The USTI is available in various packages PDIP, TQFP and MLF. The small size allows the USTI to be designed within the sensor offering sensor designers increased resolution, programmable accuracy, TEDS and I2C, SPI and serial interface ports.
Frequency measurements An evaluation board based on the UFDC-1 is available for 2 channel accuarate frequency, rpm and other time-domein measurements. With this low cost evaluation board it is possible to make high accuracy measurements equal to expensive benchtop frequency meters The EVAL-UFDC board has an RS-232 serial port for control of the UFDC. Simple commands are used to set resulution, conversion speed, modes and start/stop the measurement.

With 160dB dynamic range - SIRIUS can find “a needle in a haystack”
very measurement engineer at some time has been faced with the dilemma of what measurement range to use to make sure all signals are captured with best resolution – but not anymore Using the very latest dual core ADC technology DEWESoft have been able to develop a new data acquisition system called SIRIUS which offers a range of input channel configurations, all with 1kV isolation and dual-core 24bit- 200kS/s ADC technology which means that the smallest and largest signals can be captured simultaneously without worrying about the input measurement range SIRIUS is available in 8 channel measurement slices, which can be expanded with additional modules to build a 32channel system with all channels synchronized
E With the addition of the i7 SBOX controller, the system becomes a fully
integrated measurement package capable of streaming all channels at maximum sample speed
SIRIUS includes DEWESoft measurement software Dewetron UK Ltd.
