Accurate Frequency, RPM, Pulse Measurement

News

MMS Electronics, a UK-based supplier of display and sensor products, has introduced a new range of universal frequency to digital transducers (UFDC, USTI and USTI-EXT). These 2-channel converters work with any sensors from frequency-time signal domain group and convert frequency, period, its ratio and difference, duty-cycle, duty-off factor, PWM, time interval, pulse width and space, rotation speed, pulse number and phase shift to a digital signal.

The programmable accuracy UFDC-1 is 1 to 0.001 % and USTI (1 to 0.0005 %) in a wide frequency range; UFDC-1 up to 7.5MHz and USTI up to 9MHz (120/144 MHz with pre-scaling). The UFDC can work in 16 measuring and one generating modes (USTI 29 measuring modes). The USTI can also measure analogue and resistive sensor signals.

There are three serial interfaces: RS232 (including a master communication mode), I2C and SPI, and the small package size allows the converter to be designed within a sensor.
