frequency current converter

XPZ-02 frequency current converter according to the frequency components can be converted into a linear 4 ~ 20mA constant current. Change its internal use of a dedicated chip, an increase in isolation between input and output, with closed-loop amplifier and FET composed of V/I conversion, and on the use of resistors, capacitors, a rigorous screening, so have a good constant flow characteristics, conversion accuracy is 0.2. It SZMB-5T magnetic speed sensors constitute the nuclear power plant cooling pump speed detection device.
