Function: Conversion of an input frequency to a linearly proportional output current or voltage. The MIN200 can be used to monitor the speed of rotating machinery and can be followed by a MIN100/MIN120 trip amplifier to give alarm, control or shutdown facilities at preset levels of speed. It is ideally suited for use with turbine flow meters to give an analogue measurement of flow rate, and with proximity detectors for non-contact speed measurement. The MIN200 incorporates both a sensitivity adjustment and a variable reference voltage to allow a variety of sensor types to be used.

Function: Isolating signal converter which will convert from a frequency range to an analogue output. The MicroFREQ F-A is a microprocessor based signal converter and can therefore be programmed by the user to specify the input and output frequency type and ranges. Both the input and output stages of the instruments are powered from separate secondaries of the transformer thus maintaining 3 port isolation. The MicroFREQ F-A has the programming function resident in memory.

Connect the MicroFREQ F-A to a terminal or PC via a Lee-Dickens MicroLEAD and change the input and output ranges as required.

Function: Precision electronic mains powered instrument for the integration of electrical quantities against time giving a 24 Volt DC pulse and an open collector output suitable for operation of an electro-mechanical impulse counter, etc. The MIN400 can be used for any application where time-varying signals require integrating. For instance:- Flow, Mass Flow (Liquids, Solids or Gases), Electric Charge, etc.
