Function: Conversion of an input frequency to a linearly proportional, isolated output current or voltage. The BM200 can be used to monitor the speed of rotating machinery and can be followed by a BM100/BM120 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 BM200 incorporates both a sensitivity adjustment and a reference voltage to allow a variety of sensor types to be used.

Function: The BU191 is a universally powered Alarm Unit suitable for use with a number of different VA Flowmeters. It can be configured for use as a Low or a High Flow Alarm, as required. Each different VA Flowmeter will require a different sensor head for mechanical reasons but in all cases the operation of the Alarm Unit is the same. The sensor heads supplied come with 1M of cable for connection to the Alarm Unit. The BU191 has an “Instrument Fault” indication LED (Amber) which is triggered following loss of power or loss of connection to the Head. This LED can only be cleared by restoring power or replacing the head, passing the float from the Alarm State to the Healthy State and pressing the RESET button to initiate the Stable condition. The BU191 incorporates a sensitivity adjustment to cater for different VA Flowmeters.

Function: Isolating signal converter which will convert a range of process signals into standard transmission voltage or current signals. The BM303 first conditions the signal before feeding it through an opto-isolating circuit. Both the input and the output stages of the instrument are powered from separate secondaries of the inverter maintaining 3 port isolation.

Options include: a Signal Inverter, a Passive Output (Current Sink), Subtractor and an Adder or Averager. In the last three cases the inputs are restricted to mA or Voltage and the BM303 can only accept two inputs.
