Frequency to current/voltage converter
introduced
A frequency to current/voltage converter with built-in isolation and a universal DC power supply enables legacy pulse emitting devices to communicate with new equipment via A or V inputs.
Instrumentation specialist Lee-Dickens, has released a frequency to current/voltage converter with built-in isolation and a universal DC power supply that enables legacy pulse emitting devices to communicate with new equipment requiring current or voltage inputs The BM200 can be configured for use with a wide variety of transducers that produce a pulse or sine wave output

Conditioner family handles 'smart' digital signals
Signal conditioning modules, the Beta series, have been up-rated by Lee-Dickens to accommodate the 'smart' digital signals used by protocols such as HART.
DIN-rail mounted trip amplifiers score on size
Lee-Dickens has added two DIN-rail mounted trip amplifiers to its Beta range of products at a size and cost that improves on anything else currently available.
The unit converts the input signal into an industry standard isolated mA current or voltage output.
Because the BM200 produces an isolated output, it enables frequency-to-current/voltage-conversion without the worry of earth loop problems.
The BM200 is ideal for use with proximity sensors for non-contact speed measurement or monitoring the speed of rotating machinery such as turbine flow meters that give an analogue measurement of flow rate.
The unit can be used in conjunction with a Lee-Dickens BM100/BM120 trip amplifier to give alarm, control or shutdown facilities at preset levels of speed.
The BM200 incorporates both a sensitivity adjustment (a potentiometer located behind the fascia of the instrument).and a reference voltage to allow a variety of sensor types.
The DIN rail mountable BM200 has either 2- or 3-wire inputs and accepts an input frequency range of between 0 and 20kHz.
It has a universal DC power supply of between 8 and 30V.
The unit operates in a temperature range of 0 to 45 deg C.
