Intrinsically-Safe Frequency Calibrator
For the measurement of revolutions as well as calibration and testing of flow-meters, rotary piston meters, turbine meters and oval gear meters etc. in the hazardous area.
Operating mode
- Predetermining / measuring frequency
- Predetermining / measuring pulses
- Measuring/simulating number of revolutions
- Testing NAMUR-initiators
- Predetermining/measuring times
- Transmitting/measuring static levels
The FCX2000 offers a simple and quick means of measuring and simulating frequencies, pulses, numbers of revolutions, digital process signals and levels. The operator guidance with the help of a 4- Iine LCD-display and membrane keyboard allows simple and easy to use adjustment of all operator functions.
lt is possible to predetermine and measure NAMUR- signals according to DIN 19234 as well as static logic levels in hazardous locations, ranging from 0.01 Hz to 10 kHz with duty factors from 1 to 99 %. Accurate numbers of revolutions can either be measured by NAMUR initiators or by an optional external probe. For measuring revolutions on rotating machinery with the probe a suitable reflection mark needs to be attached. A visible beam of red light from the probe is then trained on this reflective mark.
An important function for flow-metering is the FCX2000 in the mode "pulse pre-determining" or "pulse measuring". Here pulse length and pulse pause will be predetermined first, before a fixed programmed number of pulses is released. The display in this mode shows, what percentage of the programmed pulses have been sent. Whether a two conductor NAMUR-initiator works properly or is malfunctioning can be checked by another function.
The intrinsically safe FCX2000 is supplied with standard rechargeable batteries. These are easily removed, but any recharging must be done outside the hazardous area. An integral battery level indicator shows when the batteries are becoming exhausted, so that enough reserve operating time is ensured.
The lightweight metal housings designed to ensure that the electronic parts of the FCX2000 are well protected so that the equipment can be used safely and with confidence under the harshest of industrial conditions.
