VF-500 Measuring / Switching ranges     

At the time of manufacture your sensor is scaled to provide the greatest possible resolution for your specific application i.e. the best useable data.

We have 3 standard ranges and these are shown below in Figures 1 and 2 (the information is the same in both but one is a diagrammatic representation and the other tabular).

Figure 1 diagrammatic shows the 3 available measuring and switching ranges

Key to which range to select

• If you will be using the sensor with the Fog Warning System to switch equipment and do not wish to send the output to a data logger then please select using the Fog Warning Switching Range.

  ---

• If you will be using the sensor to send data to a logger please select using the Total Measurement Range.

• If you will be using the sensor for both then please select the scale with the most suitable combination of both ranges.
  

NB In the measurement range 0.1 V - 0 V the signal resolution will be quite low and we would not recommend using the sensor within this range with a data logger or where the cable lengths are in excess of 328 ft. These ranges are indicated by the Low Signal Range (l l l l l l).

Figure 2 - the same information depicted in tabular format

This range is in continuous development therefore specifications may change without prior notice E&OE.
