HXC series is a low cost distance monitor USD 59 in hundreds. It
uses a wide beam transceiver, and is therefore less sensitive to the
orientation of the object. It is useful for position or level
measurements in cases where the objects are not necessarily flat and
orderly. And it may also be useful for liquid level measurement. The table below is a
general selection guide, if you don't find a device that suits your
application, let us know we can change the parameters.

The illustration below shows how the HXC converter
series can be applied. The brown wire is connected to a volt meter.
In case of the Distance to Voltage converters the voltage
is proportional to the distance or
- Voltage (brown wire) = (Vsupply * D)/(Max Distance)
In case of the Proximity to Voltage converters the
relationship is as follows
Voltage (brown wire) = Vsupply * (Max Distance - D) / (Max
Distance)
Where D is the distance between the reflecting surface and
the converter. Max Distance is as specified in the Distance to Voltage
converters, or Proximity to Voltage tables below

Beam Pattern
The sensor is located in the locus of the polar plot
shown below facing north, maximum signal strength is along the 0 degree
axis. As the observer with the measuring instruments moves east and west
i.e. perpendicular to the 0 line signal strength degrades. The beam
pattern character line shown below represents observation angles where
signal has degraded by 6 decibels.
