Technical Reference
Example 4 - Distance Measurement
This mode of operation may be used for equipment position monitoring up to 60 m (200 ft).
Operation is similar to Space Measurement operation except that measurements are
referenced to the transducer face.
For this example we’ll assume the following:
• Transducer 10 (an XLS-60) is mounted horizontally* facing the Tripper Car.
• when the Tripper Car is at the far end stop, the transducer face to Tripper Car
distance is 175 ft.
• when the Tripper Car is at the near end stop, the transducer face to Tripper Car
distance is 5 ft.
• the Tripper Car travels at 7 ft/min, and is normally maintained 14 ft from either
end stop.
• a mA output proportional to Tripper Car distance from the transducer is required
for PLC operation.
• if the PLC reads 3.8 mA, the Tripper Car is to immediately stop.
• an LU AO is connected to the SITRANS LU10 Peripheral Communications
terminals.
*When an XLS or XLT series transducer is mounted horizontally, install a support plate
under the transducer to prevent possible mounting/conduit connection damage.
