Detector:Connects a load cell as the detector and it detects strainquantity.

Transmitter:(1) Detects minute output voltage which changes depending
on strain quantity.
(2) Converts the output voltage into digital signals andtransmits the signals to the Output Sensor.

Output Sensor :Converts the strain quantitiy data transmitted fromthe Transmitter into analog signals (4...20mA) andoutput it to external unit and supplies power for operationof the Transmitter.

◆ Use a regulated power supply, e.g. switch-model type.

Note
Please note that the cable length of an output sensor may not longer thanP7KH&(PDUNLQJYHUL¿HVWKDWRXUSURGXFWVFRPSO\ZLWKWKHUHTXLUHPHQWV
of EMC directive. The surge test to an output sensor is not carried out.
When using an output sensor with cable length longer than 10m, a measure
to protect the sensor from serge current should be taken.

Mutual interference
In order to prevent mutual interference between parallel-mounted
sensors, keep minimum spacing as described below;◆ Ensure correct connections by reference to the wiring diagram.
Zero balance
Since zero balance for output of load cell is not programmed inside,
it should be done outside.

◆ To avoid malfunction caused by induction noise, cable should
be kept apart from motor or other power cable.

A* Adjust load cell output to be 0mV at R1 or R2 (some hundreds kohm)
