Attention items:
The installation position should be close to the middle of the car cage as possible as it can.
The square porcelain steel with pasted paper is the working surface, and it should be opposite
to the transducer.
If there’s no voltage outputting after installation, please try to change the polarity of the square
porcelain steel.
3.7.1 The relationship chart between the distance (mm) from
top of the weighing transducer to
the square porcelain steel and transducer’s outputting voltage (V):
Fig 3-37 Weighing sensor’s outputting voltage
User can choose the best install distance according to the car cage’s compression
deformation from no load to full load and choose the maximum distance from it.
For example: If one customer’s compression deformation is 5mm, the user can analyze
according to chart9-7-3: ①、If the distance of no load is 21mm, and the sensor’s outputting
voltage is 5.25V, wh
en the distance of full load is 16mm, sensor’s outputting voltage will be
8.25V, and the change of the voltage from no load to full load is 3V. ②、If the distance of no
load is 35mm, and the sensor’s outputting voltage is 1.75V, when the distance of full load is
30mm, sensor’s outputting voltage will be 2.5V, and the change of the voltage from no load to
full load is 0.75V. Through the analysis of
① and ② we can conclude that the resolution ration
of ① is 4 times than that of ②. Obviously the higher resolution ration is, the better it will be.
