|
| |
Features of
digital truck scales: |
|
| |
1. |
Numeral transformation technology and
compensation |
|
| |
a. |
The
Inner part of the weighing load cell contains
module conversion device and CPU processing
unit. |
|
| |
b. |
Auto-compensation with digital technology to the
parameter of load cell such as non-linearity,
temperature, etc. |
|
| |
c. |
Free
of calibrating for the scale if the load cells
are replaced. |
|
| |
2. |
With
the calibrating and digital technology,
bias-load (four corners) calibration of the
truck scale can be completed only once. |
|
| |
3. |
Digital communications technology |
|
| |
a. |
The
central line structure can be used by several
weighing load-cells (up to 32) in the same
system. |
|
| |
b. |
RS485 interface is used and long-distance signal
transmission is possible, with the transmission
distance not less than 1000m. |
|
| |
c. |
Output signal at 3~4V strengthens the capability
of anti-interference and lightening protection
of the system. |
|
| |
4. |
Intelligent technology |
|
| |
a. |
The
parameter of the load cell can be changed
according to the orders. |
|
| |
b. |
Different wave-filtering ways can be adopted
according to different situations. |
|
| |
5. |
Module, standard and series scale body,
multiunit assembly |
|
| |
6. |
Digital load cell of full-sealing column and
laser-welded stainless steel, with accuracy of
C3, strong water-proof and anti-corrosive
function |
