The Electronic Static Weigh-bridge is made up of
a framework of girders adequately reinforced with
transverse beams and suitable non-slip top deck
with Pit less & Pit type Structure. The entire
steel framework is mounted on strain gauge double
ended shear beam / Compression Type Load Cells (4,
6, & 8 No's. Load Cells), depending on length
of the platform. The shear stress produced by the
load is detected by a strain gauge, full bridge
circuit and converted into an analog electrical
signal. Signal from each loadcell is fed to Junction
Box. Output from Junction Box is fed to microprocessor
based weighbridge Microprocessor based weighbridge
Intelligent Terminal. The processing electronics
of terminal digitizers the signal from the Junction-box
using an ADC, based on time proven quad slope integration
technique and weight is registered on LED display.

Diffrence
Between Pit Type And Pitless Type Electronic Weighbridge.
|
|
Pit
|
Pitless
|
| Cost |
More expensive
due to additional construction work required |
Less expensive
due to less construction work |
| Service
and scale repairs |
In some cases,
more costly due to confined area restrictions |
Less Difficult
or costly and serviced from above |
| Clean
Out |
Done manually
and very time consuming |
Quick and
easy, done with a water hose or compressor
from the side |
| Scale
Inspection |
Must be performed
from inside the pit |
Can be performed
by simply walking around the perimeter of
the scale |
| Restrictions
or hazards |
Some states
require specified clearances underneath scale.
Must also deal with OSHA and confined space
hazards regulations. |
Some states
require specified clearances underneath scale |
