Overview
The
PL9700
digital on-board weighing system consists of a digital indicator, load cells, transmitters, and cables
designed for on-board, straight, semi, roll-off, refuse and logging trucks.
Benefits of using the
PL9700
include:
•
Flexibility to read individual axle weights
•
A reliable two-wire hookup between the transmitters and the indicator
•
An extremely bright weight display, visible even in bright sunlight
•
Ability to calibrate the indicator without having to load the truck
•
A unique load-hold feature, useful when loading at several different sites
•
Measurements in increments of 10, 20, 50, or 100 pounds or kilograms
•
Internal software that can be updated to include the latest enhancements
A modern on-board weighing system consists of load cells to sense the load’s weight, transmitters and cables to
send the load-cell output to the indicator, and an indicator to change the signals into information usable by the
operator.
Load cells are precision-machined high-strength steel beams with strain gages bonded inside. The load cell is
installed on the truck between the load receiving deck and the truck frame. When loads are applied to the truck,
the strain gages sense the weight of the load and send a small electrical signal to the indicator by way of the
transmitter.
The transmitter provides the voltage to the load cell to power the strain gages. A signal voltage from the load cell
is returned to the transmitter where it is converted to a digital signal before being sent to the
PL9700
indicator
through the two-wire cable.
