1.0 Overview
The PL9710 digital on-board weighing system consists of a digital indicator, load cells, transmitters, and cables
designed for a variety of truck operations.
Benefits of using the PL9710 include:
• Flexibility to read individual axle weights
• A reliable two-wire hookup between the transmitters and the indicator or an optional wireless hookup
• An extremely bright weight display, visible even in bright sunlight
• Ability to calibrate the indicator without having to have the truck loaded
• 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 log load and the truck frame. When the logs are loaded on the truck, the strain
gages sense the weight of the logs 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
PL9710 indicator through
the two-wire cable or a wireless signal.
