LOADRITE SPRINT OPERATORS MANUAL

9 Specifications

Suitable Applications

The Loadrite measures weight by sensing the hydraulic pressure required
to lift a load. A trigger mechanism senses the position of the lifting arms.

Typical vehicles using the Loadrite system are:

•

Front end loaders (bucket and/or fork)

•

Forklift trucks.

Minimal Weighing Delay

Weighing delay is minimal, because the weighing function is carried out
during a normal lift. Loader should be stationary.

Power requirements

Supply Voltage

12 to 32 Volts DC

Supply current

Loadrite indicator: 160mA
typical, 350mA max.
Loadrite printer: 50mA standby,
4A peak.

Automatic transient suppression exceeds relevant SAE specifications
for DC automotive power supply transients.

Signal Inputs and Outputs

Pressure transducer input

1 - 20mA (0-100%).

Trigger input (Magnetic)

Pull up resistor requiring switch
to ground

Serial communications.

RS232C protocol to printer and
data logger

Display

LCD display

Back light

Keypad

6 keys

Back light. Special functions
