Forklift Scale Leverages Hydraulic-Pressure Sensor to Weigh Loads

This forklift scale is claimed to be among the most accurate hydraulic scales on the market. The operator can activate the weighing scale by lifting load to the height of a magnetic sensor.

PRECISE Hi-Accuracy Forklift Scales, claimed by developer Keytroller to be among the most accurate hydraulic scales on the market, are controlled using a color LCD touchscreen powered (at 12 V dc) via the forklift vehicle. The operator can activate the weighing scale by lifting load to the height of a magnetic sensor.

The electronic manifold bypass module leverages a proportional solenoid valve along with a flow restrictor and hydraulic-pressure sensor to measure hydraulic pressure as oil flows past a pressure transducer. The sensor collects hundreds of pressure readings and filters out high and low pressure deviations to eliminate errors within 0.2% of the actual load.

Available at approximately half the cost of other competing scales, the array of forklift-scale models can handle loads under and above 10,000 lbs. They are water-resistant and designed to withstand tough, abusive applications. Watch the video below for a full rundown of PRECISE’s capabilities:
