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:
