3200 Series Pressure Sensor for Forklift Trucks

June 17, 2021

As companies are growing due to increased demand for their products (including those that are mostly online), their warehouses are getting bigger, and the need for more and more forklifts grows. Forklifts are the Number One tool used in warehousing to move products from one location to another.

Operating a forklift can be challenging, as operators must move items of varying sizes and weights. As the load that the forklift picks up elevates into the air, the forklift can become unsteady, leading to a tip over and possibly injuring an employee.

One method of monitoring the load is to install pressure sensors into the hydraulic system of the forklift. As a heavy load is picked up by the forklift, the pressure sensors detect this change and send feedback to the controller/operator to indicate if the load's weight, height, and angle of the forks are within safe limits. The forklift can then automatically slow down and/or alert the operator that a change is necessary to restore a safe condition.

Challenge

Finding a pressure sensor that can hold up to a high number of pressure cycles, as well as over-proof (over-pressure) protection.

The demand for forklifts is required to run multiple shifts, operate constantly, and more frequently. The sensor must be able to withstand millions of operating cycles reliably. The sensor will also need to withstand sudden pressure spikes, as well as heavy shock and vibration from loads shifting while items are being moved around the warehouse.

Solution

3200 Series Pressure Sensors

The Gems 3200 Series pressure sensors are the heavy-duty versions of the standard 3100 Series pressure transducers. As the forklift gets bumped around the warehouse or outside loading vehicles, the sensor will be able to withstand everything that it is exposed to.

Additionally, every push and pull on the operating levers as the forklifts move up and down, tilt back and forth, and shift side to side, the pressure in the hydraulic system fluctuates through a high number of cycles. The 3200 series pressure sensor has been designed to withstand over 100 million cycles of operation, ensuring a stable output and long life operation.
