Vehicle test stands are subject to extreme conditions. The vehicles inspected can weigh up to several tons. To ensure that they remain safe during testing, they are secured with safety chains. These chains need to be constantly monitored to ensure the safety of people and equipment.

The force measurement system consists of four force sensors and an electronic control unit. The force sensors are integrated into the safety chain through the use of ankle bracelets and drag rings, from where they send signals to the control unit.

The FN3002 force sensor is suitable for test bench applications and can be used in a variety of harsh environments. It measures tension and pressure in standard ranges from 0-10kN to 0-1000kN, and its mechanical design and strain gauge layout minimize lateral effects. Depending on the range, the FN3002 uses aluminum alloy or stainless steel construction and offers a variety of options.
