Delivery: ex stock | Warranty: 24 months Press Load Cell for hand and automatic operated presses MODEL 8451 Highlights Measuring ranges from 0 … 500 N up to 0 … 100 kN Non-linearity < 0,25 % F.S. Protection class IP65 / IP67 Simplest mounting on press ram Robust construction with mechanical overload protection Applications Forces in component joining Press-fitting Bending forces during material deformation Cutting forces when severing materia Forces during stamping processes Punching forces for blanks Break-out forces used in destructive testing Measuring ranges 0 ... 50 kN up to 0 ... 100 kN Product description The Load cell model 8451 has been developed for measuring the forces that occur during press operation. The internal measuring elements have a rugged design, which mean they can cope reliably with the steep force curves that are typical of press applications. They can be fitted or replaced quickly and easily on the press ram without the need for additional components around them. The force sensor is placed between the tool and the press ram and can thus measure the actual compression force directly in the axis of operation. The load cell measures the compression forces between the circular contact surfaces of plunger and tool. The pin on its top side and hole on its lower face are simply provided for mechanical fixing and centering the components correctly. The connecting cables are suitable for drag chains, designed for many movements and stably fastened in the sensor housing. Attachments are available which clamp onto the press sensors to enable easy mounting of displacement sensors according to the circumstances of use. burster Sensors and Process Instruments – Technical changes reserved.

Electrical termination Output signal burster load cells are based on a strain-gage Wheatstone bridge. This measurement principle means that the output voltage mV/V is highly dependent on the sensor supply voltage.
