Delivery: ex stock | Warranty: 24 months Miniature Ring Load Cell MODEL 8438 Highlights M easuring ranges from 0 ... 100 N up to 0 ... 200 kN C ontinuous centric internal hole measured to fit F lat disc design P rotection class IP65 C ompletely welded sensor body I nternal thread in the bottom for fixing Options b urster TEDS S tandardization of the nominal sensitivity V arious cable lengths available C ustomization of geometry possible Applications F orce monitoring during riveting M easuring contact forces in hydraulic stamps M onitoring pulling forces during wire production M onitoring of forces in prestressed concrete structure Product description Medium measuring ranges Small measuring ranges The force to be measured must be introduced axially and perpendicularly to the entire surface of the inner and outer bands of the sensor in the opposite direction. Conversion of the acting force into an electrical output signal is performed by strain gages connected together in a full bridge circuit. To achieve optimal accuracy, the base of the sensor should rest on a smooth level surface, hardened to at least ≥ 58 HRC with sufficient dimensions. The base cover welded to the surface has a stabilizing effect on the sensor element. Lateral forces must be avoided anyway as they distort the measured results. Tension and bending relief for the sensor cable is to be carried out on the machine side. burster Sensors and Process Instruments – Technical changes reserved. All data sheets at www.burster.co

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. Our website contains details of suitable instrumentation amplifiers, indicator and display devices and process instruments. burster TEDS TEDSI The "burster Transducer Electronic Data Sheet" (TEDS) is a memory in which identification data of the sensor, calibration data and other sensor parameters are saved. In conjunction with your own suitable burster device, there is the option of performing a simple...
