Delivery: ex stock | Warranty: 24 months Miniature Ring Load Cell MODEL 8438 Highlights Measuring ranges from 0 ... 100 N up to 0 ... 200 kN Continuous centric internal hole measured to fit Flat disc design Protection class IP65 Completely welded sensor body Internal thread in the bottom for fixing Options burster TEDS Standardization of the nominal sensitivity Various cable lengths available Customization of geometry possible Applications Force monitoring during riveting Measuring contact forces in hydraulic stamps Monitoring pulling forces during wire production Monitoring 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

General tolerance of dimension Mounting Requirements for evenness of the mounting surfaces: 5 µm, Parallelism of the mounting surfaces: 20 µm. Surface hardness: ≥ 58 HRC. Mounting instructions Mounting: measuring range ≥ 0 ... 1000 N There are three mounting holes on the lower side of the sensor, equally spaced on T diameter with division 120°, one hole is located directly across the cable exit. This kind of mounting is allowed for compression load only burster Sensors and Process Instruments – Technical changes reserved. All dat

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.
