Tedea Huntleigh / Model 240 Fluid-Damped Single-Point Load Cell

Model 240 is speciically designed to be used wherefast acquisition of a stable load signal is paramount. TheModel 240’s unique luid damping system allows the loadcell to be used in applications that previously required theuse of LVDT’s or similar types of measuring devices.The Model 240 brings load cell adaptability into checkweighing and grading applications.Approved to OIML R60 and NTEP standards, sealedto IP66 level and available in coated steel or stainlesssteel, the Model 240 is suitable for most wash-downapplications.The two additional sense wires feed back the voltagereaching the load cell. Complete compensation ofchanges in lead resistance due to temperature changeand/or cable extension, is achieved by feeding thisvoltage into the appropriate electronics.
