Tedea Huntleigh / Model 1250 Aluminum High Capacity Single-Point Load Cell

The load cell model 1250 is an aluminum single-point load cell designed for direct mounting of large platform scales. The 1250 is a cost-effective load cell for use on counting, weighing, bench or floor scale products as well as in hanging scales and check weighing. These high accuracy load cells are OIML R60 and NTEP approved. The load cell has IP65 protection as standard but for wash-down protection an optional IP67 encapsulation protection is available. For use in hazardous environments the 1250 is available in an EEx ia IIC T4 approved version. FM approved to class I, II, III, Division I.
