Tedea Huntleigh / Model 1142 Single-Point Stainless Steel Load Cell

The stainless steel single point load cell model 1142 is designed for direct mounting with platform, bench and counting scales etc. The small physical size, combined with high accuracy and low cost, makes this load cell ideally suited for new or retro-fitted scales. OIML approved to C3 (20-100 kg) and NTEP approved to III/5000. A humidity-resistant protective coating assures stable operation in damp environments over the entire compensated range and conforms to IP66. For hazardous environments the 1142 load cell is available in EEx ia IIC T4 and ATEX 2G EEx ia IIC TA and FM level approved versions.
