Model 34 Precision Miniature Load Cell DESCRIPTION The Model 34 tension/compression load cell has female threads Model 34 precision miniature load cells measure both tension attachments. High accuracies of 0.15 % to 0.25 % full scale are and compression load forces of 1000 g to 1000 lb. These achieved. Each bonded strain gage unit is built of welded 17-4 models are our highest accuracy, rugged miniature load cells. PH stainless steel for additional ruggedness. All load cells with Model 34s welded, stainless steel construction is designed to ranges from 1 kg to 10 lb have an electrical balance module in eliminate or reduce to a minimum, the effects of off-axis loads. the lead wire (approximately 1 in x .087 in thick). This balance (The inter nal construction assures excellent long-ter m stability module does not have to be the same temperature as the for ranges 1000 grams and above.) A modification per mits this transducer. model to be completely welded for underwater applications.
