The PH3-A Series is a low profile high performance load cell constructed of heat treated stainless steel. The PH3-A is designed to accurately measure tension and compression forces in capacities ranging from 0-20K LB to 0-200K LB. The robust shear web sensing design, coupled with an enhanced strain gage arrangement, produces excellent performance in a low profile package that readily tolerates moments induced by angular, eccentric, or off-center loading with minimal sensitivity to these extraneous loads.The inherent low deflection of the PH3-A Series yields a high dynamic response and superior output resolution for a wide range of applications. This load cell is Harsh Environment Sealed (IP67-Limited Immersion) by virtue of proprietary multi-redundant barriers uniquely integrated to protect all internal components. A MS3112-10-6P (20K to 50K) or MS3102E-14S-6P (75K to 200K) connector is standard. Mating connectors with variety of cable lengths are available. The attributes of the PH3-A make it ideal for industrial applications as well as for measurements in the laboratory, structural testing, materials testing, and general force measurements where a low profile precision load cell solution is required.
