The PA3 Series is a miniature high performance load cell constructed of heat treated stainless steel. The PA3 is designed to accurately measure compression forces in capacities ranging from 0-100 LB to 0-50,000 LB. The diaphragm sensing design, coupled with an enhanced strain gage arrangement, produces excellent performance in a very low profile, compact package. The inherent low deflection of the PA3 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. The integral premium instrumentation grade cable features a durable Teflon® jacket over a tinned-copper braided shield for superior mechanical protection and for minimizing the unwanted electrical effects of RFI and EMI. The attributes of the PA3 make it ideal for measurements in the laboratory, structural testing, materials testing, and general force measurements where a miniature, low profile precision load cell solution is required.
