Product Description

Model P84AS is an IEPE single axial accelerometer with static and dynamic response, this feature permitting the measurement of motion with high frequency and low frequency signal, even down to 0Hz(static) measurement. P84AS utilizes a silicon Micro-Electro Mechanical System (MEMS) sensor which exhibits excellent output stability over time. The accelerometer incorporates an internal circuit in a two-wire IEPE system which transmits the acceleration output through the same cable that supplies the constant current power. Polarity inversion protection for the amplify circuit is inherent in the circuit design. The accelerometer offer rugged, laser welded, stainless steel housing with durable military style connectors. Electrical case isolation, hermetic sealing, RF, EMI, ESD, and overload protection all ensure tolerance against environmental influence and mishandling. All variations provide reliable measurements and long-term stability. P84AS has ¼-28 threaded holes for stud mounting on the test object. Senther’s model 16A-L is a breakout cable for the sensor
