High-sensitivity accelerometer B12A53

uniaxialpiezoelectricIEPE

Product Overview
Uniaxial IEPE industrial accelerometer B12A53 designed for high-sensitivity vibration measurement. Sensitivity 10000 mV/g and measurement range ±0.5 g make it suitable for low-level vibration and modal analysis. Stainless steel housing with laser-welded IP68 sealing and wide temperature range −40 to 85 °C.
