Two entirely new sensors expand a family of lightweight low impedance, voltage mode accelerometers for OEM, multi-channel or general-purpose vibration measurements. Weighing only 4-grams, the Kistler 8774A50 and 8776A50 feature ceramic elements config-ured in a thermally stable K-SHEAR configuration, 100 mV/g sensitivity and low transverse sensitivity of 1.5%.

Types 8774A50 and 8776A50 have a measurement range of ±50g with a threshold of 0.0025 grms. The sensors are designed for high immunity to base strain and thermal transients. Powered from Kistler couplers, signal conditioners or any 2 to 20 mA constant current source, the 8774A50 and 8776A50 sensors feature high frequency response of 1 to 10 kHz and 1 to 7 kHz respectively. The accelerometers are hermetically sealed in a titanium case.
