The model 910A is a comparison standard accelerometer designed specifically for accelerometer calibration. The unit is hermetically sealed and ideal for long term reference standard. This sensor is the industry standard for vibration/shock calibration. The model 910A provide Ultra-stability performance and flat high frequency response by reliable crystal sensing element. Model 910 offer double side(Top & Bottom) 1/4-28 thread hole for shaker mounting and the sensor under test. Features a button configuration, model 910A operating in compress mode. The specially designed crystal exhibit low base strain sensitivity and high resonance frequency, and excellent output stability over time. Signal ground is connected to the outer case of the unit, an insolation washer is available by option. The accelerometer features a 10-32 side connector and requires a coaxial cable for measurement operation. Senther’s model 11-3 is a 10-32 to BNC breakout coaxial cable for the sensor.
