Acquire data from MEMS sensors with the Q.series X A108-4M1 and A108-2M3 I/O module
MEMS (Micro Electromechanical System) sensors are often used for low-frequency vibration measurements down to DC. These MEMS, also called K-Beam sensors, require a supply voltage for operation. The new Q.series X A107 and A108 module provides the sensor supply for convenient and straightforward setups. It is possible to connect up to 4 single-axis MEMS sensors to the A107-4M1 and A108-4M1.
The A107-4M1 comes with standard DSUB 9-pole while the A108-4M1 module comes with standard 1/4-28 sockets (type Comtronic female, 4-pole). Furthermore, two tri-axis MEMS sensors can be connected to the A108-2M3 module via its DSUB 9-pole (female) sockets.
The A107-4M1, A108-4M1 and the A108-2M3 provide a galvanically isolated sensor supply voltage of +15 VDC a sample rate of 20 kHz per channel. While the four inputs of the A107-4M1 are differential, the sensor input types of the A108-4M1/2M3 are software selectable as either differential and single-ended. These A108 modules provide a single-ended input per sensor input that can be used, e.g., for temperature compensation. With this feature, measurement setups of the highest accuracy are possible.
