Description

B1, B2, B3 are capacitive spring mass accelerometers with integrated sensor electronics. Resonant peaks are minimized by means of an special gas-dynamic damping in the primary transformer.

The sensors can be supplied with an analogous DC output, a digital pulse-width modulated signal or a frequency modulated output. The sensor electronics requires only a very low power consumption and is characterized by a high degree of long-term stability.

Application

The acceleration sensors B1, B2, B3 are typically used where, high overloading occur, high long-term stability are needed, where a very low frequency near to static signal are required and where very short rise-time and small power consumption is required.

Typical applications are:

Measurement on vehicles, machines, buildings, in process control systems as well as for safety installations
Seismic measurements
Inclination measurements
Dynamic measurements
Machine vibration measurement
Dynamic rate determination
