The Monad's Piezo-resistive Accelerometer consists of a Piezo-resistive MEMS sensor, a
semiconductor temperature sensor, and all of the necessary front-end signal conditioning which includes data acquisition, data processing and the IntelliBus-compliant digital bus.
It is packaged in a small, low profile metal case with two pig-tail connectors which are used for daisy chaining the IntelliBus-based network. Its low-noise front end signal conditioning and programmable gain allows for measurement of a wide range of vibration levels. Temperature readings from its built in sensor may be used for on- or off board temperature correction.
There are two software selectable 3-pole anti-aliasing filters. One with
a cut-off frequency at 2 kHz and the other at 360 Hz. The 16-bit A/D converter samples data at a programmable rate up to 250 ksps. A powerful processor performs digital signal processing algorithms such as digital filter, etc.
The Transducer Electronic Data Sheet stored in non-volatile memory provides the information needed to set up the highly versatile signal conditioner and data acquisition parameters.
