Infinity Pro keeps the measurement chain of Infinity and changes what sits around it. Three axes from DC to 6 kHz, a 26 kHz sampling rate and ±16 g are the same numbers; the difference is lower power consumption and a threaded stainless steel bottom plate.
That plate is the reason to choose it. A rigid metal coupling to the machine keeps the frequency response accurate where a plastic housing on a magnet begins to roll off, which matters when the fault you are chasing sits in the higher end of the band.
The thermometer reads -40 °C to +125 °C, the housing is IP67 and the operating range runs from -40 °C to +80 °C. The last pages carry the full tables for the sensor and for the Senseway gateway.
