requirements of EN 61326.

Measurement Accuracy

■

Parameter - Typical

- RMS Velocity +/- 0.4 dB

(Corresponds to +/-4%)

- PeakVue +/- 0.4 dB

(Corresponds to +/- 4%)

- Temperature +/- 4° C

NOTE: (1) Measurement accuracy is the absolute accuracy of

the measurement relative to a known, calibrated excitation for

WirelessHART devices.

(2) Typical measurement accuracy represents the expected

performance operating under steady-state conditions (constant

temperature at 20°C with no external interference) for a mid-band

excitation (nominally 1 g at 100 Hz). This variation includes the

frequency response of the electronics and the sensor

Measurement Precision

■

Vibration: +/- 0.2 dB over 24 months

■

Temperature: +/- 2 °C over 24 months.

Self Calibration

■

The analog-to-digital measurement

circuitry automatically self-calibrates for

each update by comparing the dynamic

measurement to extremely stable and

accurate internal reference elements

Vibration Effect

■

No loss in functionality when tested per

the requirements of IEC60770-1 with

high vibration level (10 Hz to 10 Khz)

and up to 50g acceleration
