13 Operation
During normal operation VP Series 2000 field devices maintain their connection to the wireless
network and publish vibration and temperature measurements.
In addition devices monitor their own status, perform measurements and publish parameters as
configured.
13.1 Measurements
VP Series 2000 sensors perform various measurements on acquired signals. These include:
• Temperature
o °C
o °F
• Vibration
o g rms
o g pk
o m/s
2
rms
o m/s
2
pk
• Velocity
o mm/s rms
o mm/s pk
o in/s rms
o in/s pk
13.1.1 Temperature
VP Series 2000 sensors measure surface contact temperature by means of a temperature sensor in
the sensor base. The temperature can be scaled in degrees Celsius (°C) or degrees Fahrenheit (°F).
Refer to the product data sheet for temperature range and resolution.
13.1.2 Acceleration
VP Series 2000 sensors measure single or tri-axial vibration up to ±20 g (peak) by means of a
piezoelectric ceramic sensing element in the sensor base. The measurement accuracy is ±5% and
transverse sensitivity is typically 7%. Vibration measurements can be scaled as follows:
• g rms
• g pk
• m/s
2
rms
• m/s
2
pk
Refer to the product data sheet for acceleration range.
13.1.3 Velocity
VP Series 2000 sensors measure single or tri-axial velocity derived from the vibration signal. Velocity
measurements can be scaled as follows:
