Measured quantity

What the sensor measures: vibration acceleration (spectrum analysis, bearings), vibration velocity (condition assessment to ISO 10816/20816) or temperature.

Output type

AC (IEPE) — voltage vibration signal for analysers and online monitoring systems. 4–20 mA — loop-powered current signal for PLC/DCS/SCADA. Line Drive — current signal for analysers that support it.

Measuring range — velocity

Vibration velocity range corresponding to 4–20 mA, selected when ordering.

Connector

Integral cable

PUR — resistant to oil and abrasion. Braided — mechanical protection. FR — flame-retardant. HFFR — halogen-free (polyolefin). FEP/PTFE — high temperatures and chemicals.

IP rating

IP67 — temporary immersion, IP68 — continuous immersion (conditions specified by the manufacturer), IP65/IP66 — water jets.

Guides

IEPE accelerometer or 4–20 mA transmitter? A comparisonAn IEPE accelerometer delivers the full vibration signal for analysis, while a 4–20 mA transmitter delivers a single overall value to the PLC. We explain how both types work, how they differ and when a dual-output sensor is worth using.
