Categories

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.

Sensitivity

Sensitivity of an AC accelerometer. 100 mV/g is the standard in vibration diagnostics; lower sensitivities are used for high vibration levels, higher ones for very low levels.

IP rating

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

Cable / connector exit

Top exit — the cable leaves along the sensor axis (the most common option). Side exit — low profile: for tight spaces, guards, dust and dirt.

Hazardous-area version

Versions designed for hazardous areas. Certification details (category, group, temperature class, barriers) are given in the datasheet and the certificate.

Intrinsically safe (Ex i)9

Approvals and certificates

As declared by the manufacturer in the product description. Current certificates are available in the documentation.

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.
