What the sensor measures: vibration acceleration (spectrum analysis, bearings), vibration velocity (condition assessment to ISO 10816/20816) or temperature.
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.
Vibration velocity range corresponding to 4–20 mA, selected when ordering.
Top exit — the cable leaves along the sensor axis (the most common option). Side exit — low profile: for tight spaces, guards, dust and dirt.
PUR — resistant to oil and abrasion. Braided — mechanical protection. FR — flame-retardant. HFFR — halogen-free (polyolefin). FEP/PTFE — high temperatures and chemicals.
Versions designed for hazardous areas. Certification details (category, group, temperature class, barriers) are given in the datasheet and the certificate.
As declared by the manufacturer in the product description. Current certificates are available in the documentation.
In the catalogue: −55 … +130 °C. Products whose range covers the values entered will be shown.
