Clear allWhat 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.
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.
