ELM3604-0002 | 4-channel IEPE analysis, 24 bit, 20 ksps, BNC

The ELM360x EtherCAT Terminals are designed for the evaluation of IEPE sensors (Integrated Electronics Piezo-Electric), which are mainly used for vibration diagnostics and acoustics. The constant current feed can be set to 0/2/4 mA. The input characteristics are also flexibly adjustable from DC to 10 Hz in the CoE. The ELM360x basically measures voltages AC/DC and in addition, the internal scaler function can be used if, for example, an output in acceleration [m/s²] is desired.

Irrespective of the signal configuration, all ELM modules have the same technological properties. The ELM360x modules for IEPE evaluation offer a maximum sampling rate of 20,000 or 50,000 samples per second. IEPE sensors are often connected via coaxial cables, therefore the ELM360x modules feature a BNC connector.

There are variants with factory calibration certificate and a recalibration service for the ELM series in preparation.
