ELM3602-0002 | 2-channel IEPE analysis, 24 bit, 50 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. In voltage measurement mode 12 different measurement ranges from ±20 mV to ±10 V and 0 to 20 V are adjustable.

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-0002 feature a BNC connector. The new 2-pin version with push-in (ELM360x-0000) on the other hand is ideal for industrial use where a plug is unplugged less frequently for maintenance purposes and fast wiring is much more important.

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