The ELM3244-0000 and ELM3246-0000 measure resistances very precisely in multiple measuring ranges up to 5 kΩ and are thus suitable e.g. for critical temperature measurements with high requirements. They can output the resistance value directly or transform it locally, depending on the set RTD characteristic (e.g. Pt100/Pt1000), into a temperature that is accurate to < ±0.05°C, depending on the type. The Beckhoff RTD measurement capability thus ranges from the simple EL320x through the precise EL320x-0010 up to the ELM324x. With a sampling rate of 1 ksps, they are part of the economy line and are suitable for observing comparatively slow processes that nevertheless need to be tracked very precisely.
Extensive documentation is available from Beckhoff sales, support or measurement@beckhoff.com.
This ELM3xxx series measurement terminal enables efficient implementation of complex system-integrated data acquisition systems (DAQ) that place high demands on measurement accuracy and time synchronization.
