The Endress+Hauser RIA45 Process Meter with Control Unit
Order #: Endress+Hauser RIA45 Process Meter with Control Unit
Analog measured values are indictated, evaluated and calculated by the process meter. With the integrated loop power supply two-wire sensors can be powered. The universal inputs enable the connection of current, voltage, RTDs and TCs. Limit values can be monitored and relays can be switched. Via analog outputs process signals can be forwarded. The integrated application package "differential pressure" allows the quick and easy commissioning for differential pressure applications.
