Details

Analog measurement variables are displayed, evaluated and calculated by the Endress+Hauser RIA46 field indicator. Two-wire sensors can be supplied with the integrated transmitter supply. The universal inputs allow the connection of current, voltage, RTDs and TCs. Limit values can be monitored and relays can be switched. Process signals can be transmitted via analogue outputs. Integrated "Differential pressure" application package for quick and easy commissioning in differential pressure applications.
