Analog Monitor ANA-3

Analog Monitor is used in all the plants where continuous measurements and monitoring of the alarm states are needed. In addition to analog values, digital alarm states can also be monitored. Analog monitors accepts direct connection from measuring sensors with 0(4) -20mA current output, or 0-10V voltage output, or resistive sensors e.g. Pt-100 temperature sensors, without additional transducers, as well as moisture and temperature sensors STH-3. The Analog Monitor can be mounted in a panel.

The application of microprocessor technology ensures fulfillment of the most demanding requirements regarding accuracy, reliability and availability of Analog Monitors in process or power plants.
