STR551 | Indicator -Panel meter 96x48

Indicator / panel meter STR551  is designed for process acquisition and retransmission via analogue output.

The monochrome OLED graphical display supports process trend displays with programmable sampling time and bar-graph representation with thresholds typically used for level, flow and dosage measurements.

Analogue input is configurable by parameter for a wide range of temperature sensors and process signals in mA and volts. Linearization is customizable up to a maximum of 16 points, useful on irregularly profiled tanks.

Process-related mathematical functions such as Totalizer and Sum are also implemented.

Connectivity is provided by standard RS485 with Modbus RTU/Slave protocol.

For maximum flexibility of use, there is also a choice of horizontal or vertical installation. 

User can choose among different programming options: the intuitive interface with multi-language text menus, the MyPixsys App thanks to integrated NFC communication, or the LabSofView software.
