Indicator / panel meter STR551 is designed for process acquisition and retransmission via analogue output.
Brand : Pixsys
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 program the device using the intuitive interface with multi-language text menus of the MyPixsys App thanks to integrated NFC communication.
