STR551 Digital Panel Meter with Bargraph
Digital Panel Meters STR551-AD for 4-20mA, 0-10V input signals
The indicator STR551 stands out in its market segment for the bright OLED display and the innovative multilingual interface as well for RFID/NFC connectivity. The analogue input can be configured by parameter for a wide range of temperature sensors and process signals in mA and Volts. The monochromatic OLED graphic display supports a large numeric display, graphs showing process trend with programmable sampling times and bar graphs with alarm thresholds typically used for level, flow and dosage visualization.
The linearization of input can be customized up to 16 points as required on tanks with irregular profile. Mathematical functions linked to process value are also available, such as Totalizer and Sum. Connectivity is guaranteed by RS485 with Modbus RTU/Slave protocol.
Numeric, Bargraph or Trend Display
Vertical or Horizontal Orientation
For maximum flexibility of use, it is also possible to choose between horizontal or vertical installation of the same device.
Distinctive feature of the entire STR series is the ability to configure and clone the device using an Android smartphone via RFID/NFC using the free MyPixsys smart phone APP from GooglePlay
