STR561 | Strain-gauge indicator / Panel meter

STR561 indicator with strain-gauge input is designed as a display for load cells and Melt pressure transducers (mV/V) and includes isolated power supply for the strain-gauge.

Conversion frequency programmable up to 1.2 KHz and resolution up to 24bit ensure high accuracy.

Different analog input calibration modes are selectable (sample weight, percent full-scale value, mV/V value).

Software features worth mentioning include multiple options for Tare management, Totalizer , Sum functions, process trend display with programmable time base or bar-graph with alarm/event thresholds.

An auto-configuration mode has also been implemented for some  Dynisco Melt transducers, simplifying the settings required of the user.

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

STR561 interface is also quickly configurable via NFC with MyPixsys APP, without the need to power up the instrument or via multi-language text menus from the frontal keypad
