The Georg Fischer Signet 9900 Field Mount Display (3-9900-1) is a high-performance
multi-parameter transmitter and display unit designed for industrial process monitoring and
automation applications. Engineered by Georg Fischer, the 9900 transmitter provides a
single-channel interface capable of monitoring multiple process parameters including flow,
pH/ORP, conductivity, resistivity, salinity, pressure, temperature, level, dissolved oxygen, and
other 4–20 mA sensor signals.
The large auto-sensing backlit display delivers excellent visibility even in demanding industrial
environments, allowing operators to monitor critical process values from a greater distance. Its
intuitive interface, digital bar graph display, customizable labels, and modular expandability
make it ideal for process automation systems requiring reliable monitoring and control.
Designed for field mounting applications, the 3-9900-1 offers rugged construction, IP65/NEMA
4X environmental protection, and flexible integration with various industrial sensors and
communication modules.
