The Georg Fischer Signet 9900 Field Mount Display (3-9900-1) is a versatile multi-parameter
transmitter and display unit designed for industrial process monitoring and automation
applications. Engineered by Georg Fischer Signet, this field-mounted transmitter supports
measurement and display of multiple process parameters including flow, pH/ORP, conductivity,
resistivity, salinity, pressure, temperature, level, dissolved oxygen, and other 4–20 mA sensor
inputs.
Featuring a large auto-sensing backlit LCD display, the 3-9900-1 offers excellent readability and
user-friendly operation in demanding industrial environments. The display includes a digital bar
graph, warning indicators, customizable labels, and intuitive menu navigation for simplified
monitoring and configuration. Its rugged NEMA 4X/IP65 enclosure ensures reliable performance
in harsh field conditions including moisture, dust, and chemical exposure.
Designed for direct field installation, the transmitter supports optional communication modules
such as Modbus RS485 and H COMM, enabling seamless integration with PLC, SCADA, and
industrial automation systems. Its modular architecture allows future expansion with relay,
batch, and conductivity modules for enhanced process control functionality.
