GF Signet 9900 Multi-Parameter Panel Mount Transmitter - Universal
4-20mA Sensor Interface
Product Introduction
The GF Signet 9900 Multi-Parameter Transmitter is a versatile
single-channel interface designed to integrate with a wide range of
sensors, including flow rate, pH/ORP, conductivity/resistivity,
salinity, pressure, temperature, liquid level, and any 4-20mA
output devices. Featuring a super-large 3.90" x 3.90" auto-sensing
backlit display, it offers panoramic visibility—4 to 5 times
clearer than traditional transmitters—with high-brightness
characters and dial-style digital bar charts to minimize reading
errors. Available in panel-mounted or field-mounted configurations,
the transmitter operates on 12-32VDC power (standard 24VDC) and
supports loop-powered operation via compatible sensors, making it
ideal for industrial process monitoring and control systems.
