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.
