Product details

The GF Signet 9900 transmitter is a highly flexible device that allows for interface with a variety of sensors to measure different parameters, including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, and others that output a 4 to 20 mA signal. It offers an extra-large display, measuring 3.90″ x 3.90″ and featuring auto-sensing backlit visibility, making it easy to read even from a distance of 4-5 times over traditional transmitters. The highly illuminated display and large characters reduce the risk of misreading or misinterpreting the displayed values.

The GF Signet 9900 transmitter is available in both panel or field mount versions, making it a versatile option for various applications. It can run on 12 to 32 VDC power, with a nominal voltage of 24 VDC. The device can also be loop powered with compatible sensors, offering an energy-efficient option.

Designed for complete flexibility, the GF Signet 9900 transmitter also offers plug-in modules that allow the unit to easily adapt to meet changing customer needs. Optional modules include Relay, Direct Conductivity/Resistivity, H COMM, and a PC COMM configuration tool. The unit can be used with default values for quick and easy programming or can be customized with labeling, adjustable minimum and maximum dial settings, and unit and decimal measurement choices, providing additional flexibility to users.
