The Signet 9900 Transmitter provides a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen, and other sensors that output a 4 to 20 mA signal.  The 9900-1P Transmitter can also be used as a Batch Controller when a Batch Module and Relay Module are installed.

The 9900 is offered in both panel or field mount versions. Both configurations offer an extra-large (3.90” x 3.90”) auto-sensing backlit display features “at-a-glance” visibility that can be viewed at 4-5 times the distance over traditional transmitters.  The highly illuminated display and large characters reduce the risk of misreading or misinterpreting the displayed values.  The display shows separate lines for units, main and secondary measurements as well as a “dial-type” digital bar graph.

The 9900 can run on 12 to 32 VDC power (24 VDC nominal), and can also be loop powered with compatible sensors.

Rear Enclosure kits are available for the 9900-1P Panel Mount.  Kit options include either a Hinged Cover (3-9900.399-1) for wall or pipe mount installations or a Flat Cover (3-9900.399-2) designed to fi t inside a panel for waterproof protection.  

The 9900 offers complete flexibility, plug-in modules allow the unit to easily adapt to meet changing customer needs.  Optional modules include the new Modbus as well as the Relay, Direct Conductivity/Resistivity, H COMM, Batch, 4 to 20 mA Output, 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 of measure and decimal location choices.
