• Large auto-sensing backlit display offers highest visibility

Signet's 9900 universal-input transmitters provide a single-channel interface for a wide variety of parameters including pH/ORP, conductivity/resistivity, salinity, flow, pressure, temperature and level. Even 3rd party generic 4-20mA sensor signals can be displayed with the use of i-Go signal converter (sold separately). The large, auto-sensing display is readable at 4 to 5 times the distance of traditional transmitter displays, reducing the risk of misreading values.

The single-channel 9900 transmitter features a backlit display with separate lines for units as well as main and secondary measurements, plus a dial-type digital bar graph. It features two options for easy setup programming: simple full text-based menu via front panel buttons, or PC COMM Configuration software. Software option lets you customize labeling, min/max dial settings, and unit/decimal measurement choices using a Windows PC and the included USB connection tool. Optional plug-in modules let you easily adapt your transmitter to meet changing needs. Modules include relay (2 dry contact relays for panel-mount only), additional analog output, and H COMM (HART® Communication).

Panel-mount transmitters can be used with any standard 1/4 DIN enclosure or two custom options shown on facing page. Enclosure 21288 features a rear beveled hinged cover for NEMA 4X protection when wall or pipe mounted. Enclosure 21289 features a flat rear cover, and provides complete NEMA 4X protection to the rear of the transmitter when mounted inside a panel.
