1.4 Instrument Description
The AquaTrend Interface provides a link between sensors and communication
devices. This networked system provides simplified use of multiple
instruments and requires fewer wiring configurations than systems without a
single digital wiring bus.
The AquaTrend Interface is available in three different physical configurations:
• AquaTrend Interface
• AquaTrend Interface with SOM
• Portable AquaTrend Interface
See section 2.2 , Device Descriptions on page 18 for additional information on
the different configurations.
1.4.1 Operating Environment
Place the AquaTrend Interface in an accessible location, where you can easily
see the display and operate the keypad. The backlit display is visible at 3 ft.
with multiple readings and at 10 ft. with single reading.
The AquaTrend Interface is designed to operate from 0 to 40 °C (32 to 104 °F)
and 5 to 95% relative humidity, non-condensing. The water-tight design meets
NEMA 4X (indoor) and IEC 529 IP66 enclosure requirements.
