The SeaGauge AGW™ Sensor Interface Unit is a splash resistant unit that allows up to 2 engines and other vessel sensor data to be output on NMEA 2000®/J1939 CAN bus networks. Each Sensor Interface Units can handle up to 8 different inputs (2 Pulse, 6 analog). All inputs are calibrated using stored 256 point tables uploaded via USB interface The Sensor Interface Unit provides digital instrumentation for a variety of performance parameters such as tachometer, fuel flow, boost, rpm, oil pressure, engine temperature, fuel level, voltmeter, main and auxiliary battery, and much more all in a compact sealed design.
