9402
Applications for Rochester Sensors's Guided Wave Radar Fuel Level Sender
Application
The 9402 series guided wave radar (gwr, gen ii) transmitter provides technical advantages over traditional reed switch probe liquid level sensors. The 9402 gwr sensor utilizes digital technology and requires minimal maintenance, while providing high accuracy measurements in mechanically challenging tanks. It features an anodized aluminum header and a stainless-steel waveguide. The wetted components are suitable for a range of fluids including diesel, biodiesel, synthetic oils, mineral oils, coolants, water, and mildly acidic or corrosive media. The 9402 sensor is highly configurable and can be customized for specific applications, including the selection of probe length and electrical outputs. The device is designed for stationary applications and is ideal for fuel monitoring for remote backup generators, particularly for tanks with pre-existing small access ports. The low-profile head design extends less than 1″ above the tank, and the side cable exit eliminates vertical clearance concerns for industrial systems.
