These transmitters convert pressure readings in harsh areas into electrical signals that are transmitted to a remote-control room or monitoring panel. Flush-tip transmitters have a stick-resistant coating that helps protect them from aggressive fluids. Birdcage transmitters have sensors that are shielded by a cage-style housing. These durable transmitters resist clogging and are commonly used for harsh applications in wastewater and slurries, chemical storage tanks, oil tanks, sumps, and sewage lift stations.
