Model C904 Clinometer Pak 420

The Clinometer Pak 420 is the packaged version of our Tulip 4-20 mA clinometer. Its rugged aluminum enclosure provides mechanical and environmental protection for indoor or outdoor use. This uniaxial instrument is current loop-powered, so measurements can be made over long cables using an economical 2-wire pair. It also measures temperature using a built-in thermistor. Use it to monitor the angular position of conveyers, booms, ramps, and machinery; perform antenna tilt error corrections; and track the pitch and roll of ships, buoys, ROVs, and towfish.
