The Jewell Instruments C904 Clinometer Pak 420 Inclinometer 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, ROV's and towfish.
