Jewell Model 901 & 902 Clinometer Description：

Datasheet Tulip Datasheet Outline Drawing

Model 901 (horizontal) and 902 (vertical) Uniaxial & Biaxial Clinometers accurately measure an angular position with the same performance as Model 900, but in a slim design for use where space is limited. High-gain, standard, and wide-angle versions are available, each with a different angular range. A901 and A902 (biaxial) use high-level voltage outputs to allow signals to be delivered over long cables. C901 and C902 – also referred to as ‘Tulip’ (uniaxial) are loop-powered, so measurements can be made using an economical 2-wire pair. These conveniently sized, low-cost units fit neatly into underwater pressure housings, well logging tools, drilling equipment, and many other devices.
