sensitive altimeter

sensitive altimeter

[′sen·səd·iv al′tim·əd·ər] (engineering) An aneroid altimeter constructed to respond to pressure changes (altitude changes) with a high degree of sensitivity; it contains two or more pointers to refer to different scales, calibrated in hundreds of feet, thousands of feet, and so on.

sensitive altimeter

A form of pneumatic altimeter that is more accurate than a simple altimeter. It has an adjustable barometric scale by which the instrument can be adjusted to the existing barometric pressure. The altimeter pointer makes a complete revolution for each thousand feet, with the second pointer indicating thousands of feet. The instrument, in addition, may have a counter reader to replace the third pointer, which indicates tens of thousands of feet.
