A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [ 1 ] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [ citation needed ] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on. The former type of height gauge is often used in doctor's surgeries to find the height of people. Wire gauge: measuring tool determines the thickness of a wire.
Solid thermometer principle: relation between temperature and length of a solid (coefficient of thermal expansion). Bimetallic strip; Thermistors principle: relation between temperature and electrical resistance of ceramics or polymers, range: from about 0.01 to 2,000 kelvins (−273.14 to 1,700 °C)
Depth gauge or height gauge. Form of marking gauge for marking lines parallel to an edge, by setting the head to a certain distance from the end of the rule. [6] Reference for directly transferring dimensions without needing to take a measurement, minimising measurement errors and inaccuracies. [7]
This style is widely used in construction work but not for more precise control work. An advantage is that one person can perform the levelling independently, whereas other types require one person at the instrument and one holding the rod. The sensor can be mounted on earth-moving machinery to allow automated grading.
A stadiometer is a piece of medical equipment used for measuring human height. It is usually constructed out of a ruler and a sliding horizontal headpiece which is adjusted to rest on the top of the head. [1] Stadiometers are used in routine medical examinations and also clinical tests and experiments.
Vernier caliper with a vernier constant of 0.1 for clarity of operation. The standard for a caliper is usually a constant of 0.02 Vernier caliper scale with the normal 0.02 vernier constant, showing measurement of object at 19.44 mm to two decimal places
For deep well designs, the Sealed Gauge measuring principle is also used. From a depth of approx. 20 m, the relative pressure can only be compensated to a limited extent by the thin hose. The level sensor is then designed as an absolute pressure transmitter whose zero point is adjusted to the desired mean air pressure depending on the location ...
