Height gauge
A height measuring device is a measuring device that is used either to determine the height of objects or to mark objects to be processed.
These measuring tools are used in metalworking or metrology to set or measure vertical distances. The sharpened pointer can act as a scriber when marking workpieces .
In principle, similar devices with reduced accuracy are used in health facilities ( hospitals , doctor's offices ) to measure the body size of patients and are referred to as stadiometers in this context.
Height gauges can also measure the height of an object by using the bottom of the scriber as a reference. The reference point can be permanently fixed or the height measuring device can have a device for adjusting the scale . The latter is done by moving the scale vertically along the body of the height measuring device by turning a fine feed spindle on the top of the measuring device. If the scriber is then placed on the same level as the base, the scale can be adjusted to it. This enables the use of different scriber pins or measuring heads, as well as adjustment in the event of errors caused by a damaged or re-ground measuring head.
In the tool room, a height measuring device and an area measuring device are distinguished in that a height measuring device has a measuring head ( vernier , rack with dial or glass scale with digital display), while a manometer only has a scriber. Both are typically used on a surface plate and have a heavy base with an exactly flat, smooth underside.
