What is a Height Gauge?

Height gauge is a commonly used measuring tool, which is widely used in construction, engineering, geological exploration and other fields. It can accurately measure the height of an object and is widely used in various measurement tasks. In this article ATO Store will introduce the composition, characteristics, working principle and its application of height gauge.

Composition of Height Gauge

An altimeter is usually composed of an altimeter host, an altimeter rod and altimeter accessories. The altimeter mainframe is the core component and contains components such as the range sensor, display and data processor. The altimeter bar is a rod-like object used to support and operate the altimeter mainframe. Altimeter accessories include fixed base, support frame, etc., used to fix and stabilize the altimeter main body.

The Working Principle and Process of Height Gauge

Working Principle

The height gauge mainly realizes the measurement through the principle of laser ranging. First of all, the main body of the altimeter emits a laser beam, which is sent out from the emission port of the main body of the altimeter. The laser beam propagates in the air and reflects when it meets the surface of an object. Then, the altimeter host receives the reflected laser beam and measures the round-trip time of the laser beam through the range sensor to calculate the distance between the object and the altimeter.

Working Process

The working process of altimeter can be divided into three steps: laser emission, laser reception and data processing.

1. Laser Emission: The altimeter host controls the laser switch to emit a laser beam that propagates at the speed of light in the air until it encounters the surface of an object.
2. Laser Reception: When the laser beam encounters the surface of an object, reflection occurs. The altimeter host receives the reflected laser beam through the receiver and converts the received laser signal into an electrical signal.
3. Data Processing: The altimeter host measures the round trip time of the laser beam through the range sensor and calculates the distance between the object and the altimeter according to the propagation speed of light in the air. Then the altimeter host will measure the results through the display.

Features of Height Gauge

1. High precision: Altimeter general length error in about 2μm, repeatability in about 0.5-1μm.
2. Low cost: The price of a three-standard measuring instrument is more than one hundred thousand or even millions of dollars, while an altimeter is only about 2-8 million. And maintenance costs are also lower, in the absence of conditions equipped with CMM, choose to buy height gauge can check most of the dimensional tolerances of the workpiece, is a cost-effective, flexible and convenient measurement program.
3. Reliable and durable: An altimeter can be used for more than 5 or 6 years if it is well maintained to maintain good accuracy without repair.
4. Easy to operate: Even inexperienced personnel only need half a day's training to operate the altimeter.
5. The altimeter can measure the distance of various objects (without reflector).
6. Increase the light filter can measure the high temperature of the measured body.
7. Visible light is easy to align the measured body.
8. Altimeter has external synchronization input.

Application of Height Gauge

Height gauge has the features of high precision, wide measuring range, easy operation, etc. It is widely used in construction, engineering, geological exploration and other fields.

1. Construction Field: height gauge can be used to measure the height of buildings, such as buildings, cranes and so on. By measuring the height of the building, you can carry out building design and construction work.
2. Engineering Field: height gauge can also be used to measure the height of engineering equipment, such as bridges, tunnels, etc. By measuring the height of engineering equipment, you can ensure the safe operation of engineering equipment.
3. Geological Exploration: height gauge can be applied to measure the height of geological features, such as mountain peaks, rivers by measuring the height of geological features, you can understand the characteristics and distribution of geological features.

In short, height gauge is a measuring tool that can accurately measure the height of an object. It realizes measurement through the principle of laser ranging and is widely used in construction, engineering, geological exploration and other fields. The working principle of height gauge is simple and clear, easy to operate, with high precision and wide applicability. In practical application, we can choose the right height gauge according to the specific needs, and correctly use the height gauge to carry out the measurement work, in order to ensure the accuracy and reliability of the measurement results.
