What role does the cutting machine cutting head sensors?

When cutting processing cutting machine equipment, how to accurately control the cutting head and the distance of the workpiece and verticality of the nozzle and the workpiece surface is very important.
Control is good or bad will directly affect the machining quality of cutting equipment, so in order to improve the cutting quality, reduce unnecessary loss, need some special sensors on cutting head installation to ensure the quality of its cutting can produce consistent, and can improve the safety of the production process.
the cutting head in the shape change of the workpiece and the surface is uneven, sensor automatically detects and according to the changes automatically adjust the height, make it consistent with the distance on the surface of the workpiece can always faster processing materials without having to continue to supervise, today is the capacitive displacement sensor are basically used at home and abroad, its structure and shape corresponding to the processing head, at the same time with a detection signal processing unit.
displacement measurement is a basic measurement, whether to contact with the workpiece to be measured in accordance with the sensor, displacement sensor can be divided into two types, contact and non-contact, compare with non-contact sensor and non-contact sensor in the guarantee of high resolution at the same time, with fast dynamic response and low hysteresis error, even to zero.
non-contact sensor, sometimes called close to the sensor, the application of the early years when close to switch, the tested object and sensitive probe close to a certain distance, the switching signal is given, the current close to the sensor have been developed to not only can detect the presence of object, and can give the object distance sensitive probe, and can provide information about the workpiece shape and space position, because it can be used to measure the displacement of moving object, so this kind of sensor is also known as non-contact displacement sensor, displacement sensor is commonly used with hysteresis expansion displacement sensors, electric eddy current displacement sensor, capacitive displacement sensor, inductance displacement sensor etc.
ZuoLong machinery is development and production of high-end equipment specialized factory.
After years of unremitting efforts, to create '' brand, the company has independent research and development and manufacture of welding machine, cutting machine, comprehensive development and production capacity.
