See DetailsAs we all know, pressure gauges are consumables, common, and commonly used, so choosing a good pressure gauge manufacturer is crucial. However, the price of diaphragm pressure gauge pressure gauge varies between different manufacturers. Diaphragm pressure gauge adopts an indirect measurement structure, suitable for measuring the pressure of liquids and gases with high viscosity, easy to crystallize, corrosive, high temperature, and granular solid media. The isolation diaphragm has a variety of materials to adapt to a variety of different corrosive media. The next step is to introduce you to the diaphragm pressure gauge price-related factors are?
Demonstration value requirements
The pressure gauge is not pressurized and the instrument is in the working position, the zero value of the pointer error must meet the following requirements: the pressure gauge has a zero limit stop nail, the limit stop nail should be close to the pressure gauge pointer, should be in the basic error of the absolute value of the allowable range of ‘shrinkage’, shall not be exceeded. Allowable basic error and the accuracy level of the pressure gauge must be by the following provisions: that is, when the pressure gauge is not dynamic measurement, the absolute value of the allowable basic error must be greater than the return error. Similarly, in the static measurement, the absolute value of the allowable basic error must be greater than the value of the pointer in the case of the amount of change in the value of the tap. When the seismic diaphragm pressure gauge is for measurement, the dial or pointer in the full index range shall not appear to stagnation and jump phenomenon, and should always remain stable.
Appearance requirements
After the seismic diaphragm pressure gauge is manufactured, it should be ensured that each component is firmly assembled, and the exposed visible part should be smooth without obvious scratches or defects. Should be by the requirements of the standard use and operation of the seismic diaphragm pressure gauge, to avoid damage and defects caused by the repair and use of the phenomenon of measuring performance is seriously affected. Evenly distributed dial index scale and complete and clear dial index symbols and numbers are qualified seismic diaphragm pressure gauge basic requirements. The pointer-type pressure gauge should be a pointer in all the index lines should be reached, a small index interval of 1/5 should be greater than the width of the pointer indicator end, 1-3mm for the index dial plane spacing, and pointer interval range. Under the premise that the seal is not damaged, the internal mechanism of the seismic diaphragm pressure gauge should be kept out of reach of the sealing device as far as possible.
Seismic performance
When the seismic diaphragm pressure gauge is in the measurement, the pressure gauge itself is often subject to external influences and vibration. The vibration of the seismic diaphragm pressure gauge is generally divided into the working environment vibration and working medium pulsation. Working medium pulsation, pulsation pressure for the load, the seismic diaphragm pressure gauge should meet the following requirements: pressure reduction ratio that is the actual input pulsation load amplitude and seismic diaphragm pressure gauge disc or pointer swing amplitude ratio, the value is less than 0.5, in the verification of damping adjustable pressure gauge, the reduction ratio should be less than 0.5, and the reduction ratio shall not be changed during the calibration, the calibration of the work in a specific The calibration work can be carried out on the specific amplitude reduction ratio to meet the special requirements put forward by the user unit. When the working environment vibration, the allowable basic error is twice the error range of the pointer value of the seismic diaphragm pressure gauge and must have the following limitations: 0.15mm amplitude; 10-60Hz vibration frequency; the seismic diaphragm pressure gauge to carry 50%-60% of the applied load.
Through the above, you should have a more intuitive understanding of the factors affecting the price of a diaphragm pressure gauge. Therefore, you must find the right manufacturer when buying diaphragm pressure gauges, to buy the desired diaphragm pressure gauge.
