Weighing instrument technique parameters of the basic definition and function

Abstract: the weighing instrument technique parameters of the basic definition and function of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1. Load rating: sensor can measure within the prescribed scope of technical indicators of zui big axial load. But the actual when using, normally just 2/3 ~ 1/3 of the nominal range. （ 2) Allows the use of load ( Or safety overload) : weighing sensors allows zui large shaft. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a weighing instrument technique parameters of the basic definition and function of the article details. 1. Load rating: sensor can measure within the prescribed scope of technical indicators of zui big axial load. But the actual when using, normally just 2/3 ~ 1/3 of the nominal range. （ 2) Allows the use of load ( Or safety overload) : weighing sensors allows exert zui big axial load. Allowed within a certain range overload. General is 120% ~ 150%. （ 3) Ultimate load ( Or overload limit) : weighing sensor can afford not to its incapacity zui big axial load. Meaning when work more than this value, the sensor will be damaged. （ 4) Sensitivity: the ratio of the output increment and the load increment. Usually each input 1 v voltage rated output of mV. （ 5) Nonlinear: this is the voltage signal of the sensor output and load of the corresponding relationship between accuracy of parameters. （ 6) Repeatability: repetitive characterization of sensor in the same load ShiJiaShi repeatedly under the same conditions, the output value can repeat, this feature is more important, more can reflect the quality of the sensor. National standard of repeatability error: the expression of nonlinear simultaneous determination repeatability error and three times on the same site measurement zui big difference between actual output values ( mv） 。 （ 7) Lag: the lag of the popular means: step by step of load and unload load in turn, corresponding to each level load, and ideally should have the same reading, but the truth is consistent, the index of the extent of the disparity with lag error. National standard of the calculated hysteretic so: three times on the same site visit actual output signal value arithmetic average and 3 times on the stroke of the actual values of the output signal of the zui big difference between arithmetic average ( mv） 。 （ 8) Creep and creep recovery: requirements from the two aspects of testing sensor creep error: one is the creep: in 5 - No impact on the 10 seconds time to add the rated load, 5 - after loading The 10 seconds reading, and then according to certain time interval in 30 minutes, in turn, take notes on the output value. Secondly, creep recovery: remove the rated load (as soon as possible In the 5 - Within 10 seconds) And in 5 - after unloading Reading immediately for 10 seconds, and then according to certain time interval in 30 minutes, in turn, take notes on the output value. Technical parameters of the weighing instrument technical indicators unit multichannel input 0 - as follows 0-20 mv single-channel output 20 mv precision & le; ± 0. 1% f。 S 12, 24 VDC power supply voltage - operating temperature More than 20 ~ 85 ℃ degree of protection IP65 is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

Clouds of v shape coriolis mass flow meter failures surround the world of tuning fork liquid density meter in particular, simply because people don’t pay as much attention to the mass flow meter as they should do.
