A laser displacement sensor, capacitance sensor and so on, the accuracy of various sensors are not the same, a millimeter, micron and even nanometer, ZLDS100 displacement sensor is the high precision displacement sensor arrived at the nanometer level.

　　Any product has the same level, the displacement sensor is divided into three, six, nine and so on, we should learn to use as a magnetoelastic sensor resolution level, of course, we must first understand the sensor applications we need to acquire,

　　As a buyer, of course, want to buy a moderate price, cost-effective, good quality products, the following describes the general difference in sensor level method

　　The accuracy of displacement sensor has two kinds of linear accuracy and repeatability accuracy

　　1, linear precision: linear precision position measurement system is of theoretical value and practice value of the error rate is a percentage of the contact. 2, repeat accuracy: refers to the maximum fault range measurement system several times in the same physical range when the output value of the,

　　The original is also expressed as a percentage, but it is not intuitive,

　　We use length fault to express, such as 0.01mm. level, I don't know whether it means IP protection level. I stands for sensor dust resistance, the highest level is 6.

　　P stands for sensor waterproof ability, the highest level is 8., sensors can generally do the protection level of IP65/66/67, the highest protection level is IP68.

　　Two, anti-interference ability, the general use of digital output quotes are expensive, because the digital output displacement sensor because it is only to collect digital output attack resistance small,

　　So anti-interference ability than analog output ability, quotation is relatively cheap

　　If we want to choose the best displacement sensor, we choose the linear precision, low repetition error and low error digital output magneto elastic sensor products
