Price of draw wire sensor
Purchasers of draw wire sensors will find that the price of this sensor varies from high to low. The main factors are:
Accuracy
The accuracy of the rope type displacement sensor affects its price in a large part. The higher the accuracy, the main component is the encoder. The better the encoder, the better the price. For the conventional 0.25% FS accuracy, the potentiometer is generally used, and the price will be much cheaper. However, based on the use of potentiometer, the price difference lies in the quality of potentiometer. There is a big difference in quality between a potentiometer，which is mainly reflected in the stability of performance and service life.
Material of pull rope
The pulling rope of most pulling rope displacement sensors is steel wire rope. Therefore, the quality of steel wire rope directly affects the wear resistance, anti-corrosion and rust prevention type, so it also directly affects its price. The SOP draw wire sensor uses the steel wire rope of KOSCO, which is not easy to break and can be used in the water environment.
Output signal
There are many kinds of output modes of the sensor. The draw wire sensor mainly has analog output: resistance output, voltage output, current output; There are also pulse output, digital output, etc. The price is different for different output modes. For example, the price of pulse and digital output must be higher than that of analog output.
