Sensors are widely used in daily life and industrial production, especially in China's "Made in China 2025" policy, which marks the country's transition from "Made in China" to "Made in China". At that time, life and production are destined to be more intelligent. In an intelligent life, sensors are bound to have a wider range of applications. In the market, due to the first mover advantage of the Industrial Revolution, Europe, America, and Japan started researching sensors decades earlier than China. Therefore, imported sensors and related products generally have much better performance than domestic ones, but the resulting prices are also much higher.

So how much does an imported sensor usually cost? In fact, sensors are a general term for products that can convert detected physical quantities into electrical signals. According to the measured physical quantities, there are pressure sensors, liquid level sensors, grating sensors, humidity sensors, force sensors, etc., which can reach more than ten or twenty types, and the price of each sensor is different; In addition, there are also many brands of sensors abroad, and the prices of different brands vary greatly, so it is difficult to have an accurate number.

For example, the grating ruler widely used in the machine tool industry has a price of 300 yuan in the homepage products searched on Alibaba, while in similar foreign products such as Heidenhain's grating ruler products, based on our 19 years of experience at Haier, the price is generally around 4000 to 4500 yuan, so the gap is still significant.

Although there is a significant price gap between sensors domestically and internationally, this has given domestic companies the determination to overcome difficulties and catch up.
