Order note：
1：Please try to fully understand the pressure detection point of the media status, pressure range and other working conditions. To avoid the unnecessary losses caused by unreasonable use of the product.
2：Although the product has designed a variety of protection measures, but for extreme applications, such as the scene with strong lightning applications, should ensure that the power supply grounding, and install anti-lightning protection device to minimize the probability of product failure.
