The security door can be made of different materials, but only the door that meets the standard test and receives the production permit for the security product can be called the security door.
The principle of capacitive type sensor is to use positive and negative probes filled with liquid medium to form a linear change with the liquid level, the change of capacitance (that is, the change of liquid level) into a standard electrical signal output. The core components of the product use highly integrated special capacitance measurement chip, through accurate temperature compensation and linear correction, with high precision, high stability and continuous measurement advantages, with a strong independence. We provide customers several capacitive oil level sensors to meet your needs. You can choose one product according your medium, range, output signal and etc. We also provide OEM services, you can get your suitable products if you have special requirements of the products.
