YTXC-100-Z 、YTXC-150-Z can bear the media pulse, impact and vibration. It is used to measure pressure of gas and liquid which has no corrosive affect for copper or copper alloy. There are upper limit and lower limit contact device. When the pressure achieve the setting value, it will send signal and cut off the control circuit for working system to auto-control or send signal. The anti-vibration structure can effectively suppress a pointer jitter, impact and protect contacts to make sure the normal working. It is widely used in mechanical, chemical, petroleum, metallurgy, electric power and other industrial processes。
