New Pressure Sensor 221-8859HE02 For Caterpillar Excavator 

Product description Hydraulic high-pressure sensors are used to monitor and measure key parameters in hydraulic systems, including pressure, temperature, flow and liquid levels. There are different types of hydraulic high pressure sensors, each with its own unique capabilities and characteristics. 1. Pressure sensors - These sensors measure the pressure of the hydraulic fluid in the system. They can be divided into absolute pressure sensors and gauge pressure sensors. Absolute pressure sensors measure pressure relative to vacuum, while gauge pressure sensors measure pressure relative to atmospheric pressure. Temperature sensors - These sensors measure the temperature of the hydraulic fluid in the system. They can be contact or non-contact sensors and can be mounted directly on hydraulic components. Flow sensors - These sensors measure the flow of hydraulic fluid in the system. They can be volume flow sensors or mass flow sensors for applications such as hydraulic pumps, v…
