5/4/2021, · Hydraulic pressure switches are also designed to handle different pressure levels. A typical hydraulic pressure switch operates between 300-2600 PSI, although higher levels of 4000 PSI and even up to 12000 PSI are available at greater cost. Average temperature ranges are between -20 degress Fahrenheit and 160 degrees Fahrenheit.

What is hydraulic pressure? How is it measured? - Quora

Hydraulic pressure is, the force imparted per unit area of a liquid on the surfaces which it has contact., Liquids are incompressible, and as such, when a load acts upon it, the force is immediately transmitted to the contact surface. Hydraulic pressure is used in brakes, last decade power steerings, clutches, farm equipment, and most heavy machinery.
