Hydraulic Motor Velocity Sensors Explained in Layman’s Terms

Hydraulic Motor Velocity Sensors Explained in Layman’s Terms

Hydraulic motors are finding their way into more and more places in recent many years and there is a very good explanation why. They are significantly a lot more compact and can create far more torque in a considerably smaller sized device. Electric and fuel driven motors are also noisy and make heat. Also, the two of these sorts of motors frequently demand some type of transmission technique to control torque.

The Issues of Large Stress Hydraulic Method

However hydraulic motors do have their very own shortcomings that have to be dealt with. For occasion, they call for a supply of large pressure hydraulic fluid be ran to them for the motor to run. Large strain hydraulic fluid offers its personal problems in handling and shifting it.

A Tightly Sealed Method

For instance, owing to the fact the a hydraulic motor is made up of and is run by higher force hydraulic fluid they need to have to be tightly sealed. This by nature prevents the use of a normal speed sensor that uses a cable that is linked to a equipment in the motor.

The Corridor Impact

So what is the response? hydraulic power machine is to use velocity sensors that use magnets to gage the velocity of a hydraulic engine from the exterior. So how can a magnet gage the pace of something? When an electrical recent is ran perpendicular to a magnet, the present will be effected when the magnet is in the existence of a ferrous metallic this sort of as iron or metal. Its referred to as the “Hall effect”

Counting Gear Tooth or Turbine Blades

So a magnetic sensor is used to count the rotations of a gear or a turbine blade that is in the hydraulic motor or the hydraulic fluid line. Each and every time a tooth of the equipment or a blade on the modest turbine passes the magnetic hydraulic motor pace sensor, an electric powered pulse is designed that is then sent by wire to a pace gage.
