Hydraulic Motor Speed Sensors Explained in Layman’s Phrases

Hydraulic motors are locating their way into much more and a lot more spots in latest many years and there is a good purpose why. They are far much more compact and can create a lot more torque in a considerably smaller sized sized device. Electric powered and gas run motors are also noisy and create heat. Also, each of these types of motors often call for some kind of transmission system to control torque.

The Issues of Substantial Pressure Hydraulic System

However hydraulic motors do have their very own shortcomings that have to be dealt with. For occasion, they call for a resource of substantial stress hydraulic fluid be ran to them for the motor to function. High pressure hydraulic fluid provides its own difficulties in dealing with and moving it.

hydraulic press supplier Sealed Method

For instance, because of to the reality the a hydraulic motor consists of and is powered by high pressure hydraulic fluid they need to be tightly sealed. This by nature stops the use of a regular speed sensor that makes use of a cable that is connected to a gear in the motor.

The Hall Result

So what is the reply? The reply is to use speed sensors that use magnets to gage the speed of a hydraulic motor from the outside. So how can a magnet gage the pace of some thing? When an electrical present is ran perpendicular to a magnet, the current will be effected when the magnet is in the existence of a ferrous metallic this kind of as iron or steel. Its named the “Hall result”

Counting Equipment Enamel or Turbine Blades

So a magnetic sensor is employed to rely 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 gear or a blade on the small turbine passes the magnetic hydraulic motor pace sensor, an electrical pulse is produced that is then sent by wire to a velocity gage.
