Lowering Maintenance Expenses and Raising Efficiency of Concrete Pumps Using High Pressure Resistant Sensors

A double piston pump is used in concrete pumps. Two feed cylinders are required for this process. 

They pump the concrete at operating pressures up to 400 bar. These feed cylinders are propelled by hydraulic cylinders. 

Cylinder pairs operate in an opposing push-pull manner. The time of this push-pull action needs to be precisely synchronized to achieve maximum efficiency. 

It is crucial to monitor the cylinder end position using high-pressure resistant sensors.

What type of sensors can be the best suggestion?

High-pressure resistant sensors 

Some features of high-pressure sensors:

Resistant to pressures up to 1000 bar - 14500 psi 
Impervious to dynamic stresses.
Minimal maintenance expenditures due to a ten times larger than the average market lifetime

Other specifications:

A patented process in which a solid ceramic disk is incorporated into the stainless steel housing makes these sensors resistant to high pressure. 

The Patented technology warrants that all electronic components, including the ferrite core and coil, are on the pressure-free side of the housing. 

This results in an exceptionally long life under the stresses of the pressure cycle.

Two sensors are placed and connected to the control system to track the concrete pump's cylinder limit positions.
