Advanced Monitoring for Electrovalve Performance

A commercial electrovalve has been enhanced with a high-resolution strain sensor to detect deformation caused by pressure on the valve surface. This setup provides valuable feedback on valve performance, enabling precise control and monitoring.

Measurement Principle

The strain sensor measures deformation by tracking the mechanical resonance frequency shift on the valve’s external surface.

Testing and Results

Tests were conducted under both static pressure and dynamic conditions by adjusting the PWM control of the solenoid. The results demonstrate the sensor's ability to provide feedback on flow rate, pressure, and temperature, showcasing the potential of MEMS technology in enhancing electrovalve performance.
