Introduction

Principle & Structure

Based on the ceramic capacitor technology, when the pressure on the ceramic capacitor increases, the capacitance value increases correspondingly, and the capacitance value is proportional to the pressure value.

Features

Strong overload capacity, good stability, better than 0.1% of the full scale per year, strong anti-interference ability, extremely high accuracy and repeatability, up to 0.2, 0.5 grades, and good corrosion resistance of the ceramic measurement interface. Flush film versions are available for viscous media. Zero and full scale can be adjusted on site. With LED display.

application

Gas-liquid dual-purpose type, can be used in hydraulic and pneumatic systems. Applicable to the following industries:

Steel industry, machinery and equipment, air compression industry, refrigeration and air conditioning, lifting and transmission systems.
