Detailed Description
I.Overview of ES series sensor cores
The ES series strain - type cores are small in size, light in weight, high in accuracy, and easy to install and use. They have strong resistance to vibration and impact, and can withstand an overload of 100% - 300% of the nominal range (varying depending on the core type). They have high sensitivity, reaching up to 1 micro - strain. Some cores have good dynamic response and can respond to dynamic strains as high as 0 - 500,000 Hz. Many products have obtained patents. They are widely used in the measurement and control of the pressure of media such as water, oil, gas, gel, mortar, glue, food chemicals, powders, and non - setting slurries and adhesives (varying depending on the core type).
II.Operation environment of ES series sensor cores
1.Ambient temperature: - 30~70℃;
2. Relative ambient humidity: ≤90% (at 25℃);
3.Atmospheric pressure: 80-106KPa
4.Without strong vibration and impact;
5.Measurement of the pressure of various liquids, gases, powders, slurries, etc. that are compatible with the contact medium materials
