This diaphragm gauge equipped with a sapphire pressure sensor manufactured using MEMS processing technology achieves higher resistance to deposition.
- Higher resistance to deposition minimizes downtime.
- Heat resistance up to 250 °C for use with high-temperature process gases
- Compact body for a smaller footprint
Sapphire capacitance diaphragm gauge model V8 is equipped with a sensor manufactured using MEMS processing technology, achieving higher resistance to deposition.
A single-crystal sapphire pressure-sensing element offers excellent corrosion resistance, ability to withstand high temperatures, and excellent mechanical characteristics. Model V8S can be used in temperatures as high as 250 °C.
Shorter process downtime achieved by higher deposition resistance
With MEMS processing technology, the amount of zero point shift has been reduced to one-tenth that of our conventional products.
Stress-balanced structure
Zero-point shift is reduced by thickening the periphery of the pressure-sensing part to offset the stress applied to the periphery and the central part, thereby making the pressure-sensing part unlikely to deform.
Uneven sensor chip surface
Processing makes the surface uneven, which breaks up deposited film and reduces stress that deposition causes.
Resistant to 250°C for use of high-temperature process gases
The V8S can be used in temperatures as high as 250 °C because its circuit boards and the sensor are separated and special materials are used.
Compact size with smaller footprint
By arranging components more efficiently inside the product, its volume has been reduced by 40 % compared to our conventional products.
