Sapphire Capacitance Diaphragm Gauges / Sapphire Capacitance Diaphragm Gauge Models V8C/V8S

Model V8 Sapphire Capacitance Diaphragm Gauge

The Azbil Sapphire Capacitance Diaphragm Gauge Model V8 is equipped with a sensor manufactured using MEMS processing technology, achieving higher resistance to deposition and shorter process downtime. With MEMS processing technology, the zero point shift has been reduced to one-tenth that of our conventional products. The Model V8 has a high-speed response time as fast as 1 ms.

A crystal sapphire pressure-sensing element offers excellent corrosion resistance, the ability to withstand high temperatures, and excellent mechanical characteristics. The Model V8S can be used at temperatures as high as 250 °C (482 °F) because its circuit boards and sensor are separated and special materials are used.

Features

Stress-balanced structure

The zero point shift is reduced by thickening the periphery of the pressure-sensing part to offset the stress applied to the rim and the central region, making the pressure-sensing part unlikely to deform.

Uneven sensor chip surface

MEMS technology makes the surface uneven, breaking up film deposited on the sensor diaphragm and reducing the stress that deposition causes, dramatically reducing the zero point shift.

Compact design

The Models V8C/V8S offer a smaller footprint. By arranging components more efficiently inside the product, volume has been reduced by 40% compared to our conventional products.
