The SPG5/6/7 sapphire diaphragm gauges feature a single-crystal sapphire pressure sensing element, which offers excellent corrosion resistance, the ability to withstand high temperatures, and strong mechanical properties. Additionally, these gauges detect static capacitance, ensuring superior measurement repeatability, even in high-temperature environments.

These self-heating diaphragm vacuum gauges use advanced signal processing technology, which optimizes temperature characteristics and linearity with minimal measurement error. The sapphire sensor, created using micromachining technology, contributes to their compact size and light weight.

Improving Quality

Vacuum gauges are often used in extremely high-stress environments, where zero point deviation can occur due to various factors. Such deviation affects the controlled variable, which, in turn, impacts the final product quality. However, the SPG sapphire diaphragm vacuum gauges prevent zero point shifts with an effective mechanism.

Improving Productivity

These gauges reduce plant downtime and include features that minimize wasted time.

Improving Processes

They enable the visualization of various types of information, which previously could only be determined by changes in the pressure signal. This enhancement contributes to improving production processes.
