• Vacuum Equipment

Vacuum technology is required in many industries, and various production equipment is used. The environment within these production facilities varies greatly, ranging from atmospheric pressure to 10^-5 Pa, and most production equipment consists of a series of continuous processes with different processing environments. Therefore, it is crucial to dynamically measure and understand the pressure distribution and gas flow near each process and product, as these factors influence product quality and productivity. However, due to constraints such as the size of vacuum gauges, measurements cannot be taken at the desired points and can only be installed near the outer walls of the equipment, resulting in "indirect" measurements. Consequently, the environmental conditions of the equipment are derived from simulations and other results. With micro-hakumaku pressure sensors, which are ultra-compact and robust, it becomes possible to install them within the equipment environment, allowing measurements in areas that were previously inaccessible, thus visualizing previously unseen conditions. This leads to improvements and monitoring of the optimal equipment environment, achieving low carbon emissions (reduction of environmental impact) through enhanced product quality and increased yield.

The microcoil vacuum gauge is a vacuum gauge that utilizes the thermal conductivity of gases. Generally, the Pirani vacuum gauge is well-known among thermal conductivity vacuum gauges, and it is widely used because it is relatively inexpensive and easy to handle compared to other types of vacuum gauges. However, its measurement range is narrow, and it can be affected by the measurement environment, as well as being prone to disconnection due to vibrations and shocks, making it not very durable in harsh conditions. The microcoil vacuum gauge also uses the thermal conductivity method like the Pirani vacuum gauge, but it can measure over a wider range than conventional Pirani gauges and has enhanced features for measurement stability, environmental durability of the sensor part, and ease of handling.
