放電・炎センサ（ＵＶトロン）は、金属の光電効果とガス増倍効果を利用した紫外線ＯＮ－ＯＦＦセンサです。感度波長範囲は185 nm～300 nmと、紫外域のみに感度を有しているため、半導体光センサなどのように光学的可視光カットフィルタを使う必要がなく、簡単に使用できます。
当社独自の結晶技術により、波長5 μm帯・8 μm帯・10 μm帯で高感度を実現した検出素子です。高速応答が特長で、変化の速い温度計測、赤外線計測等に用いられます。中でも、P13243シリーズはその感度波長範囲から、炎検知に適しています。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
