Many people know “Ondotori” as a data logger for recording “temperature” from its name which includes the word “ondo” or temperature in Japanese. In Japan, our data loggers are often referred to as “Ondotori”. “Ondo” here is Japanese for “temperature” and “tori” expresses a “thing that takes”, so a “thing that takes temperature”. But the name “Ondotori” when using different Japanese characters means to take a leadership role. The name reflects our wish to take a leadership role in the world of data loggers. Although not as well known as our temperature loggers, there are several models in the Ondotori-Series that can measure and record data other than temperature. Using a wide variety of sensors, these models measure and record voltage, current (4-20mA), and pulse signals. They can record these values as noise (dB), wind speed (m/s), rainfall (mm), etc…. Furthermore the measurements can be recorded and saved to the cloud for easy monitoring of these values; making them useful across various industries. In this article, we will introduce how T&D voltage, current (4-20mA), and pulse loggers are used to measure noise and vibration at construction sites.
