The TH-140-0020 is a versatile panel meter accessory that has a wide range of applications and working principles. It is designed to provide accurate readings for a variety of control systems and devices, such as temperature, pressure, and other popular panel meters. In addition, it is built with the flexibility and versatility to be easily configured to fit the needs of many industrial environments.The TH-140-0020 is designed to easily mount on a standard panel meter and read the current level of the measured parameter that is being monitored. It also has the ability to sense the temperature of the panel itself, which is used to provide a more accurate reading. This feature, combined with the adjustable response to input signals from the sensor, helps to improve the accuracy of the readings on the panel meter. The working principles behind the TH-140-0020 are two-fold. First, it uses a thermistor based temperature sensor to detect the current temperature within the enclosure. Then, it converts this data into an analog electrical signal that is detected by the device and used to adjust the display accordingly. In addition to converting and displaying the measured temperature, the panel meter also has the ability to detect changes in the environment, such as humidity, air pressure, and others.In terms of applications, the TH-140-0020 is perfect for applications where accuracy and safety are of utmost importance. This includes industrial environments, automotive diagnostics, aircrafts, and more. It is also ideal for applications where precise readings are required in order to achieve consistent performance over time, such as in medical imaging systems, process control systems, and monitoring systems.In summary, the TH-140-0020 is a versatile panel meter accessory that is designed to provide accurate, reliable readings in a variety of applications. It features an adjustable response with its thermistor based temperature sensor, as well as the ability to detect changes in the environment. This makes it well-suited for a variety of different industrial, automotive, and medical applications.
