The Nagano Keiki RB Bimetal Thermometer is a straightforward and reliable temperature measurement instrument. It operates on a simple yet effective principle, utilising two metals with distinct temperature expansion coefficients, wound in a helical shape. As the temperature changes, these metals deflect and transmit the deflection to a pointer, providing an accurate and easily readable temperature reading.
One notable advantage of the RB Bimetal Thermometer is its minimal error due to changes in ambient temperature, which is smaller compared to the filled-type thermometers. Furthermore, it boasts a safe and eco-friendly design as it does not contain any filled liquids, ensuring there is no risk of pollution. Its uncomplicated design also translates into a reasonable price point, making it a cost-effective choice for temperature measurement needs. When selecting a thermometer from the RB series, it’s advisable to choose one suitable for the specific temperature range of interest, typically within 75% of its total range. Additionally, it’s essential to ensure that the wetted parts’ material is compatible with the gas or liquid to be measured, ensuring accurate and safe temperature monitoring across various applications.
