Description
In the discipline of measurement, the most important consideration is the quality of the measurement of the basic quantity. ASL's bridge technology represents the peak performance of resistance temperature measurement technology. ASL leverages the inherent advantages of AC bridge technology to ensure the highest accuracy and highest measurement repeatability under real-world operating conditions.
CTR9000 reference standard resistance temperature measuring bridge designed for the highest precision resistance temperature measurement.
Using 25/30 2) Hz or 75/90 2) Hz operating frequency for fast, continuous measurements and minimizing the effects of thermoelectric potential and power frequency noise.
The actual measurement process needs to take into account the cable, connector and non-ideal working environment. The CTR9000 is able to ensure specification requirements under a wide range of practical operating conditions. AC bridge technology is always a better way to measure than DC technology with slower current feedback. These advantages are inherent in the electrical measurement foundation, not just the product.
