Overview
Description
Using the evaluation board (RSSK RX23E-A) equipped with RX23E-A and peripheral circuits for sensor measurement, and software that can be downloaded from the web, you can start analog characteristic evaluation immediately after purchasing the kit. By using this kit, it is possible to shorten the development period and bring it to market quickly.
The kit consists of an evaluation board with the RX23E-A and peripheral circuits for sensor measurement, a K-type thermocouple, and is provided with the GUI and sample programs. These ready-to-use tools enable users to start evaluation of the A/D converter without hardware modification or software development.
The kit can be utilized to evaluate the measurements of thermocouples, RTD, and strain gauges, which are typical sensors in industrial equipment. Our evaluation of K-type thermocouples using the RSSK shows that the measured temperature error is within ±0.6°C under environments between -40°C and 85°C and the effective resolution is 19.4 bit, which means temperature deviation is equivalent to 0.0015°C at rms value. The measured temperature error, which is within the sensor error, validates the evaluation board as a reference design.
