CAS DataLoggers: INTRODUCE MONITORING SOLUTIONS FOR HEATTREATERS

摘要

CAS DataLoggers provided the temperature data logging solution for a factory with multiple lines of (fixed) heat treating ovens. The factory's existing procedures required employees to periodically read temperatures from controller displays and record all these temperatures on a piece of paper. However, this manual method proved to be inaccurate and time-consuming, so the customer wanted to eliminate these recording/transposing errors and extra labor. Since the goal was to increase data precision and quantity and provide high-accuracy reporting to their own customers, data collection needed to be simple and unobtrusive. Management decided that it needed a compact yet rugged solution offering a large number of inputs along with convenient data downloading capability. The factory installed 2 dataTaker DT85 Intelligent Data Loggers to automate their data recording process. The data logger inputs consisted of a combination of new thermo-couple sensors and repeated signals (4-20 mA, 0-5 VDC) from the existing controllers/display units. In case the temperature monitoring scope suddenly needed to expand, the dataTaker inputs could be increased up to 300 channels or 900 single-ended inputs using dataTaker channel expansion modules.
