The SWT-99X Multi-channel Temperature indicator is designed to measure and display up to 8 channels of Thermcouple, RTD or mV inputs. By locating the precision amplifiers on the rotor, superior data accuracy is achieved because the amplifier is located closer to the sensor. I wish to build a multi-channel (say 3) thermocouple meter. The card has been specially developed to provide high performance at low cost in multi-channel applications. Keep up to date conveniently by newsletter. Temperature Amplifier, 2- or 4-Channeles. Since the transfer function of a thermocouple is in μV/ºC, a proper signal conditioning circuit is necessary to amplify the thermocouple’s output to a proper voltage value for further processing. Q2. Shop our selection of in-line amplifiers, USB field-calibratable signal conditioners, low level amplifiers, and more today. For applications that require more than three channels, the amplifiers may be stacked or arrayed around an adapter plate. It was developed for industrial applications and opti- mized for use with the ComoNeo Type 5887A, CoMo Injection Type 2869A…/B... and Kistler sensors. Tianjin University of Technology and Education . The scanner's display will auto cycle through all input channels at a user determined rate of 0.5~10 seconds per channel. This reduces errors due to long lead wires, connector resistance variations, electro-magnetic interference, and temperature gradients across slip ring contacts. These Modular Spinning Thermocouple Amplifiers provide amplification for two or three thermocouple channels. I found a thread on this forum describing a circuit I liked.
