Patent number: 8996327Abstract: An I/O circuit for measuring temperatures uses multiple cold-junction compensation sensors permanently affixed near the terminals of the terminal block in order to compensate significant temperature variation across the terminals of the I/O module (up to 3° C.) that can substantially affect the accuracy of thermocouple measurements. The use of these multiple sensors is enabled by a compensation system that corrects for the distance between the built-in sensors and the terminals, a multiplexer that accommodates the additional signal burden produced by the sensors, and a compensation system that allows low-cost sensors to be used and calibrated to as little as a single high accuracy sensor. In one embodiment, a third temperature sensor with relatively higher accuracy is used to compensate for lower accuracy of permanently affixed sensors.Type: GrantFiled: January 11, 2012Date of Patent: March 31, 2015Assignee: Rockwell Automation Asia Pacific Business Ctr. Pte. Ltd.Inventors: Liang Ge, Xiaofan Chen

Patent number: 8992081Abstract: A high temperature measurement probe comprises an elongate probe body having a measuring head which in use is located in a hot fluid flow. The probe further comprises a thermocouple extending along the interior of the probe body to terminate at a temperature-sensing thermocouple junction inside the measuring head. The probe body has internal passages for circulation of a coolant fluid therein. The measuring head contains a channel, one end of the channel forming an inlet for receiving hot fluid from the hot fluid flow and another end of the channel forming an outlet for discharging the hot fluid received at the inlet. Between the inlet and the outlet a section of the channel extends along the length direction of the probe body. The thermocouple runs along the section of the channel with the thermocouple junction proximate the upstream end of the section.Type: GrantFiled: June 16, 2011Date of Patent: March 31, 2015Assignee: Rolls-Royce PLCInventors: Peter Ireland, Andrew Wilson, Steven Thorpe, Damian Martin

Publication number: 20150036721Abstract: A temperature measurement module having position compensation provided for connection to at least one thermocouple includes a temperature-dependent resistor, via which a first temperature of a reference point of the thermocouple can be detected as a resistance voltage. The temperature measurement module includes an evaluation circuit which allows a first temperature value of a measurement point to be determined via the resistance voltage and a thermoelectric voltage of the thermocouple. The temperature measurement module includes a compensation mechanism which modifies the first temperature value depending on the installation position of the temperature measurement module so that thermal influences of the evaluation circuit, which have a thermal effect on at least one of the reference point or the measurement point depending on position, are compensated at least in part.Type: ApplicationFiled: February 21, 2013Publication date: February 5, 2015Inventors: Hubertus Lohre, Norbert Joestingmeier
