| Watlow INFOSENSE-PTM Plug and Play Sensors Reduce Process Variation and Decrease Installation Costs |
St. Louis - INFOSENSE-PTM plug and play sensors by Watlow provide a high level of accuracy and convenience through automatically linking the customer's application to Watlow's NIST-traceable calibration lab. The INFOSENSE-P technology incorporates an EEPROM memory chip, preprogrammed with each sensor's part number, manufacturing information and full range temperature calibration. "The memory chip has a direct path into the control or transmitter's microprocessor, automating the process of sensor installation, identification and entering of calibration data," said Mark Lehmann, general manager. INFOSENSE-P sensors utilize IEEE 1451.4 technology, so that when a sensor is wired or connected to IEEE 1451.4 compatible electronics, the controller accesses the information provided and performs a full high-order curve fit to correct for all known errors. Utilizing INFOSENSE-P technology improves initial accuracy of standard thermocouples by three times, and the accuracy of RTD sensors by 10 times at 600 degrees C (1112 degrees F). "Utilization of INFOSENSE-P technology results in a temperature sensor that is now as accurate as Watlow's NIST reference standard. These highly accurate sensors reduce the uncertainty in temperature measurement, thereby decreasing process variation. The three to 10 times reduction in measurement error can significantly improve yield or efficiency," said Lehmann. INFOSENSE-P plug and play temperature sensors can be used in applications throughout a variety of industries, including semiconductor, aerospace, analytical, food processing, furnace, heat treat, life sciences, oil and gas processing, pharmaceutical, power generation and within test stands. About Watlow Since the company's founding in 1922, Watlow has brought its thermal expertise to numerous applications, including semiconductor, plastics processing, foodservice equipment, life sciences, power generation, aerospace and others. Headquartered in St. Louis, Missouri, Watlow is the largest custom designer and manufacturer of industrial heaters, sensors, controllers and software with offices and manufacturing facilities around the world.
