Analytical sensors with integrated transmitter technology
Krohne
Smartpat is a family of two-wire loop-powered analytical sensors (photo) with integrated transmitter technology for direct connection of the sensors to process-control systems. All sensors are digital and can be calibrated or recalibrated offline in a laboratory under controlled conditions. For offline calibration, the sensor can be connected directly to a PC running the same FDT/DTM frame applications (for example, PACTware) as applied in common asset-management systems, using a USB interface cable for bi-directional HART 7 communication and power supply. According to the manufacturer, this is a significant improvement over other analog analytical sensors that must be calibrated onsite together with the transmitter, even if installed at remote or difficult-to-reach measuring points, which can also cause sensor calibration to trigger false values in the process-control system.
