Analytical sensors with integrated transmitter

10-05-2016
Introduced in 2013, SMARTPAT is the first family of analytical sensors that no longer require transmitters: KROHNE miniaturised the transmitter and fitted it into the sensor head. SMARTPAT sensors significantly reduce the risk of failure from sensor to process control system and ease the handling of analytical sensors in a revolutionary way.
Any SMARTPAT sensor can be connected directly to the process control system, featuring direct communication via 4…20 mA/ HART® 7 protocol, the open standard in fieldbus systems. Sensor configuration is possible via PACTware (FDT/DTM) or a handheld device with HART® DD. SMARTPAT sensors function in a 2-wire loop powered system. They can be used both in point-to-point operation and for multi-drop installations. Up to 32 sensors can be connected in a loop of more than 1000 m / 3280 ft in length.
For offline sensor calibration the sensor can be connected directly to a PC running PACTware (FDT/DTM), using just one cable for bi-directional HART® 7 communication and power supply. Due to the controlled, clean conditions in the laboratory, a much more exact calibration can be performed. This enables more precise measuring results and higher product quality.
Each SMARTPAT sensor is specifically designed for its area of application: approvals and certificates range from installation in explosive (zone 0) to hygienic areas. A large portfolio of accessories, including loop powered displays, USB interface cable and mounting assemblies, ensures that SMARTPAT fits into your application.

Highlights:

  • No external transmitter needed
  • Direct communication via 4…20 mA/HART® 7
  • VarioPin 2.0 plug connection
  • 2-wire sensors for unrestricted use in hazardous areas with zone 0 approval (e.g. IECEx)
  • Configuration and offline calibration via PACTware with dedicated DTMs
  • Consistent software and operating concept for handheld and PC
  • SMARTBASE database for sensor data management and statistics
  • Easy installation and retrofitting on site: sensors fit 98 % of all existing mounting assemblies
