Sensor with flange and extention tube The TRA/TCA-F13 is a flange temperature assembly. The main field of application is in tanks or pipelines and a weld neck flange is used to connect them; the particular advantage to this type of thermometer is that they can be coated (e.g. with PTFE), making them resistant to aggressive media. Form acc.

Submersible level probe with ceramic measuring cell The OPTIBAR LC 1010 submersible level probe has been developed for continuous level measurement of liquids in the water and wastewater industry.The high overload resistant ceramic-capacitive measuring diaphragm is safe to install and easy to clean during operation. Together with the robust 316L housing and the highly corrosion resistant TPE cable, this level probe can be used in a variety of ways.

Digital pH sensor SMARTPAT analytical sensors from KROHNE are the first and only sensor line in the market with integrated transmitter technology. The complete circuitry is miniaturised and fits into the sensor head. This technical achievement cuts the price in half compared to all measurement systems without integrated transmitter technology. KROHNE is the only company who offers a real open standard without additional external transmitter and with a direct connection via standardised fieldbus from the sensor to the process control system. The SMARTPAT sensor stores all data and sends these as bidirectional digital signals with 4...20 mA / HART® 7 protocol to the control and asset management systems, handhelds, PC and other peripherals.
