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.

The OPTIBAR LC 1010 is a submersible level probe for water and wastewater, environmental engineering and OEM applications. It is particularly suitable for continuous hydrostatic level measurement in water wells, rainwater retention and overflow basins or tanks. The level transmitter features a robust stainless steel housing and a high overload-resistant ceramic diaphragm for long-term operation. The diaphragm is flush mounted for safe and easy cleaning on site. The level probe comes with pre-configured measuring ranges from 100 mbar / 1.5 psi to up to 10 bar / 150 psi. Customer-specific ranges are available on request. Its corrosion-resistant TPE cable is approved for use in potable water applications. The OPTIBAR LC 1010 features a 4…20 mA output and optional HART®7 for convenient configuration. The level probe can also be provided with an integrated Pt100 temperature sensor.

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.

Free chlorine/chlorine dioxide/ozone measuring system for water applications The OPTISYS CL 1100 measuring system consists of the membrane free OPTISENS CL 1100 sensor. The sensor is characterised by standardised design, easy handling and a long life cycle. Together with the MAC 100 converter, flow-through holders, valves, temperature sensor and an optional pH sensor OPTISENS PH 8500, this is a tested and ready to use measuring system which is very reliable and easy to maintain. The system is suitable for a wide range of water analysis measurement tasks. — Complete measuring system – ready to use and easy maintenance — High quality and precise gold electrodes for usage in water analysis — Membrane-free sensor for a wide application range

The OPTISENS IND 1000 is a fully enclosed inductive conductivity sensor for use in heavily contaminated, aggressive media such as industrial or municipal wastewater. It features an extremely rugged design using corrosion-resistant and dirt-repellent materials like PP or PVDF. The measuring cell with two inner ring-shaped measuring coils is completely enclosed and is thus not in contact with the media. The compact sensor design is particularly suited to installation in pipes with small diameters. The OPTISENS IND 1000 easily connects with the MAC 100 or any other analytical transmitter.

The OPTISENS PH 8100 is an all-purpose pH sensor for demanding applications in chemical and petrochemical industries as well as for process water, wastewater or other aggressive media. Its glass electrode is particularly suitable for use in highly alkaline solutions or applications with low conductive media (>2 μS/cm) and temperatures up to +130°C/ +266°F. The sensor is equipped with two open diaphragms to prevent clogging and to ensure reliable measurements. It is also available with integrated Pt100 for temperature compensation. Various mounting assemblies allow for easy installation and reliable handling of the sensor. The pH sensor can even be installed upside down. It operates with the MAC 100 or any suitable analytical transmitter.
