The OPTITEMP TRA-C61 is a compact resistance sensor (RTD) with optional integrated transmitter for hygienic use in limited space. The temperature sensor is particularly designed for food & beverage applications. This includes the temperature measurement of beverages, dairy products or pasty food. The sensor is therefore made of stainless steel (1.4404 / 316L) with an industry-specific surface finish of the thermowell of Ra ≤0.8 μm. It complies with FDA and EC1935/2004 regulations. Its G¹⁄₂ thread for hygienic adapters leaves freedom of choice for the process connections. The compact RTD sensor is available with VARIVENT^®, dairy screw (DIN 11851), SMS 1145 as well as different weld-in sleeves.

The OPTITEMP TRA-C65 is a compact resistance sensor (RTD) with optional integrated temperature transmitter for hygienic use in limited space. The temperature sensor with firmly welded clamp connection is particularly designed for applications in the food & beverage industry. This includes the temperature measurement of beverages, dairy products or pasty food. The sensor is therefore made of stainless steel (1.4404 / 316L) with an industry-specific surface finish of the thermowell of Ra ≤0.8 μm. It complies with FDA and EC1935/2004 regulations.

The KROHNE Venturi based wet gas solutions, WGS 1000 / 2000 / 3000, are designed to measure the flow of unprocessed gas directly from the well. Intermediate parameters at the point of measurement are calculated from known reservoir and well compositions and used to generate fraction and density tables for the operational range of the well or reservoir.

FOCUS-1 is the first intelligent process node specifically developed for the process industry 4.0. This multifunctional smart flow control instrument – developed by FOCUS-ON, a SAMSON and KROHNE company – combines sensors, actuator and control functionality in one device. By measuring flow, pressure and temperature simultaneously and regulating its valve function independently, all specified set points can be accurately and reliably achieved. In this way, the device acts as an autonomous actuator for decentralised control tasks. There is no need to establish complex control loops or connect with a DCS. This makes FOCUS-1 the ideal smart control unit for the autonomous factory. It is equally suitable for process industry 4.0 applications in greenfield projects as well as process automation in existing brownfield applications. The process node can also be used as a drop-in replacement of conventional valves to increase diagnostic capability.

The OPTIBAR PSM 2010 is an electronic pressure switch for applications in the food and beverage industry as well as the pharmaceutical industry. Its hygienic construction comes with a fully welded front-flush diaphragm to meet the most stringent industrial requirements in terms of crevice-free installation. The pressure switch provides long-term stable absolute or gauge pressure measurement of liquids and gases as well as hydrostatic level measurement. Due to its advanced digital compensation, the OPTIBAR PSM 2010 offers excellent temperature stability even during SIP/CIP cleaning cycles.

The OPTIWAVE 5400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in basic process applications. It is particularly designed for continuous, non-contact level measurement in the chemical, petrochemical, power as well as oil and gas industry. It can be equipped with a PP Drop antenna for condensing atmospheres and corrosive media but features also Metallic Horn antennas. Due to its high dynamic range, the 24 GHz radar can measure distances up to 100 m / 328 ft.

The OPTIWAVE 6500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding applications with powders in very dusty atmospheres. With its small beam angle, this radar is particularly suited for continuous, non-contact level measurement in high and narrow silos, hoppers or buffer storage containers up to 100 m / 328 ft. Due to specific algorithms and the high signal dynamics of the FMCW radar, the level transmitter is ideal for low-reflective media, dust, uneven surfaces or silos with internal obstructions. As it features flush-mounted PEEK and PTFE Lens antennas, there is no intrusion into the tank.

The OPTIWAVE 7400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in harsh environments like tanks with agitators containing corrosive media. It is particularly designed for continuous, non-contact level measurement under extreme conditions prevalent in the chemical, petrochemical, power, metal or oil and gas industry. The device features Metallic Horn antennas as well as PTFE and PEEK Drop antennas for measuring distances up to 100 m / 328 ft. The Drop antennas are perfectly suited for aggressive liquids in tanks. In applications with toxic and dangerous products, this radar device can be equipped with a METAGLAS^® second sealing barrier.

The OPTIWAVE 7500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding liquid applications involving narrow tanks with long nozzles and internal obstructions like agitators or heating coils. Its very small beam angle and negligible dead zone make this FMCW radar the optimal choice for continuous, non-contact level measurement in both extremely small and very high tanks (up to 100 m / 328 ft). The level transmitter is even able to measure through tank roofs made of non-conductive materials. Its PEEK and PTFE Lens antennas are insensitive to deposits and well suited for corrosive environments. As the antennas are flush-mounted, there is no intrusion into the tank.
