New additions to highly successful series of level transmitters

Krohne has recently introduced several new additions to the Optiflex series of guided radar (TDR) level transmitters. Each device is designed for specific areas of application in the chemical, oil and gas, power, metals, minerals and mining, pharmaceutical or food and beverage industries. 

Optiflex 7200 aims at the chemical and oil/gas industries for level and interface measurement of liquids in process and storage applications with ±2 mm/ ±0.08¨ accuracy. It offers an extensive choice of probes for measuring distances up 60 m/ 197 ft and dielectric constants down to 1.3 (TBF 1.1), and can be used with aggressive media in process conditions up to +250°C/ +482°F and 100 barg/ 1450 psig. 

Optiflex 8200 has similar features and offers a double ceramic process seal system for liquids up to +315°C/ +599°F and 320 barg/ 4641 psig. Both devices offer Dynamic Gas-phase Compensation (DGC) (in preparation) with the coaxial probes, ensuring accurate measurement without increased blocking distance in applications where the composition of the gas above the liquid can change suddenly, e.g. in steam boilers. 

All of Krohne’s new TDR transmitters feature 2-wire 4…20 mA HART 7 communication with an optional second output (current or relay) and a real-time clock for event logging. They have been developed SIL 2/3-compliant according to IEC 61508 for safety-related systems and come with various Ex approvals. Common features also include a quick coupling system as well as compact and remote converter versions (up to 100 m/ 328 ft) made of aluminum or stainless steel. All devices are rated IP66, IP68 and NEMA 4X/6P.
