Bypass real-time measurement in a tank or boiler. Range from nD 1.3200-1.5600 and 0-95 %Brix
The PRB21S (bypass) is connected to the process using hoses. In this way it is possible, either by pumping or hydrostatic pressure, to guide the sample as a partial flow of the main process (bypass) through the measuring cell and to measure it without interruption. The PRB21S model is used in the chemical, petrochemical, automotive, aircraft manufacturing, food, sugar and beverage industries, as in wastewater control.
Basic functions
- Measurement in refractive index, %Brix or a user-definable scale
- Automatic temperature compensation (%Brix and freely definable for customer-specific products)
- Integrated sensor for temperature monitoring
- Stainless steel measurement chamber and sample prism, made of scratch-proof and chemical-resistant sapphire
- Manual cleaning or via customer process cleaning, CIP capable
- Suitable for process temperatures up to 60 °C
- Simple connection to the process control system or PLC via serial or two-part potential-free current interface (0/4-20 mA)
- Interfaces: RS232; RS232 for display, 2x analog 0(4)-20 mA; relay input, 2x relay output
