TSS sensors & transmitter.

Krohne has added two new total suspended solids (TSS) sensors and a transmitter to its analytical portfolio.

OPTISENS TSS 3000 is a total suspended solids sensor for wastewater applications in various industries with 1 1/4 NPT thread to fit into a retractable or immersion assembly. OPTISENS TSS 7000 is a total suspended solids sensor for hygienic applications with Tri-Clamp or VARIVENT* process connection, e.g. in milk separation, fruit processing and other food and beverage applications. It can also be used for hygienic concentration measurement in other process industries, e.g. for monitoring steam or cooling water circuits.

OPTISENS TSS 3000 and 7000 both are glass free optical sensors with multiple path lengths for various concentration ranges. They use alternating light 4-beam technology for a higher reliability of the measurement compared to classic 2-beam technologies. 2 NIR LEDs (880 nm) light sources and 2 detectors compensate for most errors caused by dirt, aging or light source variations. By measuring directly through a PP layer, measurement errors and sealing problems typically caused by glass windows cannot occur. Both can be operated with the MAC 300 analytical transmitter.

MAC 300 is a menu driven analytical transmitter for OPTISENS TSS, pH/ORP and COND sensors. It can be operated with up to three different analytical sensors, processing their signals to the control system via up to six analogue 0/4...20 mA outputs, relay outputs or optional Modbus. It features a backlit LCD display, robust housing (IP66/67, NEMA 4/4X) for wall-mount or panel-mount installation, optional live trending and data logging, and an SD card slot to save parameter sets or upload new firmware.
