Overview
The ST-540SS-HR is designed for high pressure boiler water tracing applications. The ST-540 Series are inline fluorometers are designed to conduct research and development of NDSA traced boiler or process water treatment programs. We offer direct measurement of NDSA utilizing LED light sources. For use in boiler water and boiler feed water measurement applications. The ST-540SS-HR offers Pyxis algorithms to determine the concentrations of NDSA at a range of 0-2,000ppb. It also while simultaneously measuring light loss through the optical channel to determine sensor cleanliness. The ST-540 Series offers a combination of 4-20mA as well as RS-485 Modbus output signals. Bluetooth Enabled for wireless cleanliness diagnostics. And also calibration when used with MA-WB or PowerPACK Series. The ST-540Series is provided in both UPVC and304 stainless steel for use in a cooling and process water or cooled and pressurized sample (<120 ºF) of boiler water or boiler feed-water. Each sensor is provided with a 1.5m bulk head cable with 7-Pin quick adapter and 1.5m cable with 7-Pin quick adapter. This enables rapid wiring to any microprocessor controller, PLC or DCS system. The MA-WB Bluetooth adapter enables wireless access for use with the uPyxis Mobile or Desktop APPs for diagnosis and calibration.
