This online conductivity sensor for industrial boilers can measure directly in the blowdown line without sample cooling — saving on installation and operating costs. It enables continuous automatic blowdown control, which minimizes corrosion and scaling to a greater extent than with manual measurement and control. Able to operate well above conditions of conventional sensors, the Boiler Conductivity Sensor (photo) can directly measure samples up to 250 psig (17 bar) at 392°F (200°C). The sensor is used with the manufacturer’s M300 transmitter, which provides display, analog outputs and alarm relays plus on-off and PID control capabilities. It can also be used with the 770MAX transmitter, which accepts four sensor inputs in any combination of parameters including conductivity, pH, dissolved oxygen, flow, ORP, TOC, pressure and tank level, which are often used with boiler-water-treatment systems. — Mettler-Toledo Thornton Inc., Bedford, Mass.
