Chemistry modules

ATI gas-phase chemistry modules from Analytical Technology Inc. are online monitoring systems that use air-stripping methodology designed for sample streams that are highly contaminated with solids or biological activity. Modules for dissolved oxidants use iodometric chemistry to prepare the sample stream for measurement. Modules for non-oxidizing chemicals use pH adjustment of the sample before measurement.

After chemical addition, the integral air pump provides a continuous stream of ambient air to the reactor assembly to release the analyte from the water phase and into the gas phase. A special gas-phase sensor detects the chemical concentration in the air stream. By using air-stripping technology, the sensor is removed from the liquid phase, preventing fouling. The low-maintenance technology lowers operating costs. The modules are available with total residual chlorine, residual sulfite, dissolved sulfide, and potassium permanganate monitors. 800/959-0299; www.analyticaltechnology.com

Electromagnetic systems

Dynamatic electromagnetic variable-speed pump and centrifugal blower drive systems from DSI Dynamatic employ eddy current technology, consisting of a constant-speed AC induction motor and magnetic clutch governed by a small digital controller. The amount of power available is determined by the motor size (1/4 to 2,000 hp). A rotating drum is connected to the motor shaft, and an electromagnetic coupling is used to vary the speed of output. The only wear parts are bearings, as the motor and drive are separated by an air gap.

A clutch coil, tachometer, and output bearing complete the
internal components in standard drives. A digital clutch controller that typically uses less than 1 percent of the total system power governs the voltage sent to the clutch coil. The AC motor runs at optimum rated speed. By regulating voltage to the clutch coil, a magnetic flux field is created, and distortion of the field creates torque. The greater the power to the coil, the greater the strength of the field and output torque. A tachometer provides output feedback to the digital controller, making this a closed-loop system. 800/548-2169; www.dynamatic.com

Shaft slowdown prevention

Electro-Sensors provides a system consisting of the LRB1000 shaft speed switch, a 906 shaft speed sensor, and a split-collar pulser wrap with magnetic targets that can provide an early warning of shaft slowdown or stoppage, preventing downtime and repairs. The LRB1000 receives a frequency from the 906 as it reads the magnets on the pulser wrap that is clamped around the flocculator shaft. The LRB1000 compares this frequency to the preset programmable setpoint and provides an early warning if the shaft slows down below the setpoint due to motor failure, shaft breakage, or some other event. 952/930-0100; www.electro-sensors.com
