Analysers cut installation and set-up time
Yokogawa's EXAxt 150 Series of pH and conductivity analysers have been designed to cut installation and set-up time using an innovative integral mounting system and simple termination.
The compact 96 x 96mm configuration allows high panel density, with very little room needed behind the panel. Waterproof sealing is to IP65 and a flip-top transparent cover is fitted to keep the display clean. Straightforward mounting is ensured by a unique built-in fixing system, which, together with removable terminal connections, will halve installation time.
The first two instruments in the series are the pH150, which will simultaneously measure and control both pH and ORP (redox) in process and waste water, and the SC150, for measuring and controlling specific conductivity. The series features enhanced diagnostics and a touch-screen interface with a backlit VGA graphical liquid-crystal display.
Two mA outputs are standard for transmission or control of the measurement parameters. The transmitted or control parameters for the pH/ORP unit may be pH, ORP or temperature. The conductivity unit can transmit or control conductivity, resistivity, percentage concentration, or temperature.
Two relay contacts can be used for alarms or as control signals with frequency or pulse-width-modulating switching, and all control settings are fully configurable. Hart communication and PID control functions are also included as standard.
