Yokogawa's new pH and conductivity analysers
cut installation and set-up time.
Designed for OEMs and set builders, Yokogawa's new
EXAxt 150 Series of pH and conductivity analysers dramatically
cut installation and set-up time using an innovative integral
mounting system and simple termination.
The compact 96 × 96 mm configuration allows exceptionally 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 new range 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 new EXAxt 150 Series is based on the industry-leading analyser
technology used in Yokogawa's established field-mountable EXA Series of
instruments, with the addition of enhanced diagnostic features and a unique
touch-screen interface with a backlit VGA graphical liquid-crystal display.
The touch-screen interface provides simple, intuitive configuration and
display facilities, including the reading of primary and secondary values,
real-time trend graphing of process variables, diagnostics, event logbooks,
and configuration data.
The pH/ORP and conductivity analysers are fitted with two mA outputs as
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
included as standard.
Other features of the new devices include comprehensive, easy-to-use
calibration routines, temperature-compensation functions, and global buffer
tables.
The combination of high performance, ease of installation and compactness
makes the new analysers ideally suited to the requirements of equipment
manufacturers and machine builders serving application sectors such as water
supply, waste treatment, food and drink and semiconductor processing.
