B&C Electronics PH 7615
The controller uses pH sensors and temperature sensors Pt100
Its robustness and ease of use make it suitable for measurements and adjustment of pH at low cost.
General informations
his series of controllers has been designed to carry out the
measurement and the regulation of:
• pH
• O.R.P
• E. Conductivity
• Free Chlorine
• Temperature
in industrial processes, with continuous readings on digital
indicators.
These instruments give both a valid, low cost measurement and
regulation system for small industrial and ecological plants, and
they can be used as 0/20 mA or 4/20 mA visualized
transmitters for field applications.
Connections are made by means of two extractable terminal
blocks on the rear side of the instrument, which allow easy cables
connection and easy maintenance of the instrument.
The panel mounting instrument’s enclosure is designed according
to the DIN 43700 standards and it consists of a plastic case with
metallic front panel coated with a polycarbonate membrane, to
ensure the maximum anticorrosion characteristics.
A transparent splashproof front door can be added to the housing,
in order to protect the unit from excessive moisture or corrosive
fumes.
The package is supplied complete with fixing clamps for panel
mounting.
