pH/ORP-meter industrial for nuclear power stations
PH-meter 4121.NP is a one-channel pH-meter consisting of a sensor with primary transducer (PT) and a
measuring instrument (MI).
The pH-meter for NPP is designed for use in severe environmental conditions, namely on seismic resistance,
climatic conditions, radiation resistance, difficult situation for electromagnetic compatibility (EMC).
PT electronic unit enclosure is made of stainless steel,
which enables to make its processing with decontamination fluids.
pH-meters for NPP are designed in two versions:
monoblock – PT electronic unit is mounted on the holder;
separate – for use in the radiation zone
PT electronic unit is mounted separately from the holder up
to 20 meters in a protected room. PH-electrode is connected to the PT with a special connector with a cable.
The pH meter converts the measured parameters to a unified analog DC output signal,
provides data exchange with a computer via a digital interface RS-485 (Modbus protocol), and signals the output of measured parameters beyond the limits of specified values.
Areas of application: nuclear power, as well as other
industries where super reliable measurement of the activity of hydrogen ions (pH) in harsh operating conditions is required.
PH-meters for NPP can be used complete with a hydraulic panel HP-4122 to provide a control of highly demineralized water.
