Rolls-Royce Bibloc nuclear pressure transmitters are designed for measuring differential, relative or absolute pressures inside the containment of nuclear power plants under normal or accidental conditions.
The transmitters, designed specifically for nuclear power plants, are composed of two parts, sensor and converter. The sensors are different, according to the measurement range, but the electrical converter is common to each type of sensor.
Rolls-Royce Bibloc nuclear pressure transmitters deliver an electrical signal varying from 4 to 20 mA proportional to the measured pressure.
Rolls-Royce Nuclear pressure transmitters are available in K1 nuclear safety class (seismic and LOCA resistant) and K2 nuclear safety class (seismic-resistant and «normal life» irradiation).
Rolls-Royce pressure transmitters are manufactured in accordance with quality class Q1.
