Radiation-resistant pressure transducers and signaling devices

Radiation-resistant pressure transducers PDA-RS, PID-RAS, PID-RAS are designed to measure the absolute, excess and differential pressure of controlled media with the formation of unified output signals.

Scope of application — systems for automatic control of parameters of nuclear power plants.

Upper limits of the measured absolute pressure

0,1; 1; 1,6; 2,5; 4; 6; 10; 16; 25; 40 MPa

Upper limits of the measured overpressure

0,1; 1; 1,6; 2,5; 4; 6; 10; 16; 25; 40 MPa

Upper limits of the measured differential pressure

- 6,3; 10; 16; 25; 40; 63 kPa
- - 0,1; 0,16; 0,25; 0,4; 0,63; 1,0; 1,6; 2,5 MPa at the maximum permissible operating overpressure of up to 25 MPa

The delivery set of the pressure converter (alarm) of the group version includes:

primary measuring converter;
secondary converter group;
a permanent storage device module.

The housing of the secondary group converters can be supplied separately or together with the secondary group converters according to the order.

The housing of the secondary group converters is made in the form of a block in two versions:

to accommodate four secondary group converters;
to accommodate eight secondary group converters.

The design of the housing of the secondary group converter provides connection to each secondary group converter separately:

power supply circuits;
communication lines;
primary measuring converter;
a permanent storage device module.
