Pressure Ratio Signalizer SOD Series for Accurate Pressure Monitoring

The units of the SOD family are pressure ratio signallers and are designed to generate a relay signal in the form of pressure and air flow when the set value of pressure ratio is reached.

The DDS is part of the engine compressor control system of the power plant and works in conjunction with the air bypass valves (AVC). The DDS provides opening and closing of the engine compressor control valves according to the set pressure ratio value.

SOD consists of two main parts: measuring part and power amplifier, located in one case.
