Pressure alarms
Devices are used in monitoring and control systems of manufacturing processes in natural gas industry, oil industry, chemical industry and other spheres of industry.
Differential pressure alarm «Садко 44» is meant for commutation of electric circuits after differential pressure reached set value of response.
Differential pressure alarm «Садко 107» is meant for commutation of electric circuits after differential pressure reached set value of response.
Alarms are resistant to operation in following environments: atmospheric air, water, oil, hydrocarbon condensate, natural gas.
Excess pressure transducers are meant for continuous conversion of measured parameter (gas pressure or fluid pressure) into unified output current signal. Alarms are installed in complexes and devices of teleautomatics, in systems of automatic control and adjustment of manufacturing processes on objects of nuclear-power engineering.
Digital signal processing is applied in article at the expense of digital temperature correction.
