Measuring and computing complex SANPO for monitoring, diagnostics and emergency shut-down of dynamic equipment

SANPO-19-09-16Measuring and computing complex SANPO for monitoring, diagnostics and emergency shut-down of dynamic equipment is a unique design of “Komdiagnostika” which meets the requirements of API670 standard (American Petroleum Institute, Equipment protection systems).

Complexes SANPO are designed for an online application in vibration protection and vibration monitoring systems of industrial equipment as well as for registration of failures, control of alarm, interaction with emergency protection system of the upper level.

Application area: for measuring and transducing output signals from the primary vibration transducers (vibration speed, vibration acceleration, vibration displacement), shaft displacement, rotation frequency, temperature, including resistive temperature transducers and thermoelectric transducers, and reproduction of converted signals as a unified power and direct current voltage signals.

The complexes are multifunctional microprocessor devices, their operation is set by a software installed on the external PC with measuring channels remote setting and configuration functions.

The complexes consist of condition modules, power supply modules and access modules, modules of parametrical input-output as well as of temperature and vibration measuring modules.

The complexes have block-modular structure “Euromechanics” with modular data acquisition system rack as its basic element. Depending on the needed number of modules there are two modifications of racks -  16-slot (number of measuring modules is from 1 to 13) and 8-slot (number of measuring modules is from 1 to 5).

MAIN ADVANTAGES:
- redundancy of power supply units and modules;
- hot swap of power supply units and modules;
- modular design;
- easy installation;
- conformance to API 670 standard;
- high working capacity and faults tolerance;
- flexibility and high functionality;
- high reliability;
- 3 years of calibration interval;
- no need to calibrate a channel after a swap of one or several elements of the measuring tract;
- full cycle of domestic manufacture and assembly.
