Бар
1 бар = 0,1 Мпа 1 мм рт.ст. = 13.6 мм вод.ст.
1 бар = 10197.16 кгс/м2 1 мм вод.ст. = 0.0001кгс/см2
1 бар = 10 Н/см2 1 мм вод.ст. = 1 кгс/м2
1 атм = 101.325 ∙ 103 Па
Па
1 Па = 1000МПа
1 МПа = 7500 мм. рт. ст.
1 МПа = 106 Н/м2
Autonomous roughness recorder ARV-K14
Autonomous roughness recorder ARV-K14. Autonomous roughness recorder uses for autonomous control of roughness on the high seas.
Applications
Autonomous roughness recorder uses for autonomous control of roughness on the high seas. Roughness recorder consists of quarts pressure and temperature transducers PDTK-P-M by SCTB ELPA, frequency counter, semi-conductor memory with electric clock and storage battery, placed in cylindrical stainless steel case. Recorder can be used for the control of relief changing of littoral shelf and destruction of the shore edge.
Features
- Refer to hydrological equipment;
- Having protection from sweet and sea water;
- Completely autonomous during long time (till 400 days);
- High accuracy pressure measurement;
- Stainless steel case.
