Process Connection :G ½ B Others on request
Permissible Temperature :

Ambient :  ■ -40 … +60 °C [-40 ... +140 °F] with unfilled instruments          ■ -20 … +60 °C [-4 ... +140 °F with instruments with glycerine filling (model 333.50)

Medium :  ■ +200 °C [+392 °F] maximum with unfilled instruments            ■ +100 °C [+212 °F] maximum with filled instruments (model 333.50)

Temperature Effect :When the temperature of the measuring system deviates from the reference temperature (+20 °C): max. ±0.4 %/10 K of full scale value
Pressure limitation:

Steady --Full scale value 

Fluctuating-- 0.9 x full scale value 

Short time-- 1.3 x full scale value

 

  

Applications:

■ With liquid-filled case for applications with high dynamic pressure loads or vibrations

■ For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments

■ Precision measurement in laboratories

■ High-accuracy pressure measurement

■ Testing of industrial type pressure gauges

■ Precision pressure gauge is mainly used to check the general pressure gauge and used for precise measurement pressure which do not corrode copper and its alloy liquid ,gas, also can be used to pressure measuring instruments and meters and other kind of instrument calibration and test which is a certain function relation .

 

Theory:

Precision pressure gauge is made of measuring system (including joint , wave tube , etc.), drive mechanism ( including rod, gear transmission mechanism), indicating device ( including a pointer and dia) and the shell (including casing ,lining, and table glass), the elastic element is through special craft processing , cooperate with special machine core components , combination of both. 

Precision pressure gauge works theory is that when the measured medium pressure acting on the elastic element makes its produce elastic deformation displacement , amplified by rod drive transmission mechanism , the measured pressure by indicating device instructions.

 

Special features:

■ Completely from stainless steel

■ Knife edge pointer for optimal accuracy of reading

■ Wear-resistant precision movement from stainless steel

■ Scale ranges from 0 … 0.6 to 0 … 1,600 bar [0 ... 10 psi to 0 ... 20,000 psi
