Precision pressure gauge _ _ Huachen Instruments

(Needle gauge) needle gauge refers to the so-called double-tube pressure gauge needle, it is a more typical special gauge. This instrument has two test object interface, it can simultaneously access two measured object precision digital pressure gauge pointer by the separation of the measured object at the same time indicate the two respective pressure. Especially for the two readings of the alignment need to be measured. The internal structure of needle gauge pressure gauge is also very characteristic, it skillfully, which combines two measuring electrical contacts, and each independently. The two independent measurement bodies and their own drag the pointer on the same dial direct their respective pressures. Effectively from the indicator device minimizes error ratio, significantly increased the ratio of the two measured object precision pressure gauge readings by measuring precision accuracy, it can be divided into precision pressure gauges, general pressure gauge. Precision pressure gauge measurement accuracy rating was 0.1,0.16,0.25,0.4 level; general gauge measurement accuracy is usually 1.0,1.6,2.5 level. Meter accuracy level of the basic error limit is determined by the rest of the range except for the measurement of more than 90% of the basic error limit based on meter range and level of accuracy, error calculation by reference. Such as 0 ~ 6MPa, 1.6 class instrument gauge accuracy class, the basic error limit of ± (6 × 1.6%) MPa = ± 0.096MPa. Pressure gauge indicates the pressure at different benchmark, divided gauge, absolute pressure gauge, differential pressure gauge. General gauge to atmospheric pressure measurement reference; absolute zero absolute pressure gauge to the measurement reference; differential pressure gauge measuring the difference between the two measured pressure (pressure gauge) ordinary pressure gauge (referred to as "the general pressure gauges") It is the most basic type of gauge. Its series of complete, simple structure, reliable performance, indicating intuitive, low cost, is the most widely used gauge precision pressure gauge _ _ Huachen instruments provided by the Instrument Co., Ltd.
