Far eastone resistance pressure gauge

YTZ - 150 seriesFar eastone resistance pressure gaugeIs through the expression of pressure resistance signals far eastone pressure gauge of the value, its synchronization pressure signal is a resistance value "Ω", hence the name resistance far eastone pressure gauge.It can be connected to the diaphragm separator (diaphragm), made the diaphragm type resistance remote pressure gauge, for measuring the corrosive strong, viscosity is bigger, easy to crystallization medium pressure.
Second, the working principle:
YTZ - 150 seriesFar eastone resistance pressure gaugeThere is a spring tube pressure and a sliding resistance type of transmitter, etc.
The resistance transmitter is set on the gear transmission mechanism, so when the gear drive mechanism in the sector gear shaft of the deviation, the resistance transmitter of the derrick (brush) accordingly to deflection, also because the brush on the resistor, makes the change of the measured pressure value transformation for the change of the resistance, and spread to the secondary instrument, indicating a corresponding reading values.At the same time, an instrument also indicates the corresponding pressure value.

Applications:
YTZ - 150 seriesFar eastone resistance pressure gaugeSuitable for measuring the corrode the copper and copper alloy liquid, gas and steam pressure.Resistance signal output to secondary instrument, can realize the scene in situ indicated pressure for on-site process inspection, and also can realize long-distance centralized control and regulation.

Four, the main features:
1, stable performance, high measurement precision, response speed faster.
2, measuring the total pressure, including gas and steam pressure.
3, the results of the measurement has nothing to do with the gas species, composition and properties.
4, in the process of the pressure, suction and deflated pressure gauge itself is very small, will not affect the measured pressure.
5, no high temperature parts, won't make the oil vapor.
6, if choose corrosion resistant materials, can measure the corrosive gas pressure.
7, firm structure, and sealing and makes the pipes easier to install.
8, easy operation, do not need to adjust, but need to check on a regular basis.

Five, the technical parameters:
1, the precision level: 1.6;
2, the sender starting resistance: 3 ~ 20 Ω;
3, the sender full resistance: 340 ~ 400 Ω;
4, transmitter end connection (1) (2) the applied voltage is not more than 6 v.
5, the sliding resistance type transmitter wiring diagram;
6, the use of environmental conditions: 40 ~ 60 ℃, relative humidity is not more than 85%, of measured medium (control) and vibration and sharp pulse response not significantly affect the normal work of the instrument;
7, humidity impact: when using the temperature deviation from 20 + / - 5 ℃, the temperature additional error is not more than 0.4% per 10 ℃;
8, weight: 1.2 kg.

Six, use notice:
1, when using the environment temperature for - 40 ~ 70 ℃, relative humidity is not more than 80%, such as deviation from normal use temperature 20 ℃, the temperature must be included in the additional error.
2, must be installed vertically, and strive to maintain the same level with measuring points, such as the difference between high included in the additional error caused by the liquid column, but don't have to consider when measuring gas.When installation will watch case vent at the back of the jam, lest affect explosion-proof performance.
3, when using normal use of the measuring range: no more than 3/4 of the measurement limit under static pressure, under the volatility should not be more than two-thirds of the measurement limit.In the above two kinds of low pressure situation under large pressure gauge measuring zui should not less than a third of the lower limit, vacuum parts all use measurement of a vacuum.
4, such as when using vacuum gauge pressure failure or internal parts loose, should not work properly when fault repairs, maintenance or production manufacturer.

Seven, selection of code:

Eight, design and ordering information:
When ordering, please specify the name of the measured medium, working pressure, medium temperature and medium density, measuring range, installation method, etc.
