Potentiometer far eastone pressure gauge

YTZ - 150 seriesPotentiometer far eastone pressure gaugeThe role of mechanical parts is the same as the general bourdon tube pressure gauges.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.
Second, the working principle:
YTZ - 150 seriesPotentiometer far eastone pressure gauge(including joint, bellows) by measuring system, transmission mechanism, indicating device, magnetic electric connection device, shell, conditioning and air stand, etc.
When the measured medium pressure acting on the bellows, the free end of corresponding elastic deformation, displacement, amplified by pull rod drive transmission mechanism, by indicating device will be measured pressure on meter dial indicator.Pointer to drive the electric connection device at the same time contact and setting a pointer on the contactor (upper or lower limit) of the instantaneous contact, led on or off circuit control system, to achieve the goal of automatic control and transmitting alarm.

Applications:
YTZ - 150 seriesPotentiometer far eastone pressure gaugeIn almost all industrial processes and scientific research.In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere.Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used.

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:
Precision level: 1.6;
Sender starting resistance: 3 ~ 20 Ω;
The sender full resistance: 340 ~ 400 Ω;
Transmitter end connection (1) (2) the applied voltage is not more than 6 v.
Sliding resistance transmitter type wiring diagram;
Environmental conditions of use: 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;
Humidity impact: when using the temperature deviation from 20 + / - 5 ℃, the temperature additional error is not more than 0.4% per 10 ℃;
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.
