Seismic reed electric contact pressure gauge

Vibration-proof reed electric contact pressure gauge not only has the advantages of novel design and…

YXC - 100 - Z seriesAnti vibration reed electric contact pressureTable inherits the traditional electric contact pressure gauge indicates intuitive, convenient adjustment, the advantages of contact without additional power supply, and overcomes the traditional electric contact contact caused bad shortcomings exposed to oxidation.To adapt to different objects and requirements under test, magnetic help electric contact pressure gauge on the basis of the original regular and special, and have developed resistance to vibration, corrosion resistant, corrosion resistance to vibration mode and with a variety of types such as isolation device, a total of more than 10 kinds of models of products.

Second, the working principle:

YXC - 100 - Z seriesAnti vibration reed electric contact pressureThe principle of table type when measured pressure acting on the spring pipe, the end a corresponding elastic deformation displacement of the transmission mechanism, enlarge by indicating device on the dial indicator.Pointer to drive the electric contact 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:

YXC - 100 - Z seriesAnti vibration reed electric contact pressureTables are widely used in petroleum, chemical industry, metallurgy, power stations and other industrial department or mechanical and electrical equipment of form a complete set of measuring no explosion hazard of all kinds of liquid medium pressure.Usually, instrument with corresponding electrical devices (such as relay and contactor, etc.), used in the pressure (control) system to be measured can be automatically, control, and to speak (alarm).

Four, the main features:

1, there are regular and seismic type two kinds of forms, and each have on-site installation and built-in two type;

2, can measure the higher temperature, viscosity is bigger or stronger corrosion medium pressure.

3, magnetic needle on electric contact device of electric contact signal, have adjustable permanent magnets, can increase the contact force and speed up the contact action, so that the contact point contact and reliable, eliminate arc, can effectively avoid the meter caused by environmental vibration or medium pressure pulsation work contact frequently shut off.

4, the instrument has reliable operation, long service life, bigger contact off power, etc.

Five, regular maintenance/repair:

1, after a period of use, and pressure, pressure gauge movement deformation and wear, hard to avoid can appear some pressure gauge can produce all kinds of errors and failures.In order to guarantee the accuracy of its original without distortion, dissemination should be replaced in a timely manner, to ensure that the correct, safe and reliable.

2, pressure gauges need to clean them regularly.Because the interior of the pressure gauge is not clean, will increase the wear parts, thus affecting its normal work, serious can make the pressure gauge failure, scrap.

3, the pressure on the installation of pressure gauge, according to the regulations of JJG52-1999, its verification period is generally not more than half a year.

4 and pressure medium to large fluctuations, used frequently, the accuracy of the demand is higher, and the more strict security factors, according to the specific circumstances will verification cycle shorten appropriately.

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.
