Products overview:

YXC - 100 seriesMagnetic type electric contact pressure gaugeNot only has the advantages of novel design and reliable in structure, variety complete, the characteristics of good stability and strong adaptability, and a measurement and control and the advantages of small, simple installation and maintenance, therefore, it is no instructions, no switch generally poor adjustment and without the pressure setting device, the incomparable pressure measurement and control instrument.

Second, the working principle:

YXC - 100 seriesMagnetic help type electric contact pressure gauge by measuring system, indicator system, magnetic electric contact device, housing, adjustment device and junction box (socket), etc.

Instrument working principle is based on the measurement system of bourdon tube under the action of the pressure of tested medium, after the end of spring tube to produce a displacement of the corresponding elastic deformation with rod and to amplify the transmission gear transmission mechanism, by the direction on the fixed gear (along with contact) by the measured value on the dial indicator.At the same time, when its contact and setting a pointer (upper or lower limit) contact (broken or move) instantaneous, led to the disconnection or connection of control circuit in the system, in order to achieve the goal of automatic control and transmitting alarm.

Applications:

YXC - 100 seriesMagnetic help type electric contact pressure gauge widely used in petroleum, chemical, metallurgical, power plants and other industrial departments or mechanical and electrical equipment of form a complete set of measuring various fluid pressure explosion hazard.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.
