The difference and relation between the electric contact pressure gauge and the remote pressure gauge
The electric contact pressure meter is suitable for measuring the pressure of copper, alloy free of corrosion, explosion free, non crystallization of various liquids, gases and other media. When the electric contact manometer is used in conjunction with the corresponding electrical device, the two bit automatic control and sending (alarm) of the maximum or minimum pressure preset to the pressure system under test can be achieved. The electric contact pressure gauge has the function of measuring and controlling. It can freely set up the upper and lower control pressure values. The operation is stable and reliable. It is widely used in petroleum, chemical, power stations, metallurgy and other industrial enterprises and electromechanical equipment.The resistance remote pressure gauge consists of a spring tube, a pressure gauge, a slide wire, a resistance transmitter, etc..The function principle of the mechanical part of the pressure gauge is similar to that of the spring tube manometer. Because the resistance transmitter is arranged on the gear drive, so when the fan gear shaft gear transmission mechanism of deflection, rotating arm resistance transmitter (brush) corresponding to the deflection, brush sliding on the resistor, the change of the measured pressure is changed into a resistance value, and at the two time the meter, indicating a corresponding reading value. At the same time, the primary instrument also indicates the corresponding pressure value.
The use of the two is different. One is used to control the other, and the other is to send the signal to the farther end of the monitor.The electric contact pressure gauge consists of measuring system, indicating system, magnetic auxiliary contact device, shell, adjusting device and junction box (plug seat), etc.. The working principle of electric contact pressure gauge is spring pipe in the measuring system under the action of the pressure of the measured medium based on the force generated by the end of spring pipe corresponding elastic deformation displacement transmission rod through a gear transmission mechanism with the help and amplification by the fixed gear instructions (along with contact) by the measured value indicated in the table. At the same time, when the contact and set on the pointer (upper or lower) contact (break or close) instantaneous, resulting in the circuit control system can be switched on or off in order to achieve the purpose of automatic control and alarm.The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy. Because the resistance transmission pressure gauge is arranged inside the sliding line resistance transmitter, so the measured values of two meters on electricity to far away from the measurement, in order to realize centralized monitoring and remote control. In addition, the pressure gauge is capable of indicating pressure in place so as to facilitate on-site inspection.
Maybe you don't understand the downstairs, generally speaking:The difference between the electric contact pressure gauge and the remote pressure gauge:1, the electric contact pressure gauge is to choose an interval, the pressure value can work in this interval, reached the boundary point will call the police.2, remote pressure gauge can be understood, is a common pressure gauge, which will produce changes in the resistance signal, then the signal is transmitted to a far place, such as the front, I don't have to look at the pressure gauge at the scene. The obvious difference.?The connection of the electric contact pressure gauge with the remote pressure gauge:To say the connection between the two is the electrical signal (but the former is the control point, the path is broken, and the latter is the output of its change). They're all pressure gauges. Still do not understand the Q asked me 414536922 one figure a remote pressure gauge, assembly, electric contact pressure gauge, the appearance is different from.
