yxc series magnetic electric contact pressure gauge -尊龙登录

magnetic electric contact pressure gauge is used to measure the pressure of liquid without explosion danger, crystallization, or corrosion on alloy. applied with the corresponding electric device, the instrument can achieve the double purposes of automatic controlling and warning of the measured pressure        system. 
the instrument has a measure-control function, so it can arbitrarily set the upper or lower control pressure. the operation is stable and electric. it can be widely used in the petroleum, chemical, power plants, metallurgical and other industrial enterprises.
structure & theory:
the instrument consists of the measurement system, indicating devices, magnetic electrical contacts devices, the outer casing, adjusting device, junction box and other components.
when the measured pressure acts on the spring tube, it will produce the corresponding elastic deformation at the end part - displacement. amplified by the transmission device, it will be showed on the reading device by indicating device.
meanwhile, the pointer drives the movable contactor on the electric contact set, then contacts with the predefined pointer. when the two pointers meet, the control system switches on or off the current circuit to achieve automatic control or to send a single to warn.  
there is a permanent magnet, which can be adjusted, on the electrical contact signal pin of the electric contact device. it can increase the suction of the contacts and can speed up the action. it will make sure that the contact is stable, the arc is eliminated. it also can effectively avoid the frequent contacts off of the instrument as a result of vibration or media environment pressure fluctuation. so the instrument has many advantages, such as, electric action, long life, greater power contact switch, etc..
