Electric contact pressure gauge widely used in petroleum, chemical, metallurgical, power plant, machinery and other industrial departments or mechanical and electrical equipment of form a complete set of measuring various fluid medium pressure explosion hazard. Usually, the instrument with corresponding electrical devices (such as relay and frequency converter, etc.), the (control) the pressure to be measured can be all kinds of gas and liquid medium by the instrument to achieve automatic control and transmitting (alarm).

1 the product application
In electrical contact signal pin on electric contact pressure gauge unit, equipped with 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 instrument due to working environment vibration or medium pressure pulsation contact frequently shut off. So the electric contact pressure gauge has reliable operation, long service life, bigger contact switch power, etc. 2 structural principles
Electric contact pressure gauge by measuring system, indicator system, magnetic electric contact device, housing, adjustment device and junction box (socket), etc. General electric contact pressure gauge is used to measure the gas do not corrode copper and copper alloy, the positive and negative pressure of liquid medium, stainless steel electric contact pressure gauge with ?

6 product categories
In view of this series instrument not only has the advantages of novel design and reliable in structure, variety specification is complete, the action, 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 the difference in general instructions, switch adjustment and without the pressure setting device, the incomparable pressure measurement and control instrument.
In order to satisfy the different of measured object (such as seismic or corrosion resistance and the explosion-proof requirements), can be used in accordance with requirements of seismic electric contact pressure gauge or corrosion electric contact pressure gauge and explosion-proof electric contact pressure gauge,
Explosion-proof electric contact pressure gauge
7 electrical principle
To control the compressor motor as an example: gas filling and pressure to automatically open, upper reaches the maximum of automatic stop.
Control process is as follows: the arrival of the pressure or low when the phone is switched on and the lower limit, the activities of the electric contact pressure gauge contact (common power supply), connected with the lower contact and latching relay J1 movements, the normally open contacts closed drive J3, motor electric operation. When the pressure reaches the ceiling, the activity contact with ceiling contactor connected, relay J2 action, the normally closed contacts disconnect, cut off the power supply, J1 it normally open point off, J3 release, motor stalling. So, to achieve the purpose of automatic control.
8 by liquid material
The material of electric contact pressure gauge is: copper alloy, stainless steel 304 or 316 stainless steel.
9 verification
1. Electric contact pressure gauge is actually gauge control circuit switch, is only one more on normal pressure gauge electric contact signal device, as a result, the pressure of calibration and verification of ordinary pressure gauge is the same, only a partial certified pressure, still need to increase the verification for the electric contact signal device.
2. The electric contact pressure gauge verification steps
The pressure gauge mounted on a validator, with dial needle detector respectively two signal contact pointer to the upper limit and lower limit, then value for verification. Certified value, the upper and lower limits of the signal contact pointer is scheduled for more than three different check point, slowly increase or reduce the pressure, until the signal instantaneous, then the standard pressure gauge pointer ? value for reading and signal
10 common problems
The electric contact pressure gauge of signal either early or late:
Is contact malposition or contact metal rod is loose. Contact malposition, vertical to the appropriate contact calibration signal. Loose contact metal bar, should try to solid, mild, adopt appropriate balance spring to enlarge, increase the torque balance spring, also have the effect.
Electric contact device without signal: contact too dirty poor contact; Signal device insulation be affected with damp be affected with damp; Circuit impassability, etc. Contact is too dirty, use sandpaper to remove dirt; Insulating layer be affected with damp be affected with damp, hot air blow dry; Should look for open circuit circuit impassability, and repair.
