Reed Switch Electric Contact Pressure Gauge
Application
The pressure gauge is suitable for measuring the pressure of non- crystalline, non-solidified and non-explosive media. It is used in conjunction with electrical devices (such as relay, contactor, PLC, etc.) to pre-set the maximum or minimum pressure value and achieve automatic control and signal (alarm) purposes for the controlled system. It has measurement and control functions, and the upper and lower limits of the controlled pressure can be set according to needs. It is widely used in petroleum, chemical, power station, metallurgy, water supply and other industries, as well as electromechanical equipment.
Features
Reed switch electric contact pressure gauge can transmit signals well under low voltage (24V, 12V) without arcing phenomena. It has fast response speed and long service life. Its advantage is that the contact switch is isolated from the atmosphere, and there is noble gas or vacuum state in the tube, which can reduce the oxidation and carbonization of the contact. The sealed design can prevent external steam and dust impurities from corroding the contact. The reed switch.

Operation
■The wiring operation should be carried out by a qualified electrician.
■When debugging or switching the control section, the control circuit should be disconnected, and the power can be turned on after the operation is completed.
■Reed switch electric contact pressure gauge must be used in a low voltage control environment within the specified technical range. Otherwise it will cause contact damage.
■Please read the instructions carefully before use.
■It is necessary to add a protective device for the pressure gauge in an environment with a sharp pressure change or vibration or pulsation.
■When installing or disassembling, don't pull the case of the gauge by hand, use a special wrench to install or disassemble.
■To measure oxygen, acetylene or other flammable gases, pressure gauges with oil prohibition signs should be used.
■Please use Hakin special medium pressure gauge when measuring the medium that is explosive or corrosive, easy to crystallize or solidify.
■The pressure gauge should be installed horizontally or vertically.
