gauges - are special devices that are engaged in measuring the pressure.Today there are a large number of them.There are low-pressure gauges, as well as high pressure.Models with temperature scale are classified as thermometers.These devices are used in many areas.First of all they are intended for the study of various natural processes.They also help in determining the pressure of technical devices.Each model has its own class of accuracy.
device
strain gauges in the center of the strain gauge overpressure has a tubular spring.Nearby are Silone, who interact with it.Also, the device has a membrane.There are various kinds.The most common are flat and corrugated membrane.For them, a special gauge box.The sensitivity of the device depends in this case on the stiffness of the spring.The housing can be manufactured in gauges of different materials.
What is a mechanical pressure gauge?
device mechanical gauges is simple.Spring in this device are single-turn.She interacts with the holder, which is located underneath.Also in the gauge set lead a small diameter.It is necessary to consolidate the sector gear.She fastened it to the arrow that indicates the actual performance pressure.
difference electric contact manometer
Inside Electrocontact water pressure gauges have a special leash.He interacts with the arrow tool.The bottom and top of the device features an electric contact.When the pressure is high, the circuit is open.If the index is included in the operating range of the gauge, the alarm system via the arrow shows the deviation.For the position control in the network has a special relay.
gauges bellows
Under the body hides bellows gauge block.Above it there is a silicon-organic liquid.Under a work the bellows unit, which is in contact with the glass.Is it always in the same position.Additionally, the gauge is provided a lever which is connected to the central axis.The rubber rings are arranged on the sleeve.The inner rod running in the device by means of valves.There are two types (isolation and surge).
