YC series stainless steel differential pressure gauge (hereinafter referred to as instrument) for chemical, chemical fiber, metallurgy, power, nuclear power and other industrial sectors The process of measuring a variety of liquid (gas) medium pressure, flow and other parameters such as Fan and blower pressure, filter resistance, wind speed, furnace pressure, orifice differential pressure, water level and liquid amplifier or hydraulic system pressure . Instrument structure is made of stainless steel, in which the measurement system (double bellows and connecting parts), with strong corrosion resistance and anti-erosion effects of the work environment. Instrument overall design is reasonable, advanced technology, with small size, light weight, Good stability, long service life, novel appearance, strong adaptability, etc. The connection form of the meter connector is flat type (can be directly connected with three valves) and oblique two kinds, which can adapt to different users.
First, the main technical parameters:
1. Differential pressure measuring range, nominal working pressure, accuracy grade and joint thread size:
Differential pressure measurement range | Nominal working pressure | Accuracy class | Joint thread dimensions | ||||||
0~ 10 0~ 16 0~ 25 0~ 40 0~ 60 0~ 100 | KPa | 60 100 160 250 400 600 | KPa | 2.5 | M20 × 1.5 NPT 1/2 | ||||

8. Instrument technical performance in line with enterprise standards Q / YXBM831-1997 "stainless steel differential pressure table"
Second, the structure diagram:
The instrument adopts double bellows structure, in which two corrugated pipes are installed symmetrically on both sides of the 'work' type bracket, and the upper and lower sections of the 'work' bracket are the movable end and the fixed end, respectively, Connection: two bellows parallel to the state, respectively, with the tube on the case of high and low pressure connector is connected: gear transmission directly mounted on the bracket fixed end, and through the rod and the bracket connected to the active end: dial is direct Fixed to the gear transmission mechanism.
Instrument works: Based on the pressure sensor components with the same stiffness of the two bellows, so in the same measured medium to force them to produce the same focus on the activities of the stent, respectively, due to both sides of the spring under the action of torque Does not produce deflection, so the stent is still in the original position, so that the gear transmission mechanism does not move, so that the pointer still refers to the zero position.
When the different pressure (generally high-pressure side is higher than the low-pressure side), the role of the two bellows in the activities of the bracket is not the same force, respectively, to produce the corresponding displacement, and drive the gear transmission and amplification, the pointer deflection Indicating the difference between the two pressure values.
Third, the use of Notes:
1. The instrument shall be mounted vertically at a uniform level to the measuring point. Otherwise, the additional error due to the liquid level difference shall be taken into account.
2. The terminal marked 'H' is the high-voltage end of the meter connector and the low-voltage side labeled 'L'.
3. When measuring the differential pressure, the differential pressure value can be used within 75% of the upper limit of the scale range. The maximum static pressure value of the system should not exceed the maximum static pressure value specified by the instrument.
4. As shown in Figure 4, the installation should be in the instrument before the high and low pressure input to set the balance (safety) valve (valve 1), and should be in the open position, until the valve 2, 3 valve open all the balance valve shut down.
5. Before using the instrument should be carefully verified by the measured medium erosion extent, so as not to cause early corrosion damage to the bellows.
6. Meter in the regular maintenance, such as the table must be opened when the cover should be carried out with special tools.
7. Instrument by the temperature change caused by the increase in indication error and directly affect the accuracy of measurement, you can cut off the case on the protruding pad.
