YTP - 100 ml/MF seriesThe diaphragm pressure gaugeCan suitable for measuring the corrosive, high temperature, high viscosity, easy to crystallization, easy solidified, has a solid suspended medium pressure and measured medium directly into the universal pressure gauge must be avoided and prevent the sediment accumulation and easy to clean, shall be made by the diaphragm isolator must be used with the universal pressure gauge table to form a system of diaphragm.

Second, the working principle:

YTP - 100 ml/MF series diaphragm pressure gauge is applied to the diaphragm when measuring the pressure of medium P, the diaphragm deformation, compression pressure meter seal fluid pressure system, make its forming P - the pressure of the delta P.When the diaphragm rigid enough hours, the delta P is small, pressure meter pressure system formed nearby for measuring the pressure of medium.

Applications:

YTP - 100 ml/MF series diaphragm pressure gauge is corrosion resistant diaphragm pressure gauge is mainly used for dyeing, alkali, chemical fiber, synthetic fiber, oil chemical industry, alkyl benzene, with chemical dyeing, pharmaceutical, food and cool industrial departments, such as measuring the fluid pressure in the process of production.

Four, the main features:

1, can adapt to the strong corrosion, high temperature, high viscosity medium measurements.

2, has a wide application in the field of industrial production, especially in high temperature, high corrosion environment, diaphragm pressure gauges has played a very important role.

3, when the medium pressure, the pressure of the medium will be through the sealed fluid conduction to the internal pressure gauge, indicates a value was obtained.

4, due to set up a dedicated isolation device, easy to crystallization, so easy to solidification, the solid particles of liquid medium diaphragm pressure gauge measurement may be used.

5, is in the work under the state of the dielectric isolation, so for the diaphragm pressure gauge pressure gauge of manufacturing materials and no special restrictions.

Five, the technical parameters:

1, precision grade: 1.5 on the Richter scale;

2, measuring range: (Mpa) 0 ~ 0.1 0 ~ 0.16 0 ~ 0.25 0 ~ 0.4 0 ~ 0.6 (special specifications when ordering, please indicate);

3, the diaphragm materials: PTFE teflon sheet;

4, internal filling liquid: silicone oil;According to customer needs filling;

5, working conditions: temperature - 20 ~ + 55 ℃ environment temperature;The temperature measured medium - 20 ~ + 55 ℃;

Static load stress: use to three-quarters of the upper limit value of the measurement;

2/3 of the upper limit value of the alternating load, used to measure;

Short-term stress: the upper limit to measure;

6, connection size: threaded connection: M20 * 1.5;Flange connection A, mechanical industry standard JB81-5 "flat steel flange";

B, the ministry of chemical industry standard "weld steel acid-resistant flange";

7, meter diameter (phi phi 100 mm 75 mm).

Six, use and maintenance:

1, the instrument must be installed vertically, handling, installation should avoid collision and vibration;

2, the instrument should be in the ambient temperature of 40 ℃ ~ + 70 ℃, relative humidity is not more than 80% of the venues to use, high temperature use please add a cooling device;

3, meter in the measurement stability load shall not be more than two-thirds of the measurement limit, measuring pressure fluctuations, no more than 1/2 of the upper limit value of the measurement, zui low pressure, in both cases, there should be no less than 1/3 of the upper limit value of the measurement;

4, the corrosive medium, which may be crystallization medium, medium and heavy upheaval fluctuating pressure should be added when the isolation device and buffer device;

5, should be regular inspection (at least once every three months);

6, each time order please specify the medium to be measured, in order to use effect.

Seven, use notice:

1, when using the environment temperature for - 40 ~ 70 ℃, relative humidity is not more than 80%, such as deviation from normal use temperature 20 ℃, the temperature must be included in the additional error.

2, must be installed vertically, and strive to maintain the same level with measuring points, such as the difference between high included in the additional error caused by the liquid column, but don't have to consider when measuring gas.When installation will watch case vent at the back of the jam, lest affect explosion-proof performance.

3, when using normal use of the measuring range: no more than 3/4 of the measurement limit under static pressure, under the volatility should not be more than two-thirds of the measurement limit.In the above two kinds of low pressure situation under large pressure gauge measuring zui should not less than a third of the lower limit, vacuum parts all use measurement of a vacuum.

4, such as when using vacuum gauge pressure failure or internal parts loose, should not work properly when fault repairs, maintenance or production manufacturer.

Eight, selection of code:

Nine, design selection and ordering information:

1, when ordering please indicate the type, name, measuring range, joint thread size, precision grade.

2, if you have special requirements, when ordering, please specify.

3, stainless steel diaphragm pressure gauges diaphragm material choice: in strong acid medium should choose HC HB TA diaphragm, best to four fluorine lining, the strong base class to use 316 l diaphragm.
