Health type diaphragm pressure gauge

• 

Health type diaphragm pressure gauge is the whole health level of stainless steel diaphragm pressure…

MC series YTP - 100Health type diaphragm pressure gaugeBased on clamp installation whole health level of stainless steel diaphragm pressure gauge.Is suitable for measuring high viscosity, easy to crystallization, easy to solidification and have solid suspended matter medium pressure, and for some measurement medium can not directly into the universal pressure gauge and the place where the easy cleaning to prevent precipitation pressure test, must be used by the diaphragm isolator and universal pressure gauge table to form a system of diaphragm.Applicable to beer, beverage and other food and pharmaceutical industries.

Second, the working principle:

MC series YTP - 100 type health diaphragm pressure gauge by all sorts of general and different structure diaphragm type pressure gauge isolator to form a closed system, filled with sealing liquid.When the measured medium pressure acting on the diaphragm, diaphragm deformation, compression sealing fluid in a closed system.Due to the inherent nature of sealing fluid, make the elastic element of pressure gauge produces corresponding elastic deformation, displacement, by indicating device shows pressure value.When the enough stiffness of the diaphragm, pressure meter indicating pressure near the measured medium pressure value.

Applications:

MC series YTP - 100 type health diaphragm pressure gauge is composed of universal pressure gauge and the diaphragm isolator a system of diaphragm pressure gauge.At the scene of the technology of quick and convenient installation, not pollution, easy to clean, safe and reliable.To meet the requirements of production quality standard (GMP).In the pharmaceutical, food, beverage, water treatment and other industries for instrument is widely used in the process of health requirements.

Four, the main features:

1, the temperature characteristic

Because the diaphragm table filled the sealing liquid system as the pressure transmission medium, and the quantity of the diaphragm table temperature sealing liquid coefficient of expansion and compression of diaphragm stiffness and parts related to the temperature.Temperature gauges are used in deviated from its 20 + / - 5 ℃, particularly for the influence of low range pressure gauge.General compression zone temperature error is not more than 1.0% / ℃, so the temperature of the diaphragm table is generally by the universal pressure gauge temperature affects measure and diaphragm separator compression zone temperature influence both combined.

2, poor level

Especially for diaphragm table with soft connecting pipe, because the diaphragm compression zone and universal pressure gauge installation position is not in the same horizontal plane, will produce the effect of liquid level difference, more attention should be paid to in precise measurement.

3, the corrosion resistance

Diaphragm table of corrosion resistance can be suitable for the selection and measurement of media contact part of the diaphragm, the flange and the sealing gasket materials to ensure that.

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, PTFE teflon sheet diaphragm material;

4, internal filling liquid silicone oil (1);(2) fill according to the requirements of clients;

5, working conditions: (1) the temperature - 20 ~ + 55 ℃ environment temperature;The temperature measured medium - 20 ~ + 55 ℃;

(2) static load stress: used 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 (1) threaded connection, connection size: M20 * 1.5 (G3/8 "G1/2").

Sixth, the choice of materials:

1, the diaphragm material: 316;316 l;Monel alloy, hartz alloy, tantalum, and fluorine plastic.

2, flange material: stainless steel 304, 316;Stainless steel lined with fluoroplastic (316 + F4).

Sealing gasket material: rubber;Fluorine rubber;Silicone rubber and fluorine plastic.

3, diaphragm liquid choice: in strong acid medium should choose HC HB TA diaphragm, four fluorine lining, the strong base class to use 316 l diaphragm.

Seven, the diaphragm liquid choice:

Eight, use the matters needing attention:

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.

Nine, specifications:

Ten, 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.

After-sales service commitment:

1, our company sold by pressure gauge series product appeared quality problem within 12 months, responsible for free maintenance.

2, the warranty period, any quality problems such as the products of our company, my company is responsible for free repair or replacement.

3, the warranty period, such as user improper use, damaged products, my company is responsible for the maintenance, charge damage parts cost.
