Anticorrosion all plastic diaphragm pressure gauge

S series YTP - 100Anticorrosion all plastic diaphragm pressure gaugeIs the introduction of general diaphragm pressure gauge according to user's requirements on the basis of advanced technology development and design of new varieties.Main components of the diaphragm connection with PVS PVC materials, diaphragm is made of PTFE teflon), adopt the phenolic plastic membrane, has good anti-corrosion performance, suitable for measuring the corrosive gas, such as hydrochloric acid has strong corrosion of gas or liquid pressure.

Second, the working principle:

YTP - 100 - s series anticorrosive all plastic diaphragm pressure gauge by measuring system (including joints, corrugated bellows, etc.), drive mechanism (including the pull rod, gear transmission mechanism), indicating device (including a pointer and dial) and the shell (including casing, lining and table glass).

Is based on the corrugated bellows under pressure measured medium, its free end produce elastic deformation, then through a pull rod and amplification, transmission gear transmission mechanism by pointer fixed on gear shaft by measured values will be indicated on the dial out.

Three, the main features:

1, many pressure range, can better adapt to the request of the customer.

2, the price is low, can save cost for you.

3, beautiful appearance, more can reflect the value of your equipment.

4, installation is convenient, flexible disassembly.

5, simple maintenance, stable performance.

Four, the technical parameters:

1, precision grade: 1.5 on the Richter scale are unlikely

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:

(1) silicone oil;

(2) fill according to customer's requirements.

Five, the working conditions:

1, temperature, environment temperature - 20 ~ + 55 ℃ temperature measured medium - 20 ~ + 55 ℃.

2, working pressure: static load: use to three-quarters of the upper limit value of the measurement;

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

4, short-term pressure: used to measure threshold.

Six, connection size:

1, threaded connections: M20 * 1.5 (G3/8 "G1/2").

2, flange connection A: mechanical industry standard JB81-5 flat steel flange.

3, our factory standard flange.

4, customized according to user needs.

Meter diameter (75 mm) phi phi 100 mm.

Seven, use and maintenance:

1, the instrument must be installed vertically: should be used when the wrench to tighten, should not sell table head;Transportation should avoid collision.

2, instrument use appropriate in the ambient temperature is 25 ~ 55 ℃."

3, the use of the work environment vibration frequency < 25 hz, the amplitude is not more than 1 mm.

4, instrument use scope, should be between the upper limit of 1/3 to 2/3.

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 case of the above two kinds of pressure big pressure gauge measuring the lowest lower limit should not be less than a third of all, measuring the vacuum vacuum parts all use.

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

5, when using, should avoid vibration and impact, so as to avoid damage.

Nine, specifications:

Ten, ordering information:

1, when ordering please indicate the type, name, precision grade, measurement range, joint thread size;

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.

4, after the warranty period appear quality problem, my company is responsible for, such as user need to my company site service, maintenance, for use in the province for damaged parts cost.My family company service personnel to reach the site within 12 hours, fujian association of foreign languages and user reach the site within 48 hours.
