XG/YE-100、 150 series diaphragm box pressure gauge

XG/YE-100、150 series diaphragm box pressure gauge is a local micro-pressure-indicating mechanical pressure gauge that uses a corrugated membrane box as the pressure-sensing element. The gauge diameter is divided into two specifications: Φ 100mm and Φ 150mm. By relying on the corrugated film box to generate elastic displacement under pressure, the displacement is amplified by the lever gear transmission mechanism, and the pointer is driven to achieve on-site micro pressure, negative pressure, and positive and negative pressure display. The ordinary version of the liquid film box and joint are made of copper-tin alloy; The suffix - B is the stainless steel version, and the liquid receiving parts are replaced with stainless steel material; expandable shock-resistant and magnetic-assisted electrical contact configuration, suitable for measuring gas micro pressure and negative pressure without explosion hazard, commonly used in boiler ventilation, gas, furnace, dust removal fan, and other working conditions.

Product advantages:
1. The sensitivity of micro pressure measurement is high, and the membrane box pressure sensing element is sensitive to small pressure changes, making it specifically suitable for micro pressure and low-pressure gas measurement scenarios.
2. Excellent airtightness performance, welded sealing structure, anti-gas leakage, commonly used for monitoring gas pressure such as furnace air pressure, gas, ventilation, etc.
3. Lightweight and stable structure, simple internal structure, superior overload resistance compared to some spring tube instruments, and low daily failure rate.
4. The optional configuration is rich, and it can be made into stainless steel, shock-resistant, and magnetic-assisted electrical contact versions to achieve on-site alarm interlocking. The interface is diverse and easy to install and debug.                                                  

Main selling points:
1. Sensitive micro pressure measurement, membrane box pressure sensing element, skilled in low-pressure and micro pressure gas detection, fast response to small pressure changes.
2. Good airtightness, welded sealing structure, gas leakage is not easy, suitable for gas working conditions such as wind pressure, gas, furnace ventilation, etc.
3. Simple structure with a low failure rate, capable of withstanding certain overload, lightweight, and reliable for long-term operation.
4. Multiple configurations are available, supporting stainless steel, shock-resistant, and magnetic-assisted electrical contact styles to achieve pressure alarm interlocking control.
5. Easy installation and maintenance, complete interface specifications, easy disassembly and replacement, widely compatible with various types of fans, boilers, and gas equipment.

FAQ Performance Specifications

Q1: Can a bellows pressure gauge be used to measure liquid media?
A: Mainly used for measuring gas micropressure and low pressure; it is not recommended for measuring liquids. Liquid entering the membrane box cavity can easily cause internal corrosion and zero drift; It is recommended to use diaphragm or spring tube pressure gauges for measuring liquid media.

Q2: Why is the range of the bellows pressure gauge so small? Can it measure high pressure?
A: The membrane box is a thin-walled pressure-sensing element, only suitable for micro pressure and low pressure. High pressure can cause permanent deformation of the membrane box and instrument failure; Please use a spring tube pressure gauge for high-pressure conditions.

Q3: How to choose between a regular diaphragm box and a stainless steel diaphragm box pressure gauge?
A: The ordinary diaphragm box overcurrent component is made of copper alloy, suitable for dry and non-corrosive gases; If there is weakly corrosive gas and a humid environment, a stainless steel diaphragm box pressure gauge can be directly selected to improve the anti-corrosion service life.

Q4: What are the reasons for the pointer not returning to zero and inaccurate measurement?
A: Main causes: overpressure impact, corrosive gas corroding the membrane box, frequent pressure fluctuations. Do not overload, choose stainless steel for corrosive media, regularly check the zero point, and replace the instrument immediately when the membrane box is severely deformed.
