Q1: What is a stainless steel pressure gauge?
A: A stainless steel pressure gauge is a mechanical instrument that uses a stainless steel Bourdon tube as the sensing element to measure pressure. The pressure causes the tube to deform, and this mechanical movement is transmitted through a gear mechanism to a pointer that indicates the pressure on a dial[reference:63]. The housing, internal mechanism, and wetted parts are all made from corrosion-resistant stainless steel materials[reference:64].
Q2: What are the main types of stainless steel pressure gauges?
A: The main types include: YBF Series — standard stainless steel pressure gauge[reference:65]; YBFN Series — stainless steel vibration-resistant (liquid-filled) pressure gauge[reference:66]; Y-100B Series — standard all-stainless steel pressure gauge[reference:67]; and YN Series — vibration-resistant versions[reference:68].
Q3: What is the difference between YBF and YBFN pressure gauges?
A: YBF is a dry-type stainless steel pressure gauge with vibration resistance grade V.H.3[reference:69]. YBFN is a liquid-filled (glycerin) vibration-resistant pressure gauge with vibration resistance grade V.H.4[reference:70]. The YBFN is recommended for high-vibration environments and pulsating pressure applications where glycerin filling effectively dampens pointer fluctuations[reference:71][reference:72].
Q4: What standards do your stainless steel pressure gauges comply with?
A: Our stainless steel pressure gauges are manufactured in compliance with GB/T 1226-2017 (Chinese national standard for general pressure gauges)[reference:73], IEC 61518, and ASME/ANSI B40.1 (American standard)[reference:74].
Q5: What accuracy grades are available?
A: We offer three accuracy grades: ±1.0% (premium grade for critical applications), ±1.5% (standard grade for most industrial applications), and ±2.5% (economy grade for general monitoring)[reference:75][reference:76].
Q6: What dial diameters are available?
A: Standard dial diameters include 60mm, 100mm, 150mm, and 200mm[reference:77][reference:78]. The 100mm and 150mm sizes are the most commonly used for industrial applications.
Q7: What materials are used in stainless steel pressure gauges?
A: Housing: 304 or 316 stainless steel[reference:79][reference:80]; Bourdon tube: 304 or 316 stainless steel[reference:81]; Movement/gears: 304 or 316 stainless steel[reference:82]; Wetted parts: 1Cr18Ni9Ti, OCr18Ni12Mo2Ti, or SUS316[reference:83][reference:84].
Q8: What pressure ranges are available?
A: Pressure ranges include: Vacuum: -0.1~0 MPa; Compound: -0.1~0.15, -0.1~0.5, -0.1~2.4 MPa; Positive pressure: 0~0.1 up to 0~60 MPa[reference:85]. High-pressure versions up to 160 MPa are also available[reference:86].
Q9: What process connections are available?
A: Standard connections include M20×1.5 (most common), M14×1.5, G1/4, G1/2, and 1/2 NPT[reference:87][reference:88]. Custom threads are available upon request[reference:89].
Q10: What are the temperature limits for stainless steel pressure gauges?
A: Ambient temperature (dry type): -40°C to +70°C[reference:90][reference:91]; Ambient temperature (liquid-filled): -25°C to +70°C[reference:92][reference:93]; Process temperature: Depends on the model — for high-temperature applications, a cooling siphon or diaphragm seal is recommended.
Q11: What is the vibration resistance of stainless steel pressure gauges?
A: Dry type (YBF): V.H.3 vibration resistance grade[reference:94]; Liquid-filled type (YBFN): V.H.4 vibration resistance grade[reference:95][reference:96]. The liquid-filled version provides superior damping for high-vibration and pulsating pressure applications.
Q12: What filling media are used in vibration-resistant pressure gauges?
A: The standard filling medium is glycerin (98%)[reference:97][reference:98]. Silicone oil and fluor oil are also available as alternatives for specific applications[reference:99].
Q13: What are the mounting options?
A: Radial direct mount (bottom connection) — standard for most applications[reference:100]; Axial (back connection) — for panel mounting[reference:101]; Front flange and rear flange options are also available[reference:102].
Q14: What IP protection levels are available?
A: We offer multiple ingress protection levels: IP54 — dust-protected and splash-proof; IP55 — dust-protected and jet-proof; IP65 — dust-tight and jet-proof (recommended for harsh environments); IP66 — dust-tight and powerful jet-proof[reference:103].
Q15: How do I select the correct pressure range for my application?
A: For steady pressure, the maximum operating pressure should not exceed 2/3 of the full scale. For pulsating pressure, it should not exceed 1/2 of the full scale. For high pressure, it should not exceed 3/5 of the full scale. The minimum measured pressure should be no less than 1/3 of the full scale[reference:104].
Q16: What are the typical applications of stainless steel pressure gauges?
A: Stainless steel pressure gauges are widely used in: Power plants — boiler pressure, turbine oil pressure; Petrochemical — reactor pressure, pipeline monitoring; Oil & gas — wellhead pressure, refinery processes; Food processing — sanitary pressure measurement; Water treatment — pump discharge pressure; EPC projects — instrumentation and control systems[reference:105][reference:106].
Q17: What is the difference between 304 and 316 stainless steel for pressure gauges?
A: 304 stainless steel is the standard material for most industrial applications, offering good corrosion resistance[reference:107]. 316 stainless steel offers superior corrosion resistance, especially against chlorides and acidic media, and is recommended for marine environments, chemical processing, and pharmaceutical applications[reference:108][reference:109].
Q18: What tests are performed on stainless steel pressure gauges before delivery?
A: We conduct comprehensive quality tests including: (1) Accuracy test — verifying linearity and repeatability; (2) Pressure test — verifying overpressure capability; (3) Leak test — verifying seal integrity; (4) Insulation resistance test; (5) Temperature effect test — verifying temperature compensation; and (6) Vibration test — for liquid-filled models.
