Thermocouple alloy and junction selection
Guage Pressure: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
The archived configuration for Guage Pressure lists Process connection: φ 60 M14 * 1.5, other M20 * 1.5 can be customized; Liquid receiving material: Copper alloy, 304SS, 316L customizable; Case Material: Carbon steel spray molding, 304SS, 316L optional. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For Guage Pressure, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of Guage Pressure depends on the assembled equipment and agreed operating conditions.

Definition and Working Principle
A stainless steel pressure gauge is a mechanical pressure measuring instrument where the wetted parts and case are mostly made of stainless steel (such as 304, 316/316L). Its core component is the Bourdon tube: when the pressure of the medium acts on the tube, it causes elastic deformation, which is amplified by a gear transmission mechanism to drive the pointer to indicate the pressure value on the dial. For vibration-resistant models, glycerin or silicone oil is filled inside to dampen vibration and cushion shocks.
Main Components:
Bourdon tube (316/316L is the preferred choice for corrosion resistance)
Gear transmission mechanism
Pointer and dial
Stainless steel case (304 is common; 316 is preferred for coastal/chemical environments)
Threaded connection (M20×1.5 is the industrial standard)
Seals (FKM fluororubber, PTFE for highly corrosive media)
Common Classifications
By Function:
Standard stainless steel pressure gauge (non-liquid-filled)
Vibration-resistant stainless steel pressure gauge (liquid-filled for anti-vibration, suitable for pumps and construction machinery)
Diaphragm-seal stainless steel pressure gauge (isolates viscous/crystallizing/highly corrosive media, with flange/sanitary clamps)
Explosion-proof stainless steel pressure gauge (Ex-certified for flammable and explosive areas)
By Installation:
Radial (direct pipe mounting)
Axial (panel mounting)
Radial/Axial with mounting bracket
By Range:
Positive pressure gauge (0~X MPa)
Negative pressure/vacuum gauge
Compound pressure-vacuum gauge (e.g., -0.1~1.6 MPa)
Key Selection and Range Principles
Medium: Corrosive media → 316L; viscous/crystallizing media → diaphragm type; pulsating pressure → vibration-resistant liquid-filled model with 1.5~2x range.
Range: For stable pressure, select a full scale 1.5 times the working pressure, not exceeding 2/3 of the full scale; for pulsating pressure, ≤1/2 of the full scale; for high pressure, ≤3/5 of the full scale.
Accuracy Class: 1.6 is common for industrial use; 1.0 or 0.5 for precision control. Operating temperature range: -40~80°C; high-temperature models require heat-resistant seals and elements.
Connection: M20×1.5 (metric), G1/2, NPT1/4 (imperial/American).
Application Areas
Petrochemical, metallurgy, water treatment, food and beverage, pharmaceuticals, marine, power generation, refrigeration, and printing and dyeing. It is especially suitable for scenarios with corrosion, vibration, and high hygiene requirements, replacing ordinary copper alloy pressure gauges.
VI. Installation and Maintenance Points
Installation: Avoid direct sunlight, vibration sources, and strong electromagnetic interference. For diaphragm gauges, ensure the fill fluid is compatible with the medium. Mount vertically to ensure accuracy.
Calibration: Regularly calibrate at a metrology institute (usually annually; shorten the interval for harsh conditions).
Daily Use: Strictly prohibit overpressure operation. If the pointer enters the yellow/red zone, troubleshoot immediately. Regularly inspect seals and appearance in corrosive environments.
