Choose a 150 mm precision gauge for higher-accuracy checking, a front-flange model for panel installation, or a compact Y-60 for direct local indication. The comparison below shows the dial, connection, accuracy, and pictured-scale details for all four models so you can identify the closest starting point for your application.
Pressure enters through the process connection and deflects an elastic Bourdon tube. A linkage and geared movement amplify that displacement and move the pointer across the dial, giving operators a direct reading at the equipment without an external power supply.
The selected scale determines how clearly the gauge shows normal pressure and expected variation. A scale that is too wide compresses useful movement into a small part of the dial, while a scale that is too narrow leaves insufficient room for operating peaks.
Choose this model when finer reading resolution and higher-accuracy checking matter. Its 150 mm dial provides more space between graduations, its M20×1.5 bottom connection supports direct installation, and its specified accuracy is ±0.4% of full scale.
Choose this model when the three-hole front-flange arrangement shown in the product image suits the panel layout. General Y-100-size gauges use an M20×1.5 connection. The pictured configuration has a dual MPa/psi scale reading 0–1.6 MPa.
Choose this model when the panel layout calls for the three-hole front-flange arrangement in the Y-60ZT format. The pictured configuration has a dual MPa/psi scale reading 0–2.5 MPa. Select between the two ZT models by the required panel format and ordered scale.
Choose this model for compact, direct local indication with a bottom process connection. It has a 60 mm dial and an M14×1.5 connection; the pictured configuration reads 0–2.5 MPa and 0–25 bar.
The selectable pressure range and final mounting configuration must be specified for the order. Pictured ranges describe the photographed configurations, not the complete range offering.
The YB-150B is a 150 mm mechanical gauge for higher-accuracy local indication and checking of general industrial pressure gauges. Its mirrored dial helps the operator align the pointer with the scale when taking a reading.
The Y-100ZT is shown with a round dial and a three-hole front flange for panel installation. It provides a larger-format panel-gauge starting point among the four listed products.
The Y-60ZT is shown with a three-hole front flange for panel installation. Match its panel arrangement and ordered scale to the equipment layout.
The Y-60 is a compact general pressure gauge for direct local indication. Its 60 mm dial fits equipment with limited space, while the bottom connection supports direct installation at the pressure point.
Choose the range from normal operating pressure and the highest credible pressure, including startup conditions and short pressure peaks. For a steady process, placing normal pressure roughly between one-third and two-thirds of full scale is a practical starting point. This keeps normal movement in a readable area while leaving room for expected variation.
Accuracy is expressed relative to full scale, so the selected range affects absolute measurement error. A ±0.4%FS gauge on a 0–0.25 MPa scale has a smaller absolute error limit than a ±0.4%FS gauge on a wider scale. Select the narrowest suitable scale that still accommodates credible operating pressure.
Choose dial units that match the plant standard and make the main unit visually dominant. Dial size and mounting position should let the operator read the pointer at the actual viewing distance without obstructing nearby equipment.
General Y-series gauges are intended for gases or liquids that do not corrode steel or copper alloys and do not crystallize or solidify. The exact gas, temperature, pressure behavior, and contact-material requirements therefore belong in the selection decision.
For corrosive media, oxygen, hazardous locations, vibration, pulsation, or another controlled service, disclose the conditions in the inquiry. For any special-service requirement, include it in the inquiry and require the offered configuration and compliance basis to be stated in writing in the quotation.
The supplier’s standard quality process for pressure gauges includes incoming inspection, assembly checks, appearance and zero checks, indication calibration, sealing verification, final disposition, and record retention.
Indication checks evaluate whether the pointer and dial provide the required pressure reading, while sealing checks examine the pressure-containing assembly for leakage. The applicable method, acceptance criteria, and test conditions depend on the offered model and configuration.
Specify any project-specific test standard, acceptance criteria, witness requirement, or documentation package before production. Internal factory self-inspection records may be requested where available; an internal record is not a third-party inspection or calibration report.
