Product Introduction

The YB Series Precision Test Pressure Gauge is a mechanical pressure instrument designed for accurate pressure indication in laboratory testing, pressure inspection, and industrial measurement applications.

It uses a stainless steel Bourdon tube as the pressure sensing element. When pressure enters the tube, its elastic deformation is transmitted through a precision mechanical movement to the pointer, displaying the measured pressure on the dial.

With Class 0.4 accuracy, a stainless steel construction, and optional 100 mm or 150 mm dial sizes, the YB Series is suitable for applications requiring more precise pressure readings than general-purpose industrial pressure gauges.

Different pressure units, process connections, and mounting configurations are available according to the selected model and application requirements.

Typical Applications

Laboratory Pressure Testing

For pressure indication in laboratory test systems where precise mechanical readings are required.

Pressure Gauge Inspection

For pressure comparison and inspection tasks involving compatible pressure test equipment. Calibration suitability depends on the reference standard and testing procedure.

Hydraulic System Testing

For monitoring pressure during hydraulic equipment testing and maintenance, within the specified pressure range.

Pneumatic System Testing

For pressure indication in pneumatic test benches and equipment inspection systems.

Pump and Compressor Testing

For monitoring pressure during equipment performance testing and maintenance.

Industrial Quality Inspection

For pressure measurement and inspection processes in manufacturing and industrial maintenance facilities.
