Our pressure gauge series combines the intuitive readability of mechanical indication with the accuracy of digital display. Mechanical gauges use vibration-resistant, liquid-filled structures to suppress pointer flutter caused by pressure pulsation, while digital pressure gauges provide higher-precision real-time data feedback and backlit display. With strong environmental adaptability, they serve as the first on-site pressure inspection window for pipelines and tanks in chemical plants.
The SX-PGBCC Series digital display pressure gauge uses piezoresistive sensing technology to provide accurate, real-time pressure measurement across a wide range from vacuum to high pressure. It features a 4-digit LCD display with a pressure percentage bar graph, unit switching, one-touch zero reset, backlight, and low-battery indication. Battery-powered and 24 V DC versions are available, with optional 4–20 mA or RS-485 / Modbus RTU output. Its 304 stainless-steel housing and wetted parts make it suitable for gases, liquids, oils, hydraulic systems, industrial piping, pressure vessels, portable instruments, and automation equipment.
