Digital Pressure Gauge

What Communication and Output Options Are Available for Digital Pressure Gauges?

• Local LCD visual display output: Built-in high-resolution LCD screen serves as direct local output, showing real pressure values, percentage progress bars and peak readings. Five switchable engineering units are supported for on-site quick reading without extra signal receiving equipment.

• Built-in manual parameter output function: Zero offset correction and upper/lower limit setting act as internal adjustment output modes. Operators calibrate measurement deviation directly via front buttons to adjust displayed data, realizing local parameter output without external control signals.

• Peak value data storage output: The gauge automatically records and stores maximum pressure peaks during operation, which can be called up with one key. This built-in data recording output provides historical pressure peak reference for on-site equipment fault analysis.

• Standalone battery-powered passive output: It adopts 9V battery power supply with no wired analog/digital communication lines. All display and data functions are self-contained passive output, ideal for portable field measurement without PLC or wired transmission wiring.

What Makes Digital Pressure Gauges More Accurate Than Traditional Mechanical Gauges?

• Advanced solid-state sensing core: Digital piezoresistive sensors avoid elastic fatigue of Bourdon tubes in mechanical gauges, sustaining stable precision under repeated pressure shocks.

• No visual parallax error: Clear digital numerical readings replace pointer scales, eliminating subjective reading deviations caused by different viewing angles of mechanical dials.

• Convenient on-site zero calibration: One-touch zero reset corrects drift from vibration and temperature, while mechanical gauges lack simple field calibration solutions.

• Better long-term stability: Digital sensors feature tiny annual drift, unlike elastic tubes that deform gradually and grow inaccurate with long service time.

• Peak pressure memory function: It automatically records max pressure values, whereas mechanical pointers fail to retain transient extreme pressure data.
