Explanation of the Main Features of Digital Differential Pressure Gauge!

Introduction of digital differential pressure gauge


The digital differential pressure gauge uses a micro differential pressure sensor as the pressure sensing element, and is equipped with ultra-low power digital conditioning circuit, which makes it have high accuracy and good long-term stability.


It has the same installation method as mechanical differential pressure gauges, which is convenient for engineering personnel to install and debug on site. It can be used for measuring and controlling high-precision differential pressure in clean rooms, operating rooms, dust-free rooms, ventilation systems, and fan testing, etc.


The digital differential pressure gauge has no moving parts, anti-vibration, high precision, zero position calibration, unit switching, relay setting, and other characteristics. There are multiple range and unit options available. It can be widely used to measure the pressure of fans and blowers, filter resistance, air velocity, pressure drop caused by orifice plates, liquid level in bubbler systems, and pressure of boosters or hydraulic systems. It can also be used to monitor blood and respiratory pressures in medical equipment.


Characteristics of digital differential pressure gauge:


  • Displays 11 different units, freely selectable;

  • High accuracy, good stability, small size, light weight, and rigid anti-seismic performance;

  • Good one-way overload protection, no mechanical movable parts, and less maintenance work;

  • Unified structure for the entire series, strong interchangeability of components, and selectable diaphragm material for contact medium;

  • Collection speed (0.25-10) seconds/time, freely configurable;

  • The power supply battery is designed to be replaceable at any time;

  • The keypad is designed with magnetic pen induction, which is free from interference and not easily damaged;

  • Wide-screen five-digit LCD display, very eye-catching;

  • Displays the pressure percentage bar chart, which is intuitive and easy to understand;

  • Auto-temperature compensation technology reduces errors in harsh environments;

  • Zero-point automatic stabilization technology increases instrument stability;

  • Explosion-proof structure, suitable for all-weather use.


The display of the digital differential pressure gauge is a digital LCD display, and the number of digits displayed dynamically is 5, which can display pressure, temperature, liquid level, etc., so the corresponding units of the measured objects can also be displayed above.


In addition to clear digital display, the design of the digital pressure gauge also includes a special indicator bar, which is indicated by a light column on the instrument. The height of the light column varies depending on the different pressures or temperatures measured, so it can more intuitively reflect the percentage of the measured object.
