Application

    Differential pressure gauge is widely used to measure fan and blower pressures, filter resistance, air velocity, furnace pressure, orifice differential pressure, air bubbles and liquid water or hydraulic pressure amplifier, while the process is also used for combustion air gas ratio control and automatic valve control, and health care facilities in blood pressure and respiratory pressure monitoring.

   It is widely used in medical, microelectronics, aerospace, environmental engineering, biological engineering, pharmaceuticals, building intelligent, HVAC, food and beverage, precision electronic processing.

Technique Data

• Environment temperature:-70 ~ 60°C
• Rated pressure:-68 ~ 103KPa
• Overvoltage: about 172KPa overvoltage when the rubber stopper has been rushed to open.
• Process connection: high and low pressure holes are 1/8 " threaded spinal canal, two groups(each side and back)
• Shell material:Die cast aluminum, aluminum and chrome body parts after 168 hours salt bath test, the final coating of dark gray exterior.
• Precision:Under 21 °C is ± 2% FS (- 125PA;250pa type  is 2%, -60 pa type is 2%)
