FOB Price : Get Price

Differential Pressure Instrument is targeted at precise differential pressure measurements in air conditioning and ventilation technology. It is excellent for use in measuring the pressure drop on filters and in checking fans and extractors. Differential Pressure instrument is also suitable for Pitot tube measurements in ventilation ducts or in process air (in the 5 to 100 m/s range).

Differential Pressure measuring instrument has an integrated temperature-compensated differential pressure sensor which measures with an accuracy of 0.1 % of f.v. Differential Pressure Instrument can attach up to 2 further optional probes to the measuring instrument.

following probes:

  • Differential pressure probes
  • Absolute pressure probes
  • Temperature probes (e.g. surface probes or immersion and penetration probes
  • Relative pressure probes

Differential Pressure Indicators are high accuracy instruments with integrated display & 4-20mA Analog Output. The differential pressure indicator has a 4 digit red L.E.D. Display of 0.5” Height with 0.1 mm.W.C. or 1 Pascals resolution. Industry standard 4-20mA Analog Output is available as standard output. Optional RS485 Modbus Output is also available for connecting to BMS/SCADA. Ranges available are from -10.0 to 10.0 mm. W.C./ 0.0 to 10.0 , 20.0, 50.0, 100.0, 25.0, 500.0, 1000, 2500, 5000 & 10,000 mm.W.C. The differential pressure indicator is provided with selectable units of mm.W.C. & Pascals selectable from front "UNIT" key. Any other standard metric unit can be accommodated including cm. W.C., In. W.C., In. Hg., mm. Hg. Integrated buzzer alarm for process violation is a standard feature with option of Enable/Disable Alarm with alarm delay time programmable. Customized measuring ranges can be provided as per requirement.

  • Factory calibration laboratories
  • Calibration service companies and service industry
  • Research and development laboratories

Special Features:
  • Measuring ranges from 0 ... 25 mbar to 0 ... 700 bar (up to
  • 2 separate internal precision sensors possible)

Differential Pressure Indicators are extremely useful in pharmaceutical Laminar Air Flow Cabinets, clean rooms, Air Handling Units, Hepa Filters, Filters, Bag Filters, pharma machinery, Biosafety Cabinets, Laminar Air Flow Units, HVAC etc. Differential pressure indicators come in Aluminium LM-6 Body with Integrated High Speed Sensor with an accuracy of /-0.5%F.S. & 40 mm. depth & fits into industry standard Mounting Holes like the Analog Magnahelic Gauges. Customization is possible for quantity orders.
