Low cost HVAC pressure sensor for clean-room air flow monitoring
The DPS low differential pressure transducer is an affordable sensor for measuring air-flow differential pressure in semiconductor processing clean-rooms, pharmaceutical research laboratories, building ventilation air ducts and factory air conditioning.
This economical HVAC pressure transmitter relies on wear-free inductive coupling technology to detect fractional movements in the sensing diaphragm. This sensing technology provides a highly stable and reliable method for sensing low pressures.
The DPS low differential pressure transmitter can be specified in ranges starting from as low as 10 pascals up to 1 bar which covers a wide range of applications whether you are controlling the differential pressure between two rooms, measuring the differential pressure in a ventilation duct, or detecting the condition of an air filter.
The DPS clean-room dp pressure sensor has a standard linearity of ±1% full scale with improved linearity options of ±0.5% FS & ±0.2% FS, the pressure hysteresis is better than ±0.1% full scale. Despite the low pressure range a good stability figure of ±0.5% FS per year is typically achieved.
The signal conditioning electronics of the DPS low range diff pressure transducer provide options for a 5 or 10 Volt DC output or a 4-20mA current output in either 3 wire or 2 wire configuration. The supply voltage can be 24Vdc, 230Vac or 115Vac mains providing flexibility for different air control systems.
If a local readout of pressure is required an LCD display can be integrated into the DPS differential air pressure sensors enclosure. An auto-zeroing feature for calibration purposes plus relay switch outputs for triggering an alarm are also available options along with the local display.
The DPS low differential pressure transmitter provides a solid mechanical design with excellent accuracy performance at a relatively low price point.
