Air Velocity Probes & SensorsAir velocity measurement isan important factor in thecontrol of ventilation systemsto ensure that recommendedflow rates are achieved.AV-EP multi-point sensorscan be used to ensure thatoptimum sensing is achieved.Use AV-MPS multi-point sensors in pairsdepending on size of duct:600-700mm (23.62-27.56”) · AV-MPS700700-800mm (27.56-31.50”) · AV-MPS800750-1000mm (31.50-39.37”) · AV-MPS10001000-1250mm (39.37-49.21”) · AV-MPS12501250-1500mm (49.21-59.06”) · AV-MPS15001500-1750mm (59.06-68.90”) · AV-MPS17501750-2000mm (68.90-78.74”) · AV-MPS2000AV-DSPSingle-point Air Velocity SensorThe AV-DSP is a single-point, multi-rangeAir Velocity Transmitter with user selectable0-10Vdc or 4-20mA outputs and four userselectable measurement ranges. The unit hasa built-in self-test feature and the user canmanually override the output to 0%, 50% or100% of output range to aid commissioning.FEATURES■■User selectable 0-10Vdc or 4-20mA outputs■■Built-in self-test feature■■Built-in manual override facility for 0%, 50% or 100% of output range■■Durability and resistance to chemical reagentsPart codeAV-DSPDPAData sheet: AV-DSP.pdfDescriptionAir Velocity SensorAccessoryDuct probe adjustment flangeSPECIFICATIONSelectable ranges:Accuracy:Output:Supply (current output):Supply (voltage output):0 to 4 m/s, 0 to 8 m/s, 0 to 16 m/s, 0 to 32 m/s,0 to 787 ft/min, 0 to 1575 ft/min, 0 to 3150 ft/min,0 to 6299 ft/min±3% of ranges4-20mA, 100Ω loop resistance min.0-10Vdc into 4.7kΩ min.20 to 35Vdc for 500Ω loop resistance12 to 30Vdc for 100Ω loop resistance17 to 34Vdc14 to 26Vac supply into 4.7kΩ min.50mA–10 to +50°C (14 to 122°F)Max. current:Ambient temp. range:Housing: Material Flame retardant ABSDimensions 55 x 90mm dia.
