Applications DP differential pressure transmitter applies new CDM technology, can precisely monitor very low range differential pressure with multiple functions. It can compensate temperature effect, and is not sensitive to media and dust or moisture, and does not have any pressure drift, so it is very reliable. The pressure vibration can be filtered by the damping function. The output is steady under very low range pressure. It could even be installed in the outside air environment between -20 70°C. It is applicable to: clean room, isolated room, ventilation system, energy management system, leak testing,air velocity measurement, medical care and test instrument, furnace pressure test, etc. Features Magnetic sensing technology Non-sensitive to media, compared to transmitters using a piezoresistive silicon or capacitance sensor DP range Minimum to 25Pa and accuracy is 1% Three selectable ranges for each model Range, full-scale output and zero could be easily selected, set and calibrated by jumper or button in field, do not need extra pump equipment Available with unidirectional and bidirectional ranges, and air velocity, applicable for positive, negative or differential pressure Selectable double lines four bits LCD Display Excellent stability High protection housing IP65 Models Code Specifications DP Diff.
