Installation Guide Pressure TM Product Identification Specifications Product Overview The PW2 Series sensor is designed to accept high differential pressure. Install the sensor on a duct or pipe across a pump, filter, heat exchanger, compressor, or other non-corrosive wet media. The dual sensor design eliminates the need for a bypass valve, and the bi-directional capability reduces installation errors. A pushbutton allows easy zero adjustment. PW2 Series Wet Media Differential Pressure Transducer Local Display L = LCD Display X = No Display NIST N = NIST X = None Options S = Standard BP = With mounted bypass assembly Operational Range* 03 = 0 to 50 psig 04 = 0 to 100 psig 05 = 0 to 250 psig PW2 * IMPORTANT! Select operational range according to maximum gauge pressure, NOT differential pressure. Example: High gauge pressure=90 psig, select 100 psig model (04).

TM PW2 Series Installation Guide Operation JumperNotes Port Swap/NormReverses polarity of the pressure ports (i.e. makes the LO port operate as the HI port and vice versa); used when the sensor is incorrectly plumbed. Bi-Dr/NormalNormal: 0 to F.S. pressure Bidirectional: -F.S. pressure to +F.S. pressure; output reads 1/2 when pressure is zero. Slow Avg/Fast NormSlow mode provides 5-second averaging for surge damping. Analog Rev/NormNormal: Output increases as pressure increases; Reverse: Output is maximum when pressure differential is zero and decreases as pressure increases. Bar/PSISelect output units. Auto-Zero: Press and hold the Zero button for two seconds or provide contact closure on the auxiliary ‘Remote Zero’ terminal to reset the output to zero pressure. To protect the device from accidental zeroing, this feature is only enabled when the detected pressure is within 5% of factory calibration. Installation Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty. 1.
