PW Series

Wet Media Diﬀerential Pressure Transducer

Product Overview

The PW Series pressure transducer measures the dierential pressure across pumps, lters, heat exchangers, and other non-corrosive wet media. Several operational pressure ranges are available, and the analog output is user selectable (4-20 mA, 0-5 V, or 0-10 V). PW Series devices are warranted to meet accuracy specications for a period of ve years.

Installation

Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty.

1. Find a suitable mounting position near the location to be measured. Mount the PW housing using the self-tapping screws provided.

2. Remove the lid from the housing to reveal the board. Wire the PW terminals to the power source and to the digital control system as shown. Congure the jumpers for desired operating parameters. Replace the cover.

Jumper Options Notes

JP1 Voltage (V) or Current (mA)

JP2 0-10V or 0-5V output span Use only if JP1 is set to V mode.

JP3 Slow or Fast Slow mode provides 5 second averaging for

surge damping.

JP6 Normal or Bidirectional Normal: 0 to F.S. pressure

Bidirectional: -F.S. pressure to +F.S. pressure;

output reads 1/2 when pressure is zero.

JP7 Normal or Port Swap Reverses 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.

JP8 Normal or Analog Reverse Normal: output increases as pressure increases;

Reverse: output is maximum when pressure

dierential is zero and decreases as pressure increases.

4. Connect the other ends of the tubing to a pipe or duct, across the pump, lter, or other pressure dierential.

Notes

During operation, the LCD shows two pressure values. The value adjacent to the PSID label shows the dierential pressure, while the value adjacent to the PSIG label shows the high port gauge pressure. The gauge pressure value is read from the high port if JP7 is in the Normal position. If this jumper is in the Port Swap position, the PSIG value is read from the low por t, and the value is usually a negative number.

This product uses a half-wave rectier power supply. If the installer is using a transformer to power the device, do not use the same transformer to power other devices utilizing non-isolated full-wave power supplies.

Optional: Connect the Zero terminals to the digital output (contact closure) of the control system. The Zero input is for dry-contact only. Do not apply voltage to the Zero terminals.

To use the auto zero function, press and hold the Zero button for 2 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.
