Low Differential Pressure Transmitters

Product Data

ACI/DP Series

The ACI/DP series is a line of low differential pressure transmitters that are capable of sensing full scale ranges down to 0.25” of water column.  Each ACI pressure transmitter utilizes a high quality ceramic capacitive sensor to provide long term stability and performance.  Variable capacitance sensors have a good signal to noise ratio and are not plagued by temperature drift.

The transmitter electronics provides either a two-wire, linear 4 to 20 mA or a three-wire, 0 to 5 or 0 to 10 VDC output signal.  Accuracy is +/- 1% of full scale over the compensated temperature range.  The transmitter may be powered by a regulated, +15-36 VDC or 24 VAC supply, and is polarity sensitive.  In addition to the requested span each transmitter is capable of being field adjusted to three additional spans, by resetting the internal jumpers. A slight zero

offset may be needed.  This feature provides greater flexibility in the field.  Commonly available spans are 0 to 0.25”, -0.5 to 0.5”, 0 to 1”, 0 to 2.0”, and 0 to 5”.

 ACI pressure transmitters may be used in many different applications including:

            ·         Static Pressure Control in Rooms
      ·         Leak Detection
      ·         Monitoring Filter Blockage
      ·         Pneumatic Controls
      ·         Variable Air Volume Systems (VAV’s)

When used in combination with an ACI/PT, ACI/SPT, or ACI/VPT style pitot tubes, flow can be measured and controlled in ducts.  All ACI/DP low differential pressure transmitters come factory calibrated with a 2 year warranty.
