A/LP SeriesLow Differential

Pressure Transmitter

Wiring Diagrams available at www.workaci.com/instructions.htm

The A/LP Series transmitters are a low cost alternative to the A/DP series pressure transmitters. The A/LP Series is a 4-20 mA transmitter with uni-directional spans.

These pressure transmitters incorporate a durable piezoresistive, silicon micro-machined sensing element to enable very low-pressure measurements. Integrated temperature compensation with offset and span calibration extends the performance of these devices to provide excellent long term reliability.

The transmitters must be powered by a +24 to 36 VDC or 24VAC supply. The electronics provide a two-wire, linear 4-20 mA current loop. The uni-directional spans range from 0-1” to 0-5” of Water Column. The A/LP is now available with a Cord Grip and ½” NPT Knockout when ordering the “Euro” Enclosure option.

All A/LP Series Transmitters come with a limited 2-year warranty. Please contact ACI for more information regarding this product.
