Differential Pressure Transmitters


Low Differential Pressure Transmitters

ACI/LP Series

Product Description

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

These pressure transmitters incorporate a piezoresistive, silicon micro machined sensing element to enable very low pressure measurements.  Integrated temperature compensation with offset and span calibration extends performance of these devices without a sacrifice in accuracy.

The transmitters are powered by a 24 to 36 VDC or 24 VAC supply.  The electronics provide a two-wire, linear 4-20mA current loop or an optional voltage output.  The uni-directional


spans range from 0-1 to 0-10 WC.  Factory units are calibrated with a 4-20mA output as standard.  If voltage output units are required, they must be ordered as such from the factory.

ACI pressure transmitters may be used in many different applications.  They may be used in static pressure applications such as pressure control in rooms or leak detection.  Another application is monitoring filter blockage.  In combination with a pitot tube or orifice plate, flow can be measured and controlled in ducts.  The pressure transmitter uses a durable and proven technology to provide lengthy and stable performance.

All ACI/LP Series transmitters have a limited 2 year warranty.
