ACI/600 Differential or Gage Pressure Transmitters

Differential or Gage Pressure Transmitters
ACI/600 Series

Product Description:
The ACI/600D series is a line of differential or gage pressure transmitters. The transmitters are capable of sensing full scale ranges down to 1.0" of water column. The transmitter electronics provides a two-wire, linear 4 to 20 mA signal or an optional voltage output. Accuracy is +/-1% of full scale over the compensated temperature range. The transmitter can be powered from a 12 to24 VDC or 24 VAC supply. Commonly specified spans are 0 to 1", 0 to 2", 0 to 3", and 0 to 5".

ACI pressure transmitters can be used in many different applications. They can 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. This pressure transmitter uses a durable and proven technology to provide lengthy and stable performance.

All ACI/600D low differential pressure transmitters come factory calibrated with a 2 year warranty.
