1/4” push-on. To achieve the shortest response times, larger diameter tubing can be used on long tubing runs. All ACI/DP units can handle a maximum pressure of 5 times the sensor range on the High side and 3 times the sensor range on the Low side.

SELECTING ANOTHER SPAN Each uni-directional ACI/DP unit has the capability of being switched to three spans other than the span ordered. The bi-directional units have only two span capabilities. The switch to other spans is achieved by changing the position of jumpers found inside the enclosure. After opening the enclosure, there will be two sets of jumpers. One is a double row of pins (J4) with four positions numbered 1 through 4.
