A Differential Pressure Sensor mounting kit is used for through-the-wall installation in combination with a Differential Pressure Sensor. The kit allows assembly through a solid or hollow wall.
Where the sensor is mounted, either in the Controlled or Reference Space, determines how the sensor and mounting kit is installed. Commonly, a sensor is mounted in the Reference Space.
Allows staff to view readings when outside of the Controlled Space.
Tube is attached to the High (H) pressure port and the Low (L) pressure port is open to the Reference Space.

When mounting and installing a Differential Pressure Sensor it's recommend to consider the following guidelines.
Sensor must be in close proximity to the wall plate to allow tubing connection to the sensor's pressure port.
Sensor must be mounted vertically; pressure ports pointing down. If the pressure ports point upward, condensation can collect inside the sensor causing damage to the device.
It's recommended to only use the supplied flexible silicone tube.
Tubing must be free of crimps or obstructions that may inhibit airflow to the sensor pressure port.
Arrange tubing to minimize stress on the connection to the sensor's pressure port.
Tubing must be kept clean to avoid material falling into the sensor pressure port, as contamination could damage the port sensor.
Tubing can be cut to length to support application use.
If tubing is longer than the supplied 6 ft. (1.82 m) tubing, reading accuracy may be affected due to reduced air flow within the tubing. A general rule is that for each additional 2 ft. (.61 m) of tubing, a 1% of error is introduced into the differential pressure reading. For applications that are only interested in a positive or negative pressure indication, the overall accuracy of the reading may not be an issue. For an application use that requires a tubing length that exceeds 6 ft. (1.82 m), contact your Primex Support to calculate the extended tubing error rate.
Remove the device cover; simultaneously press the two tabs located on the top side of the device (A).
Insert the 3.0v Primex Lithium/Iron Disulfide Battery Pack or two 1.5v Lithium AA batteries. Follow the symbols showing the correct way to position the positive (+) and negative (-) ends of the battery pack.
Located to the lower-right of the battery compartment, set the battery on/off switch to the Up (On) position (B).
-
Replace the device cover.
Drill a hole through each side of the wall that is large enough to pass through the tubing. Wall cut out should not exceed the dimension of the supplied wall plate.
-
Complete the following steps based on where the sensor will be mounted. Refer to the above Install Illustrations.
-
Mount sensor using the key-hole slot on backside of unit. Optionally, mount the sensor to a surface using the supplied 3M™ Dual Lock Fastener Tape (2" x 1" strips). It's recommended to place the strip(s) horizontally.
Determine the mounting location by referencing the key-hole slot located on the back of the device. Pre-drill mounting hole into the wall surface and insert wall anchor.
Insert a #6 drywall screw into the wall anchor, leaving approximately 3/8 in. (0.95 cm) of the screw head exposed for hanging.
Attach device by sliding the key-hole slot onto the mounting screw. Ensure the device is properly secured and level.
-
Attach tubing to appropriate port located on the bottom side of the sensor. Refer to the Install Illustrations.
Where the sensor is mounted determines the port the tubing is attached to.
Sensor located in Reference Space: push tubing onto the sensor H (High) port.
Sensor located in Controlled Space: push tubing onto the sensor L (Low) port.
Tubing can be cut to length as required. Ensure the tubing between the wall is straight with no kinks, excess tube, or obstructions that would prevent proper airflow.
Dress and secure the tubing as needed. Arrange the tubing to minimize stress on the connections and ensure there are no kinks in the tubing.
Apply primary power to sensor; AC or PoE.
Secure wall plate to surface.
Snap the sensor's removable port cover into place.
Verify Signal OK is displayed on the LCD screen, which indicates it successfully checked-in. When power was applied, the sensor initiated a check-in to OneVue.
-
If Signal OK is not displayed, initiate a manual check-in. From the front of the sensor, press and quickly release the check-in button
(up arrow). The sensor emits a series of audio beeps indicating its connection sequence. During an active check-in connection, additional pressing of the check-in button is ignored.
Verify the following settings are configured to meet the requirements of the condition being monitored.
-
Monitored Asset settings. Go to Monitoring > Monitored Assets.
Each Primex sensor is assigned to a Monitored Asset and its readings or monitored conditions generate the current and historical readings for the asset. In addition, sensor operating condition data is linked to its assigned Monitored Asset. When a sensor enters a Warning or Alarm state, its assigned Monitored Asset is also set to an Alarm or Warning state.
Sensor assigned to a Monitored Asset. Go to Devices > Sensors > select sensor > verify assigned Monitored Asset.
Monitored Asset assigned to sensor is added to an Alert Rule.
Monitored Asset assigned to sensor is added to a Report Profile.
Users responsible for the monitored condition are assigned to Monitored Asset's Business Unit.
-
Sensor settings (Go to Monitoring > Monitored Assets > select Monitored Asset > select sensor.
-
Normal Condition
The Normal Condition is the expected operating range or the condition of the Monitored Asset assigned to the sensor. The settings vary based on the type of sensor and the condition being monitored.
-
Alarm Delay
The Alarm Delay sets the amount of time OneVue delays setting the sensor and its assigned Monitored Asset to an Alarm state. When a sensor reading is not within its Normal Condition (an Out of Range status) and it remains Out of Range for the time period set in its Alarm Delay setting, the sensor and Monitored Asset are then set to an Alarm state with a status of Out of Range, Past Alarm Delay.
-
Audio Alert (sensor gateway setting)
Primex sensors are equipped with a reading alarm audio alert. The audio alert is activated when a reading is out of range and the time period it has been out of range has exceeded the time period set in its Alarm Delay. Be default, the audio alert is disabled.
-
Logging Interval (sensor gateway setting)
The Logging Interval is how frequent a sensor logs a reading and stores it into its internal memory. All logged readings are then sent to OneVue at the frequency set the sensor's Check-in Interval frequency.
-
Check-in Interval (sensor gateway setting)
The Check-in Interval is the frequency a sensor connects to the facility's network to send its logged readings to OneVue. Also during each check-in, pending setting updates are downloaded to the sensor.
-
Unresponsive Timeout (sensor gateway setting)
The Unresponsive Timeout is the maximum amount of time a Primex device can go without a check-in to OneVue. When this time limit is exceeded, the device is set to an Alarm state with an Unresponsive status.
