4.4 – PROCESS CONNECTIONS (con't)
To the selected process connections, customer should install appropriate fitting required to connect process signal
tubing/piping from process sensor.
Note: When installing process connections, use appropriate thread lubricant/sealant.
When connecting the VELTRON DPT to an airflow measuring device, connections must be completed as follows:
– High Port on VELTRON DPT connects to Total Pressure from airflow measuring device.
– Low Port on VELTRON DPT connects to Static Pressure from airflow measuring devices.
When connecting VELTRON DPT for positive room pressurization, connections must be completed as follows:
– High Port on VELTRON DPT connects to sensor from monitored room.
– Low Port on VELTRON DPT connects to reference sensor.
When connecting VELTRON DPT for negative room pressurization, connections must be completed as follows:
– High Port on VELTRON DPT connects to reference sensor.
– Low Port on VELTRON DPT connects to sensor from monitored room.
Although any size of tube/pipe can be used, the response time of the VELTRON DPT to process change increases with
increasing tube/pipe size or increasing tube/pipe length.
SECTION 4 – INSTALLATION
CAUTION
It is extremely important that no pressure be present in signal tubing at the time
of installation, and the orientation of high and low pressure signal lines
is maintained between the source and the VELTRON DPT.
