Mounting guidelines

When mounting and installing a Differential Pressure Sensor it's recommend to consider the following guidelines.
Sensor mounting location guidelines
• Sensor is commonly mounted in the Reference Space.
• Sensor mounting location is required to in close proximity to wall plate to allow tubing to be connected to the sensor
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.
• Easily accessible for maintenance and clear from obstructions. Avoid a location that would interfere with the use of
the monitored unit or area.
• Wireless Network use
It's recommended that the device is in a clear line of sight to a wireless access point. If the location is NOT in a clear
line of sight to a wireless access point, its LCD screen must be above the unit it's being mounted to.
Wireless signal strength of -60db or better at the mounting location. It's recommended to measure the strength with
a Wi-Fi analyzer app on a mobile phone.
• PoE/Ethernet use
An open, active network port in close proximity to the mounting location.
• AC power
Outlet within 5 ft. (1.5 m) from its mounting location. Devices using AC or PoE power can also use battery power as a
backup power source in the event of a power loss. During battery backup, the device operates on battery power and
continues to log and transmit readings until the primary power source is restored.
CAUTION
The device is shock and vibration resistant; however, be careful not to drop or install the device in a
location where it could be exposed to excessive vibration.
