Installation Manual
eSENSE Outdoor™
CO2transmitter with heater and inline
thermostat mounted in IP65 housing
eSENSE Outdoor Product # SE-0036

2
The eSENSE Outdoor PCB is housed in an IP65 housing with breathers to support
the flow of outdoor air. If for some reason the PCB must be removed care must be
taken to protect from electrostatic discharge! Normally, removing the PCB is NOT
required.
The eSENSE Outdoor includes an in-line thermostat in order that heating of the
housing only takes place when the outdoor temperature warrants the use of the
energy to maintain an above freezing temperature in the housing. Maintaining an
above freezing temperature prevents the accumulation of ice crystals inside the
Optical Bench Assembly, which could cause inaccurate CO2 measurements.
Electrical connections
The power supply must be connected to + andis considered as system
ground. If the analogue output is connected to a controller the same ground
reference has to be used for the eSENSE unit and for the control system! Unless
different transformers are used, special precautions need to be taken.
PLEASE NOTE! The eSENSE signal ground is not galvanically separated
from the eSENSE power supply!
Please NOTE!
The same ground reference has to be used for the eSENSE unit and for the
control system!
The eSENSE Outdoor can be mounted to a wall or other supporting structure using
the four corner mounting holes or the top and bottom mounting holes.
Connection of Power to Terminal 1 and Ground to Terminal 2 must maintain the 2
connections associated with the heater. The eSENSE Outdoor is shipped with the
heater connections already in place for ease of installation.

Note 3: Accuracy is defined after zero calibration or after minimum 23 days of continuous operation. The tolerance of the
span gas (2% unless otherwise requested) and test gas adds to the total uncertainty.
Note 4: For reference see TN-025 "on pressure sensitivity".
Note 5: The specifications are valid for the output load connected to Ground G0.
