The data plate shows important information about the Sentinel TEG and can be used as a quick
reference point when performing service or contacting GPT. When contacting GPT, indicate both the
complete Model Number and Serial Number of your Sentinel TEG. The Sentinel TEG data plate is
located on the outside of the instrumentation enclosure door.
Information shown on the data plate:
Model Number The Sentinel TEG’s model number.
The Sentinel TEG comes in two different models as follows:

SENTINEL10-12 — provides 8 Watts at 12V DC BOCL

SENTINEL10-24 — provides 8 Watts at 24V DC BOCL
Serial Number A unique number assigned to the TEG unit by GPT for traceability.
Service Request No. Number assigned by GPT Customer Service when a Sentinel unit is sent
in to GPT for service.
Fuel Type The Sentinel Thermoelectric Generator is designed for Natural Gas fuel
only.
Gross Heating Value Amount of heat produced by a unit quantity of fuel.
Input Rating Maximum permitted energy rate to the Sentinel TEG.
Inlet Pressure Minimum and maximum levels of inlet fuel pressure permitted.
Design Altitude Maximum permitted altitude that the Sentinel TEG should be operated
at.
Preheating Element Specifies the electrical parameters of the preheating element.
Internal Impedance of
Generator
Internal impedance of the thermopile elements used in the
Thermoelectric Generator.
System Output Nominal voltage and power output of the TEG.
Factory Settings:
Open Circuit Voltage at
Ambient Temperature
Open Circuit Voltage and temperature recorded during the factory
acceptance test. This is the maximum voltage that can be expected from
the TEG under similar conditions.
Altitude Altitude of the factory where the factory acceptance test was
performed.
Manifold Fuel Pressure Manifold fuel pressure recorded during factory acceptance test.
