ELECTRICAL INSTALLATION
PyroEpsilon Sensor
Do not connect power
OPERATION
Once the sensor is in position and the appropriate power, air, water, and cable connections
are secure, the system is ready for continuous operation by completing the following simple
steps:
1 Turn on the power supply
2 Turn on the meter, chart recorder or controller
3 Read / monitor the temperature
IMPORTANT
Be aware of the following when using the sensor:
• If the sensor is exposed to significant changes in ambient temperature (hot to cold,
or cold to hot), allow 20 minutes for the temperature to stabilise before taking or
recording measurements.
• Do not operate the sensor near large electromagnetic fields (e.g. around arc welders
or induction heaters).
• Electromagnetic interference can cause measurement errors.
• Wires must be connected only to the appropriate terminals.
