ELECTRICAL INSTALLATION

Two-wire units (option 0)
Four-wire units (options 1 to 4)
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.
• Do not damage the cable, as this could provide a path for moisture and vapour into the
sensor.
• Do not open the sensor housing. This will damage the sensor and invalidate the warranty.
