A sensor maintenance kit
The maintenance kit includes the material needed to service and maintain the sensor.
Storage information
During a short shutdown period (such as weekends), the sensor may stay in place with the
instrument turned on, and purge gas supplied. If the inactive period is likely to last longer, remove the
sensor, wipe it dry and store it properly, using the plastic storage cap supplied.
C A U T I O N
We recommend you use the ORBISPHERE 32605 Purge safety backup unit to ensure that the purge gas supply
to the sensor will not get interrupted in case of a mains power outage. See
on page 10.
Instructions for sensor storage
• If the sensor’s head shows deposits, rinse it under tap water.
• Wipe the sensor head dry.
• Put a small silica desiccant bag inside the storage cap.
• Put the storage cap in place.
• Store the sensor in a safe dry place.
• The storage place must be at a stable room temperature.
C A U T I O N
Pay attention to rapid temperature change situations, such as air conditioning being turned on and off daily, that
may create condensation inside the sensor’s cell and damage the electronics inside.
Installation
Pre-installation
1.
2.
1.
The sensor head is protected by a screw-on black plastic storage cap. This cap should be
removed.
2.
Once the storage cap has been removed, an orange sticker will be visible informing you not to
remove the protection cap. This is because the sensor has already been checked and calibrated
prior to shipping, and no sensor maintenance or membrane change is required prior to first use.
However, this label must be removed.
3.
Attach the two small identification clips (stamped with the letter “T”) to each end of the sensor
cable so they are clearly visible. These clips indicate this is a TC sensor, so when connecting to a
multi-channel analyzer, care must be taken to connect it to the TC measurement board.
