Sensor Dismount Guard
(only for sensors with solid electrolyte)
In conjunction with the Unical or Uniclean electro-pneumatic
controllers and the Protos measuring system, the Ceramat is
fitted with a sensor dismount guard. This serves to prevent the
immersion of the sensor lock-gate without sensor (a message
is triggered in the Protos). If the sensor is absent or incorrectly
mounted, compressed air noticeably and audibly escapes from
below the drive's coupling nut.
The outflowing compressed air is detected by a flow switch
in the Unical and signals the missing or incorrectly mounted
sensor to the Protos.
The sensor dismount guard only works with a correctly
installed O-ring (B) and slip ring (A) on the sensor. If these
elements are not present, the “Sensor dismounted” message is
shown in the Protos display.
Before installing a new sensor, check whether there are any
sealing elements at the bottom of the sensor holder from
previous installations which have not been removed!

Installing/Removing a Sensor
Note
When using a PEEK scraper ring on the sensor socket of the Ceramat, or when retrofitting a Ceramat with
sensor socket including scraper ring as accessory ZU 0705, ZU 0706, or ZU 0707 (see Accessories page 35),
the proper functioning of the sensor dismount guard in combination with the Unical/Uniclean cannot be
guaranteed. Buildup of contaminations can result in high stripping forces which impair the functioning of the
sensor dismount guard.
NOTICE
Therefore, the operator of the Ceramat must always make sure that a sensor is installed before moving the
probe to PROCESS position (measuring).
pH Sensors
Be sure to follow the assembly instructions step by step.
Preparations:
• Check whether the sensor is damaged (glass broken?).
Never install a damaged sensor.
• Check whether slide washer or O-ring on the sensor are damaged and replace if required.
• Remove watering cap from the sensor tip and rinse sensor with water.
