Function Description
Mounting
• Possible mounting angle: 15° above horizontal.
• Mounting angle 360° (i.e. even upside down) for
special sensors only containing thickened electrolytes
which thus cannot flow.
The pneumatically operated sensor lock-gate allows calibrating or adjusting the measuring system and clean-
ing the sensor in the running process. For that purpose, the sensor can be moved between two positions:
PROCESS position: The sensor is located in the process medium.
SERVICE position: The sensor is located in the calibration chamber.
In SERVICE position the measuring system can be calibrated or adjusted or the sensor can be cleaned.
Using compressed air, a control unit such as the Unical 9000 moves the sensor between SERVICE position
and PROCESS position and leads different calibration and/or cleaning liquids to the sensor located in the
calibration chamber.
These liquids leave the calibration chamber through an outlet hose, i.e. they are displaced from the
calibration chamber by following liquids or by compressed air.
To replace the sensor, you must move the sensor lock-gate into SERVICE position.
With the Unical 9000 probe controller, all media, control air, and the check-back cable for position indication
of the probe are connected to the sensor lock-gate through a compact connector (multiplug).
Since the pneumatic drive unit and the process unit with the ceramic sensor lock-gate are separate modules,
the drive unit can be removed and replaced under process conditions.
