IM 12B6K3-01E-E
1. INTRODUCTION
1.1 Description
The retractable fitting with ball valve allows
a safe insertion and retraction of a sensor
while the process is under pressure. It
can be mounted in a variety of positions.
The insertion depth can be selected on
site. An insertion stop is provided to set
the position of the sensor in the process.
The mechanism for releasing the probe
is designed to operate only when the ball
valve is closed, thus ensuring an effective
safety precaution and avoiding production
loss. The sensor can be replaced or
calibrated easily.
1.2 Features
• One model for pH, conductivity
and inductive conductivity sensors
• Integrated protection cage
• Build-in scraper to avoid contamination
of the fitting
• Usable for wide range of sensors
• A safe “through the valve” insertion
and retraction design
• Simplified installation by optional
ball valves with flanged or tapered
connections
• Optional flush port for keeping moist,
cleaning and calibration
• Available in Stainless Steel and with
Titanium shaft cage and adapters for
more harsh applications
