Sensor mounting
W A R N I N G
Personal injury hazard. Always consider the temperature and pressure rating of the mounting hardware that is
used to install the sensor. The hardware material usually limits the temperature and pressure rating of the system.
835x series sensor
The sensors can be installed in any position.
• Insertion mounting: screw-in or flange fitting
• Immersion mounting: immersion shafts (0.5, 1, or 1.5 meters) with fixed, adjustable or clip-type
flange.
The sensors are fitted with 10 metres of cable as standard.
For longer cable lengths (up to 25 meters) use a junction box (08350=A=8500) and the 2654 cable
(358048,00000).
For cable lengths greater than 25 meters, use a pre-amplifier unit (08350=A=8000) and the
2666 cable (370=506=025). In this case it will not be possible to monitor the impedance.
Using the pre-amplifier unit
With this scenario it is impossible to connect the solution ground.
