Installation, assembly, start-up and maintenance may only be performed by appropriately trained personnel.
Check the nameplate for correct operating conditions.
For use in hazardous areas, special codes and regulations are applicable. Instruments must not be
connected to power supply before reading instructions described in the supplementary manual.
The responsibility as to the suitability, intended use and corrosion resistance of the used materials of this
device against the measured fluid rests solely with the operator.
SMARTPAT ORP sensors are factory calibrated. Nevertheless it is recommended to calibrate the sensor
before installing it into its final measuring location.
1. Connect the sensor to a device suitable for SMARTPAT ORP sensor calibration: OPTIBRIDGE / PC,
SMARTMAC, HART handheld, or your PLC.
2. Calibrate the sensor.
3. Install the sensor into its final measuring location.
1 Unpacking the sensor
Remove the protective cap from the sensor tip by gently twisting and pulling it .
• Lay the sensor on a soft ESD mat or soft paper tissue .
• Leave the protection cap on the VP connector, as long as the sensor is not connected to the cable.
2 Electrical connection
Danger:
All work on the
electrical connections may only be carried out with the power disconnected.
Take note of the voltage data on the nameplate.
Observe the national regulations for electrical installations.

4 Installation
Specific conditions of use to be observed for SMARTPAT ORP 8150 :
Operation with flammable media beyond the ranges of atmospheric conditions ( -20 °C ≤T ≤+ 60 °C and
0.8 bar ≤P ≤1.1 bar) is only permissible if these media do not form explosive medium/air-mixtures. The
operating company is responsible for the safe operation of the Redox-Sensor regarding temperatures and
pressures of the media used.
When the Redox-Sensor is operated with flammable media it shall be included in the recurring pressure test
of the system.
To avoid electrostatic charge, the metal enclosure shall be connected to the local equipotential bonding
system.
The digital Redox-Sensor, type SMARTPAT ORP 8150 must not be installed and operated in areas where
excessive charge generating processes can occur (e.g. due to friction or oncoming flow with particles).
The safety instructions given in the operating instructions manual shall be observed accordingly.
The installation must always comply with the following requirements:
• No external forces are affecting the sensor.
• The device is accessible for any necessary visual inspections and can be viewed from all sides.
• The nameplate is clearly visible.
Ensure that the pipeline is without pressure before installing or removing a sensor!
Never touch or scratch the platinum electrode of the sensor.
During installation you should fix a shut-off valve in front of and behind the instrument so that the sensor
can be taken out in case of check.
Warning:
The max. permissible temperature for the SMARTPAT electronics is 85°C.
Immersion installation:
Max. process temperature is 85 °C with a submersed sensor (or lower if glass electrode is rated lower),
e.g. with mounting assemblies SENSOFIT RET 5000 or IMM 1000.
Insertion installation:
The device must not be heated by radiated heat (e.g. exposure to the sun) to an electronics housing
surface temperature above the maximum permissible ambient temperature. If it is necessary to prevent
damage from heat sources, a heat protection (e.g. sun shade) has to be installed.
Mounting position of the sensor
The sensor tip must always have full contact with the measuring medium.
The mounting position of the sensor should not deviate more than 75° from vertical position (sensor tip pointing
downwards).
Measuring medium
Maximum deviation of 75° from vertical position
Installation steps
12 mm glass electrodes (SMARTPAT ORP 8150, 8510):
•Use a mounting assembly for insertion or immersion installation suitable to your purposes, e.g. SENSOFIT
INS 1310, RET 5000 or IMM 1000 etc. and follow all installation steps described in the appropriate user
manual of the mounting assembly.
•Ensure that the washer and the O-ring at the electrode are properly fitted, clean and undamaged.
•Take care when inserting the electrode into the mounting assembly.
•It is usually sufficient to tighten the PG 13.5 screw at the electrode by hand. If necessary, a wrench can be
used (carefully !). Potential risk when using a wrench: sensor damage / glass break.
Max. torques: 7 Nm
Electrode with plastic housing (SMARTPAT ORP 1590 ;3/4 NPT threads):
•Apply sealant to NPT thread acc. to your needs, e.g. PTFE tape or liquid sealant.
•It is usually sufficient to tighten the NPT thread by hand. Potential risks when using a wrench: sensor damage
(e.g. glass break); overtightening of the thread. Max. torque for a metal thread connection: 9 Nm
