3.1 General notes on installation
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected.
DANGER!
Observe the national regulations for electrical installations!
WARNING!
During installation of the device make sure that you use ESD (electronic discharge) protection
equippment.
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.

INFORMATION!
Inspect the cartons carefully for damages or signs of rough handling. Report damage to the
carrier and to the local office of the manufacturer.
INFORMATION!
Do a check of the packing list to make sure that you have all the elements given in the order.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
3.2 Storage and transport
CAUTION!
Do not store the sensor tip dry. This will shorten lifetime considerably.
Always store the ORP sensor tip wet in a 3 molar KCl solution when not in use. Saltless water
must be avoided since this would leak the KCl ions. The original packing in which the sensor tip
was delivered contains a plastic tube with KCl solution and therefore is suitable for storage and
transport.
• Since the ORP sensor is made out of glass it is very fragile. Avoid shocks of any kind.
• Do not touch or scratch the platinum electrode.
• Store the sensor in its original packaging in a dry, dust-free location. Keep it away from dirt. If
necessary, clean it as described on page 21.

3.3 Installation procedure
WARNING!
During installation of the device make sure that you use ESD (electronic discharge) protection
equippment.
Because a new ORP sensor needs to be calibrated before it is installed into its final measuring
location, it is important to follow the installation order:
1 Unpack the sensor.
2 Connect the sensor to the junction box or directly to the process control system.
3 Calibrate the sensor.
4 Install the sensor into its final measuring location.
The required steps are explained in the following sections.
3.4 Pre-installation requirements
SMARTSENS ORP 8510
CAUTION!
•
Never touch or scratch the platinum electrode of the sensor.
•
Store the sensor in its original packaging in a dry, dust-free location. Keep it away from dirt. If
necessary, clean it as described on page 21
Figure 3-1: Unpacking the sensor
.

Unpacking the sensor
• Remove by gently twisting and pulling the protective cap from the sensor 1.
• Lay the sensor on a soft mat/tissue 2.
• Leave the protection cap of the VP connector on the connector, as long as the sensor is not
connected to the cable.

equippment.
CAUTION!
Moisture inside the sensor connector must be avoided! Moisture may cause a shortcut and
deliver erratic readings!
If moisture has entered the connector dry it with air (e.g. hair blower).
Figure 3-2: Connecting the cable to the sensor
Connecting the cable to the sensor
• Ensure that both cable and sensor connector are absolutely dry 1.

3.6 Installing the sensor
3.6.1 General installation instructions
The platinum electrode 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). Doing otherwise might cause internal air bubbles to float into
the platinum electrode. This would interrupt the electrical contact between the inner buffer
solution and the glass surface.

4.2 Troubleshooting
Problem Possible cause Remedy
The ORP sensor
does not deliver a
signal.
The ORP sensor
delivers an
unstable signal.
Mechanical damage of the
glass, e.g. small cracks.
Open circuit Check the cable wiring of the sensor cable on the junction box.
The diaphragm in the
reference half cell does
not provide good contact
to the process medium
due to drying up or
coatings.
Exchange sensor.
Otherwise connect the sensor to the primary master e.g.
PACTware
damage.
• Clean the diaphragm with hot soap or acid using a soft tissue
(details on page 21).
• Submerge sensor in water and increase the temperature to
+50...+60°C / +122...+140°F.
• Submerge sensor in 3 molar KCl solution at ambient temperature.
The decrease in temperature will cause the reference half cell to
suck in KCl solution through the diaphragm and regenerate the
diaphragms functionality.

5.1 Maintenance
5.1.1 Cleaning
INFORMATION!
Recalibrate the sensor after each cleaning procedure
• Slight dirt residues or dust: Rinse the sensor tip with demineralised water and clean it with a
soft tissue.
• Oily and greasy coatings: Remove with a warm soap solution and rinse with demineralised
water.
• Hardness deposits or metal hydroxide deposits: Soak the sensor tip including diaphragm in
10% citric acid or hypochloric acid for a couple of minutes and rinse the complete glass shaft
of the sensor with demineralised water.
• Biological fouling: Soak the sensor tip including diaphragm in 10 % pepsin solution for
minimum 3 hours and afterwards rinse the complete glass shaft of sensor with demineralised
water.
5.1.2 Aging and re-calibration
SERVICE 5
During operation, but already during storage, ORP sensors age due to poisoning effects of the
inner buffer system. Therefore it is important to re-calibrate the sensor in regular intervals.
Consider status messages and diagnostic information.
INFORMATION!
The lifetime expectation depends heavily on the application. The right choice of the sensor type is
very important.
5.2 Availability of services
The manufacturer offers a range of services to support the customer after expiration of the
warranty. These include repair, maintenance, technical support and training.
INFORMATION!
For more precise information, please contact your local sales office.

6 TECHNICAL DATA
6.1 Measuring principle
6.1.1 ORP measurement
The oxidation reduction potential, ORP in short, is the measurement for the concentration of
oxidising and reducing agents in water. Its value is influenced both by pH and temperature. ORP
is a sum parameter that gives no information on the concentration of a single substance in a
mixture.
ORP measurements are used to monitor chemical reactions involving electron transfer. In
drinking water treatment it can be found in ozone treatment and the removal of iron, manganese
and nitrate as well as in disinfection steps. In swimming pools the German DIN 19643 requires
ORP measurements as a hygiene parameter and decrees maximum and minimum values for
fresh water, pool water, and salt water. In wastewater treatment ORP is measured in the
denitrification process and in detoxication of industrial wastewater.
The ORP sensor consists of a measuring electrode of platinum or gold and a reference of e.g.
Ag/AgCl. The potential of the measuring electrode changes with the concentration of reducing
and oxidising agents and is measured against the reference. The measured values can be
recalculated to fit literature values based on NHE (normal hydrogen electrode) as reference.

7.1 General description
The open HART® protocol, which can be used for free, is integrated into the sensor for
communication.
®
Devices which support the HART
devices. When it comes to operating devices (Master), both manual control units (Secondary
Master) and PC-supported workstations (Primary Master) are used in, for example, a control
centre.
®
HART
field devices include measuring sensors, signal converters and actuators. The field
devices range from 2-wire to intrinsically safe versions for use in hazardous areas.
®
The HART
data are superimposed over the analogue 4...20 mA signal via FSK modem. This way,
all of the connected devices can communicate digitally with one another via the HART
while simultaneously transmitting the analogue signals.
When it comes to the field devices and secondary masters, the FSK or HART

(USB interface). There are, however, other connection variants which can be seen in the
