Description
5 DESCRIPTION
5.1 Area of application
The device is intended solely for the measurement of:
• the pH in clean liquids or liquids containing solids, sulphides or proteins.
• or the oxidation reduction potential ("ORP") in clean liquids or liquids containing solids, sulphides or proteins
which may present low conductivity.
Thanks to two fully adjustable transistor outputs, the transmitter can be used to switch a solenoid valve, activate
an alarm and, thanks to one or two 4-20-mA current outputs, establish one or two control loops.
5.2 General description
5.2.1 Construction of the 8202
The device comprises:
• a module for measuring process values, comprising:
- a pH or Redox ("ORP") sensor measuring a potential difference (PD) in mV
- a Pt1000 temperature sensor built in the holder of the pH or Redox ("ORP") sensor, measuring a resistance.
• an acquisition / conversion module for the process values measured:
- measured PD acquisition in mV
- conversion of the measured PD into pH units (for a transmitter with pH sensor only)
- acquisition of the resistance measured and conversion into temperature
• an electrical housing which can include a display module. The display module has a navigation button used
to read and/or configure the parameters of the device. The display module is available as an accessory (see
chap. 11).
One version of the device with two transistor outputs and a 4-20 mA output operates on a 2-wire system and
requires a power supply of 14-36 V DC. For such a version, electrical connection is done via an M12, 5-point,
male fixed connector.
One version of the device with two transistor outputs and two 4-20 mA outputs operates on a 3-wire system and
requires a power supply of 12-36 V DC. For such a version, electrical connection is done via an M12, 5-point,
male fixed connector and an M12, 5-point, female fixed connector.
5.2.2 pH or Redox ("ORP") probe
The device can be fitted with a standard probe 120 mm long, measuring the pH or the oxidation reduction
potential ("ORP").
It is screwed into a holder with the built-in Pt1000 temperature probe.
• The pH probe is a glass membrane with variable sensitivity according to the pH. When the pH probe is
immersed in a solution, a difference in potential is formed, due to the hydrogen ions (H+), between the glass
membrane and the solution. This difference in potential, measured in relation to a reference electrode, is directly
proportional to the pH value (59.16 mV per pH unit at 25°C).

To ensure the equipotentiality of the installation (power supply - device - medium):
→ Connect together the various earth spots in the installation to eliminate the potential differences that may
occur between different earthes.
→ Observe faultless grounding of the shield of the power supply cable (see Fig. 18 and Fig. 19).
→ Special attention has to be paid if the device is installed on plastic pipes because there is no direct earthing
possible. Proper earthing is performed by earthing together the metallic devices such as pumps or valves, that
are as close as possible to the device (see Fig. 19).

CALIB TEMPERAT.: choose the type of temperature compensation for the calibration process: either the temperature measured (select "Auto") or a fixed value (select "constant" then enter reference temperature).
→ Calibrate the sensor using one of the following methods:
- CALIBRATION: calibrate the pH sensor in 1 or 2 points (see details hereafter). A calibration process
updates the last calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter).
- PROBE CONSTANTS: enter the offset and/or span values indicated on the pH sensor certificate, if sup-
plied. This input replaces a calibration made by the "Calibration" function above but does not update the last
calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter).
CALIB INTERVAL: read the date of the last calibration (function "Last cal. date") and set the periodicity of calibrations, in days (function "Interval"): the transmitter generates a "maintenance" event by displaying the
icon
and a "warning" event, each time a calibration is due. Set function "Interval" to "0000 days" to ignore the function.
• The "warning" event may be associated with one or other or both transistor outputs (see chap. 9.11.10).
• See also chap. "10.5 Solving a problem".

• In order not to interrupt the process, activate the HOLD function (see chap. 9.12.1).
• Before each calibration, correctly clean the electrode with a suitable product.
• In a 2-point calibration, the buffer solutions used must be at the same temperature.
• Set the periodicity of calibrations in the "Interval" function in the sub-menu CALIB INTERVAL (see above):
each time a calibration is due, the transmitter generates a "maintenance" event and a "warning" event.
1-point calibration
The 1-point calibration procedure is used for quick calibration by adjusting the offset of the measurement graph
with a buffer respectively a calibration solution with a known pH (to calibrate a pH sensor: see page 56)
2-point calibration
The 2-point calibration procedure is used for the precise calibration of the offset and the gradient ("span") of the
sensor measurement graph.
This operation requires 2 buffer solutions: in general a first solution with a pH of 7 and a second solution with a
pH very close to that of the process value to be measured (see page 56).
