The Bürkert neutrino transmitter Type 8202 is
a compact device designed for the measurement of:
- the pH in clean liquids or liquids containing
solids, sulphides or proteins.
- or the oxidation-reduction potential in clean
liquids or liquids containing solids, sulphides or
proteins which may present low conductivity.
The transmitter consists of a replaceable
standard 120 mm pH or ORP probe, screwed
in a sensor holder with integrated Pt1000 temperature sensor. This ensemble is plugged-in
and screwed with a nut to an enclosure with
cover, containing the electronic module. Thus
the Bürkert Transmitter facilitates short installation and maintenance effort.
The neutrino transmitter Type 8202 is a 2-wire
device with a 4-20 mA current output.
The device Type 8202 converts the measured
signal, computes the output signal, which is
provided via a free positionable M12 fixed connector or on a terminal strip via a cable gland.

8202
ELEMENT neutrino
Principle of operation
The 8202 neutrino device can be used as a pH or a ORP transmitter according to the probe version mounted into the holder. The pH or redox probe is
a glass membrane with variable selectivity according to the pH or the redox, which must be calibrated with buffer solution before the installation of the
transmitter into the pipe.
When a pH probe is immersed into the solution a difference in potential is formed due to 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).
The pH sensor can be calibrated in 1-point (Offset at pH 7) or in 2-points (Offset at pH 7 and Span at pH 4 or pH 10).
When a redox probe is immersed into the solution an electron exchange occurs between the oxidised and the reduced state of an electrolyte. The
generated cell voltage is the oxidation-reduction potential that is directly proportional to the redox value. The ORP sensor can only be calibrated in
1-point (Offset).
The transmitter is a two-wire device, which requires a power supply of 12 V DC up to 36 V DC and delivers a 4... 20 mA standard signal proportional to
the pH or to the redox potential as output signal.
Installation
The 8202 pH/ORP ELEMENT neutrino transmitter can be installed into any adaptor with G1½” external threaded sensor connection by just fixing the
main nut. Select the required adaptor according to specific requirements of the sensor and material (temperature and pressure), and install it in a vertical
position or with an angle of ±75° max. against the vertical onto an horizontal pipe. For mounting on a tank or direct mounting on a pipe (DN100 or DN110),
an adaptor with a G1½” external threaded sensor connection must be used.
After having connected the pH or redox sensor to the Type 8202 neutrino transmitter and having calibrated the unit, cautiously install the complete unit
on the fitting. In order to get reliable measurement air bubbles must be avoided.
Please ensure that the mounting location provides a continuous and complete immersion of the probe in the flow stream.

Note:
When the transmitter is mounted with any 120 mm pH or ORP
probe, without temperature sensor, with PG13.5 head from the
market please take care of the In-line installation instructions
The probe must continuously be immersed into the measuring fluid in order to protect it from drying out.
The transmitter must be protected from constant heat radiation and other environmental influences, such as direct exposure to sunlight.
