Function and system design
Measuring principle Ion-selective, or more generally ion-sensitive field effect transistors (ISFET) were developed in the 1970s as
an alternative to the glass electrode for pH measurement.
Basics
Ion-selective field effect transistors use an MOS 1) transistor arrangement (→å1) where the metallic gate
(pos. 1) is not a control electrode. Instead, the medium (→å2, pos. 3) in the ISFET is in direct contact with
the gate isolator layer (pos. 2).Two strongly N-conducting areas are diffused in P-conducting substrate
(→å2, pos. 5) of the semiconductor material (Si). These N-conducting areas are current supplying
("Source", S) and current accepting ("Drain", D) electrodes. The metallic gate electrode (in case of the
MOSFET) resp. the medium (in case of the ISFET) forms a capacitor with the substrate below. A potential
difference between gate and substrate (UGS) causes a higher electron density between "Source" and "Drain". A
N-conducting channel (pos. 2) is formed, i.e. a drain current (ID) is induced.
With the ISFET, the medium is in direct contact with the gate isolator layer. Therefore, H+ions available in the
medium, which are located in the medium / gate isolator boundary layer, create the electric field (gate
potential). Depending on the effect described above, a N-conducting channel is formed and a current between
"Source" and "Drain" is induced. Suitable sensor circuits use the dependence on the ion-selective gate potential
to create an output signal proportional to the concentration of the ion type.
pH selective IsFET The gate isolator serves as an ion-selective layer for H+ions. The gate isolator is impermeable to the ions as
well (isolator effect) but allows reversible surface reactions with the H+ions.
Depending on the acidic or alkaline character of the measurement solutions, functional groups in the isolator
surface accept or reject H+ions (amphoteric character of the functional groups). This leads to a positive (H+
acceptance in the acidic medium) or negative (H+rejection in the alkaline medium) charging of the isolator
surface. Depending on the pH value, a defined surface charge can be used to control the field effect in the
channel between "Source" and "Drain".The processes which lead to the creation of a charge potential and
therefore to a control voltage UGS between "Gate" and "Source" are described with the Nernst equation:
At 25 °C (77 °F), the Nernst factor is –59.16 mV/pH.

Important characteristics of
Tophit CPS 471
• Resistance to breaking
This is the most obvious feature of the sensor. The complete sensor technology is embedded in a PEEK shaft.
Only the highly resistant isolator layer and the reference have direct contact with the medium.
• Acid or alkaline errors
A further, important benefit compared with the glass electrode is the considerably reduced number of acid
or alkaline errors in extreme pH ranges. In contrast to glass electrodes, practically no foreign ions can build
up at the ISFET gate. The measuring error of < 0.01 pH (between pH 1 and 13) at 25°C (77 °F) is near by
the detection limit.
The figure below shows the acid or alkaline error of the ISFET between pH 1 and 13 and the comparison to
the glass electrode (two different pH glasses) at pH values 0.09 and 13.86.
a0003867-en
Fig. 3: Comparison of acid and alkaline errors
• Measurement stability and sensor response time
The ISFET response times are very short over the whole temperature range.
With the ISFET sensor, there is no (temperature-dependent) equilibrium setting as in the source layer of a
pH glass of a glass electrode. They can also be used at low temperatures without a deceleration in response
time.Large and fast temperature and pH value fluctuations have a smaller effect on the measuring error
(hysteresis) than with a glass electrode, as there is no stress exerted on the pH glass.
• Reference system
The integrated reference electrode of the sensor is a double-chamber reference system with a bridge
electrolyte. The benefits are an efficient and stable contact between the diaphragm and the reference lead,
and the extremely long poisoning path. The bridge electrolyte is highly resistant to temperature and pressure
changes.

• Isothermic curves
– The Nernst equation defines the dependence of the measuring voltage on the hydrogen ion content (pH
value) and the temperature. It is the basis of pH measuring technology and for ISFET sensors too. A
temperature-dependent value for the potential change per pH value can be worked out from this equation
(isothermic curve, potential change per pH value at a defined temperature).
– The isothermic curves of the ISFET sensor are very close to the theoretical values (→å4). This is further
proof for the high pH measurement precision of the sensor.

Memosens (CPS471D) Maximum process safety
The inductive and non-contacting measured value transmission of Memosens guarantees maximum process
safety and offers the following benefits:
• All problems caused by moisture are eliminated.
– The plug-in connection is free from corrosion.
– Measured value distortion from moisture is not possible.
– The plug-in system can even be connected under water.
• The transmitter is galvanically decoupled from the medium. The result: No more need to ask about
"symmetrically high-impedance" or "unsymmetrical" (for pH/ORP measurement) or an impedance
converter.
• EMC safety is guaranteed by screening measures for the digital measured value transmission.
Data safety through digital data transfer
The Memosens technology digitalizes the measured value in the sensor and transfers it to the transmitter via a
contactless connection. The result:
• An automatic error message is generated if the sensor fails or the connection between sensor and transmitter
is interrupted.
• The availability of the measuring point is dramatically increased by immediate error detection.
• The digital signals are suitable for application in hazardous areas; the integrated electronics are intrinsically
safe.
Easy handling
Sensors with Memosens technology have integrated electronics that allow for saving calibration data and
further information such as total hours of operation and operating hours under extreme measuring conditions.
When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used to
calculate the current measured value. Storing the calibration data in the sensor allows for calibration and
adjustment away from the measuring point. The result:
• Sensors can be calibrated unter optimum external conditions in the measuring lab. Wind and weather do
neither affect the calibration quality nor the operator.
• The measuring point availability is dramatically increased by the quick and easy replacement of precalibrated
sensors.
• The transmitter does not need to be installed close to the measuring point but can be placed in the control
room.
• Maintenance intervals can be defined based on all stored sensor load and calibration data and predictive
maintenance is possible.
• The sensor history can be documented on external data carriers and evaluation programs at any time. Thus,
the current application of the sensors can be made to depend on their previous history.
Communication with the transmitter
Always connect digital sensors with Memosens technology to a transmitter with Memosens technology. Data
transmission to a transmitter for analog sensors is not possible.
The sensor is connected to the cable connection (CYK10) without contact. The power and data are transferred
inductively
Once connected to the transmitter, the data saved in the sensor are read digitally. You can call up these data
using the corresponding DIAG menu.
Data that digital sensors save include the following:
• Manufacturer data
– Serial number
– Order code
– Date of manufacture
• Calibration data
– Calibration date
– Calibration values
– Number of calibrations
– Serial number of the transmitter used to perform the last calibration
• Operational data
– Date of commissioning
– Hours of operation under extreme conditions
– Number of sterilizations
– Data for sensor monitoring.

Chemistry and process (Ex applications)
Process sterilizibility is no problem due to the wide range of applications for the ISFET pH sensor, not only
relating to temperature but also to pH. There is only a small range of high pH values connected with high
temperatures where the sensor is not constantly stable (see "Process"). Media with these characteristics remove
the isolator oxide from the ISFET chip. As this is the pH and temperature range of CIP cleaning media, the
ISFET pH sensor should only be used in combination with an automatic retractable assembly.
Benefits of the Topcal fully automatic measurement, cleaning and calibration system:
• CIP cleaning
The sensor built into the retractable assembly is automatically "moved" out of the medium before cleaning.
In the rinse chamber of the retractable assembly the sensor is cleaned with suitable cleaning solutions.
• Calibration cycles can individually be set.
• Low maintenance costs due to fully automatic cleaning and calibration functions.
• Measuring results are optimally reproducable and the individual value tolerances are very low due to the
automatic calibration.

Repeatability ± 0.1 % of measuring range
Start-up drift Everytime when switching on the measuring device a control loop is set up. During this time the measured
value moves to the true value.
The settling time depends on the kind of interruption and the interruption time:
• Supply voltage interruption, sensor left in medium: approx. 3 to 5 minutes
• Interruption of the fluid film between pH sensitive ISFET and reference lead: approx. 5 to 8 minutes
• Longer dry storage of the sensor: up to 30 minutes
Installation
Installation angle ISFET sensors can be installed in any position, as there is no liquid internal lead. However, in case of an
overhead installation, a possible air cushion2) in the reference system might interrupt the electrical contact
between the medium and the diaphragm.
!Note!
• The installed sensor may be held under dry conditions for maximum 6 hours (also applies to overhead
installation).
• Make sure you comply with the instructions in the operating instructions for the assembly used.

Sensor orientation When installing the sensor, note the flow-past direction of the medium. The ISFET chip should be fixed at an
angle of approx 45° to the flow-past direction (→å12). Fixing at the correct angle is very easy because of
the rotable plug-in head.
When installing the sensor in an assembly, use the engraved serial number on the connection head for correct
sensor orientation. The serial number is always located in the same plane as the ISFET chip and the nameplate
(z-y-direction, →å11).
