Capacitive Sensors, Capacitive Position
Sensors and Their Applications |
| |
 Physik
Instrumente (PI): Many application areas today require the highest
of measurement accuracies, with resolutions in the nanometer or
subnanometer realm. Examples range from semiconductors and biotechnology
through quality assurance and automotive to metrology and microscopy.
Even in “normal” machining, more and more automated tasks require
high-accuracy positioning, which means that suitably high-precision
measuring equipment is essential. This places high demands on the
sensors used. In addition, the sensors must be as easy to integrate in
the application as possible, and usually must also exhibit excellent
dynamic performance. The accuracy and repeatability of the sensors used
is a major determinant of the performance of any positioning system.
Anyone requiring the maximum possible accuracy—in the nanometer or even
picometer realm—will be using capacitive sensors. One specialist in the
area of nanopositioning systems manufacture is PI (Physik Instrumente),
a company which has long been a moving force in the development of
high-precision capacitive sensors, capacitive position sensors, mostly
for use in its own products. Today, capacitive sensors, capacitive
position sensors of various different types, some with resolutions down
into the subnanometer realm, have their own place in the product
palette. Capacitive sensor metrology has more to offer than just high
accuracy: The sensors provide non-contact measurements of the actual
position of the moved object directly—accuracy, stability and bandwidth
are substantially better than those obtained with conventional LVDT or
SGS sensors. ... |

New Contact-Free Capacitive Level Switch
Allows For Complete Media Compatibility |
| |
 Sensortechnics’
new CLW series detects point levels of liquids and granular or
pulverised materials without contacting the media. The user can easily
adjust a high and low switch point with a hysteresis of less than 25 mm.
The CLW device uses a new non-invasive capacitive sensor technology and
allows for complete media compatibility and sterility. Due to its
miniature size these level switches can be perfectly integrated into OEM
devices. The CLW sensor can be mounted to the outside of a container or
vessel and is able to measure through almost any non-metallic wall
material. The level switch is highly flexible and can be easily
calibrated to measure to the desired levels, media and application
set-up. The CLW series achieves a very high accuracy and reliability due
to an additional reference electrode which compensates for all changes
in ambient environmental conditions such as temperature and humidity.
Additionally, Sensortechnics can also provide continuously measuring

Capacitive sensors with new technology |
| |
 The
latest range of capacitive sensors from Micro-Epsilon is based on
a completely new technology. A special ceramic substrate provides the
capaNCDT CSH (Hybrid) sensors with extreme temperature stability. New
sensor geometries are also possible which enable the production of a
sensor with a height of 4mm. These flat sensors are called capaNCDT CSH-FL.
Using two drilled holes on the sensor, the flat sensors can be mounted
quickly and easily; as before, the cylindrical sensors can be mounted by
clamping The sensors are also available for use in ultra-high vacuums (UHV)
and clean rooms where, for example, freedom from contamination of the
materials is also important. Due to the integrated cable on the sensor
side, there are two significant benefits: installation space is
significantly reduced and the risks arising from an additional plug
connector, e.g. accidental detachment, are eliminated. The new
technology and the modular design of the sensor enable Micro-Epsilon to
respond very quickly to customer requirements. The CSH sensors are
currently available with measuring ranges between 0.2mm and 1.2mm. Other
measuring ranges are being developed. The hybrid sensors ... |

New Capacitive Sensor Technology Allows
for Continuous and Contact-Free Level Measurement |
| |
 Sensortechnics’
CLC series uses a new contact-free capacitive sensor technology to
continuously measure the fill level of liquids as well as granular or
pulverized materials. The miniature sensor can be easily mounted to the
outside of a container or vessel and is able to measure through almost
any non-metallic wall material. The level sensing range of the standard
device is up to 10 cm which can be enlarged in special multi-sensor
configurations. The non-invasive design, with no contact between the
sensor and the fluid, eliminates all media compatibility and sterility
issues. The device is highly flexible and the user can easily calibrate
the sensor to measure to the desired levels, media and application
set-up. The CLC series achieves a very high accuracy and reliability due
to an additional reference electrode which compensates for all changes
in ambient environmental conditions such as temperature and humidity. As
an optional safety feature the sensor can be supplied with an extra
sensing pad to detect if a container is actually present or not. The CLC
sensor offers an analog voltage output as well as a digital interface.

Capacitive Sensors - Aggressive media
safely detected |
| |
 Baumer
Electric: In quite a number of fill level applications there are
liquids to be detected which require sensor housings and media
containers to be made of materials of strongly improved properties due
to their chemical reactivity. The new Baumer capacitive sensors provide
interesting new approaches to many of these challenging cases. Since the
sensors' electrical field of detection is capable of penetrating through
insulating materials such as plastics, glass, cardboard etc., non
invasive detection of both liquids and solid matter is possible from the
outside. Capacitive sensors can therefore monitor fill levels in closed
containers whilst being attached to the outside container wall. Compared
to sensing methods requiring direct contact with matter, there are a
number of advantages. On one hand, this approach provides an excellent
protection for the sensor itself, which assures a long live expectancy
as well as a high degree of process safety. On the other hand, the
medium to be detected or monitored cannot be contaminated by the
sensor’s housing. The detection behaviour of capacitive sensors is
influenced by the dielectric constant of the surrounding materials.
Certain limitations apply when detecting liquids and objects exhibiting
a low dielectric constant using the existing, flush-mounted capacitive
sensors ... |

 Baumer
Electric: Baumer’s IFRH series of inductive high temperature sensors
have been designed for operating temperatures ranging from -25 °C to
+180 °C. The two part proximity switches intended for flush front face
installation are available in M8, M12 and M18 designs with chromium
nickel steel housings. With an overall length of a mere 30 mm, the M8
sensor is ideal for installation under conditions of limited space.
Depending on the housing size, the nominal switching distance ranges
from a minimum of 1 mm up to a maximum of 5 mm. An FEP jacketed cable
allows the processing electronics to be separated from the actual sensor
head and to thus be easily and protectively installed outside the hot
range. The operating voltage range lies between 10...30 VDC, while the
protection class is IP 67. In addition, Baumer also offers capacitive
high temperature sensors for detecting nonmetallic components in hot
environments. ... |

sub-nanometre resolution |
| |
 Only
a short time after introducing its new single-channel measurement
systems, Micro-Epsilon is now offering a new capacitive multi-channel
measurement system, which guarantees extremely high resolution and
accuracies. According to the manufacturer, the new capaNCDT500 provides
a resolution in the range of hundredths of a nanometre and supersedes
the existing capaNCDT600 series. An Ethernet port with 24-bit resolution
is available, so that data obtained can be output as error-free as
possible. The new system is modular in its design and can accept up to
eight measuring channels, depending on requirements. For this, the
controllers, in all the major European card formats, are inserted in the
housing. A version with an integrated preamplifier, as well as one with
an external preamplifier, are available, which enables cable lengths of
up to 20m between sensor and controller. The sensors operate virtually
independent of temperature and so can be used at ... |

Level measurement in cavities with only
4mm diameter |

SNT
Sensortechnik AG: Many industrial applications can be solved with
the miniature ultrasonic sensors series UPS, where optical, inductive or
capacitive sensors might have problems with detection. Furthermore with
the UPS sensors with analogue output a precise distance or level
measurement can be realized, with a precision of approx. 0.3mm, with
0…10V or 4…20mA output. The special version “FOCUS Beam” (center on
picture) has a focusing device for the ultrasound. It has been
particularly successful in various applications. It proved its advantage
in the detection through very narrow openings. Since the FOCUS Beam does
not have any disadvantageous blind range, one can place it very close
(few millimeters only) to the opening of a cavity. There the beam is
only 3mm wide in diameter. This allows e.g. to measure the level in only
4mm wide cavities with an accuracy of only few 1/10mm. The other special
version "CP" (Chemical Protection, right on picture) has a PTFE
diaphragm with a protective sleeve. This can be used as a level sensor ... |
