Inclination Sensor - without measuring
disturbance due to vibrations? |
| |

Each current inclination sensor on the market will be disturbed more or
less by vibrations in the measuring direction. Additional electronic
filters and/or complex algorithms will not solve the problem if the
measuring element is already clipping or due to strong damping reacts
too slow. This result in some cases to extreme tolerances, which cannot
be recognized by the user. The SCHMIDT® Inclination sensor NW
40.100 has been under consideration of the problem – measuring
disturbance caused by vibrations – optimized and measures inclination
angles of movable systems relative to the horizontal plane directly. No
additional filtering or software is needed. Main features of the sensor
are: Angle-linear analogue, binary or digital interface. Fluidically
damped gravitational pendulum. Contact less measuring by rotary field
method without external rotary magnet or shaft attachment. Angle
measuring range up to 360° optionally selectable with an angle
resolution of 2.5 x 10-4 of the total measuring span. High angle
fidelity at angular rates up to 180°/s. Extreme insensitive at
vibrations due to low-tuned resonance frequency of 3 Hz. No signal
clipping at high acceleration levels. ... |

Kistler Offers Right Mold Cavity Pressure
Sensor for any Process |
| |
Complete
portfolio of cavity pressure sensors: Cavity pressure is and remains the
process variable in evaluating the injection molding process and the
quality of the molding. The right choice of sensor and simple and
reliable connection technology are the most important criteria for
success. The size of the sensor is often determined by the size of the
molding. Kistler offers the right sensor for any dimensions –
with front diameters from 1 mm (Type 6183A…) to 6 mm (Type 6152A…), or
miniature sensors with side cable outlet Type 6184A…. There are,
however, other factors that dictate the choice of sensor. For example,
fillers and abrasive materials require sensors with a front coating,
which Kistler offers for all standard sensors in the form of
abrasion-resistant chromium. Last not least, the process determines
which is the right sensor to choose. In low-pressure processes, such as
foam of thermoplastics or polyurethane injection molding, particularly
sensitive high-resolution sensors must be employed. Kistler’s special
low-pressure-processing sensors Types 6172A…, 6177A… and 6178A… have
proven effective in these applications. In addition to cavity pressure,
the combined pressure and temperature sensors ... |

PCB Introduces New Free Field ICP® Array
Microphone for NVH Studies, Sound Pressure Mapping, Acoustic Holography
and Biomedical Research |
| |
Depew,
NY, USA – PCB Piezotronics (PCB®) has debuted Model 130D22, a
combined ICP® free field response pre-polarized array microphone and
preamplifier. The microphone is designed for measuring sound pressure
levels and frequencies in the audible range, and can be used
simultaneously with ICP® accelerometers to simplify test setups. Model
130D22 also incorporates a SMB connector, which is easy to assemble,
provides seamless transition for many data acquisition systems and
software set-ups, and saves time when connecting multiple units, such as
in a large channel array setup. When used with data acquisition systems
that have 2-20 mA constant current supply, the system does not require
additional power supplies. The unit has high sensitivity (45 mV/Pa),
uses standard low-cost coaxial cables, and also has optional TEDS
capability, which allows for ease of use, and traceability. This
acoustic test product is ideal for array set-ups (2 D Pressure Mapping,
Holography); trending and frequency analysis; predictive maintenance on
machinery fans, bearings and other industrial applications; white goods
testing; NVH studies for automotive and ... |

Transducers and Transmitters for General Purpose and Hazardous
Industrial Environments |
| |
Depew,
NY, USA - Series 1500 Transducers and Transmitters from PCB
Piezotronics (PCB®) offer a complete selection for pressure
monitoring in general purpose and hazardous industrial environments.
General purpose units feature a rugged, all-welded stainless steel
construction. The design includes elimination of mechanical fasteners,
washers, o-rings, and fluid fills, greatly enhancing reliability and
long-term repeatability of the units, and making them suitable for a
variety of laboratory, factory, field, or submersible environments. Full
scale ranges are available, from full vacuum to 6000 psi (400 bar), with
accuracies of 0.5%, 0.25%, and 0.1%. Units are supplied with 0-5 VDC;
0-10 VDC; or loop-powered 4-20 mA output signals, with choice of
pressure port and electrical connectors. Intrinsically safe Series 1500
units feature a thin, one-piece stainless steel Monolith pressure
fitting, port and diaphragm design with ½” NPT thread, with optional
Inconel® for H2S & sour gas media compatibility. Sensors are constructed
without adhesives, welds, or fluid fillings, and have been certified
under ATEX and CSA as intrinsically safe for use in hazardous
environments. Transmitters offering intrinsically safe certifications ... |

Type 4005A... – Absolute Pressure
Measurement |
| |
Kistler:
The M5-size piezoresistive pressure sensor Type 4005A... is designed for
measuring absolute pressure in engines. A so-called DCE sensor (DCE =
Direct Chip Exposure), it does not have a steel diaphragm for separating
media, but is exposed directly to the medium.
The piezoresistive silicon measuring element is placed behind a
protective shield and provided with a protective coating. Thanks to a
special coating the sensor is able to withstand typical fuel and
lubricating oil vapours. A good deal of flexibility in mounting is
achieved thanks to the sensor’s compact design, so that it can always be
located in the optimum position for measurements in the intake system.
In addition to small dimensions, this design achieves superb linearity,
low hysteresis and a high natural frequency. Used in conjunction with
the piezoresistive amplifier module, the SCP signal conditioning system
and PiezoSmart® automatic sensor identification, the new Type 4005A...
constitutes a powerful measuring system which is very easy to operate. ... |
