Acoustic sensors for pump monitoring
SITRANS DA400
Leakages on delivery valves of oscillating positive displacement pumps (e.g. piston pumps manufacturer) can be detected by measuring cavitation.
The acoustic diagnostic device consists of cavitation sensors and an analyzer unit which supplies the sensors with electrical energy and detects, filters and evaluates the measured signal and outputs an alarm signal on exceeding a defined limit value.
Acoustic sensors for material flow monitoring
SITRANS AS 100
Acoustic sensors monitor high frequency emissions generated by friction and the impact of flowing material or mechanical parts
SITRANS CU 02
Alarm control unit for use with SITRANS AS 100 acoustic sensor

Using acoustic technology to detect subtle changes in the sounds produced during grinding, these systems produce extremely precise feed rate control when the wheel is touching the part or the dresser.
Acoustic systems are particularly useful for preventing collisions and detecting machine and tool abnormalities, chipped industrial grinding wheels and dresser faults. |

Roga MI-17 ICP® (IEPE) measuring microphone - Description:
These 1/4"- ICP® (IEPE) measuring microphones are industrial pressure transducers. The model MI-17 have integrated electronics, and can be delivered with sensitivities from 10 to 100 mV/Pa at tolerances of within ± 5 %. Special custom versions are also possible. Power supplies for the microphones can be either a constant current source of 2 - 6 mA (standard version) or a constant voltage source 4 - 30 Volts. Normally the microphones are fitted with BNC-connectors specification (fem.) allowing standard BNC-BNC cables to be used. Other connectors such as TNC, SMB, Lemo or ìdot are also available on request.
These microphones are quite suitable for array applications.

We provide combined density and sound velocity sensors for the continuous online measurement of 3-component liquids. The sensors determine the velocity of sound and density of the liquids and send measurements to the mPDS 2000 V3 evaluation unit for automatic conversion into specific gravity, °Brix, % alcohol, % H2SO4, API gravity and many other concentration readings.
The sensors have a very short response time, allowing you to react immediately to the results and save money by preventing out-of-spec product.
Different materials are available. There are 3A models and intriniscally safe "I" models. All our sensors are designed for rough conditions in the process environment. There are no moving parts and the complete system is CIP compatible. |

PCB Automotive Sensors Debuts High Temperature Preamplifier
Operating to +120 °C for NVH Powertrain & Vehicle Underhood Testing
The Automotive Sensors division of PCB Piezotronics (PCB®) has announced release of a new high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas.
Automotive engineers routinely perform NVH tests in areas around the powertrain, where elevated operating temperatures can present major measurement challenges. Underhood temperatures can peak at +125 0C under normal driving conditions, and can be significantly higher near turbochargers and exhaust system components, such as manifolds and diesel particulate filters. In the past, test engineers were limited by preamplifiers offering temperature ranges to + 70 °C. Model HT426E01 is a 1/2" preamplifier operating from ICP sensor power, terminating with BNC connector and utilizing standard coaxial cables. The model features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight scale.
Common applications include underhood measurements for benchmarking and issue identification, including engine radiated, induction, ancillary and turbocharger noise; near-field measurements on manifolds; mufflers; exhaust after treatment components; and tailpipe noise. NVH groups within OEMs and Tier 1 suppliers involved with testing of powertrain components will benefit most from this product. |
