Metering & Monitoring

Meggitt Sensing Systems has introduced a line of Endevco acoustic sensors and instrumentation for use in automotive NVH, cabin noise, vibro-acoustic testing and appliance noise evaluation

The instruments are also suitable for wind tunnel testing and other critical sound and noise measurement applications.

Endevco pre-polarised condenser measurement microphones, available in 1/8in, 1/4in and 1/2in diameters, are offered in free-field, pressure, low-cost-array and random-incidence types and can be used to meet IEC and ANSI standards.

Array microphones offer a lower overall per-channel measurement cost and are directly compatible with Isotron (IEPE-type) signal conditioning.

They can be used as drop-in replacements within existing accelerometer test system setups for as-needed precision noise measurements.

Models may be purchased as standalone units or in a microphone and low-noise preamplifier combination with Iteds onboard memory storage capabilities, facilitating their use within larger channel count applications.

All microphones are constructed with a stainless-steel protective grid case and housing, as well as a special stainless-steel-alloy diaphragm.

Available for use with Endevco precision measurement microphones is a full range of low-noise Isotron preamplifiers, handheld calibrators and accessories.

All acoustic sensors and instrumentation are covered by a five-year product warranty.

IMI Sensors, a division of PCB Piezotronics, has introduced its 682A09 ICP in-line 4-20mA vibration transmitter, which can turn existing accelerometers into 24/7 vibration-monitoring sensors.

Model 682A09 installs in-line with any industrial accelerometer and converts the vibration signal to a 4-20mA velocity output that can be trended with PLC, DCS or Scada control-room systems.

Its sleek design installs right into the cable run; no DIN rails, cabinets or special power are required.

Customers can take their existing accelerometers and turn them into 24/7 vibration-monitoring devices for their most critical machinery.

The model 682A09 is a stainless-steel, hermetically sealed design capable of operating in the harshest environments with two-pin MIL connector input and three-pin MIL connector output.

It accepts a 100mV/g analogue signal, converts to 4-20mA output and operates off of loop-power supplied by the PLC, DCS or Scada system.

In addition, the 682A09 outputs the 100mV/g analogue signal via its three-pin output connector.

The analogue signal can be run to a central collection point, allowing the user to maintain the FFT capability of the original system.

High Performance Oxygen and Moisture Analyser

Cambridge Sensotec’s latest addition to the successful Rapidox range of analysers is the Rapidox 3100D H2O and Oxygen Dual Gas Analyser.  This instrument adds a high-accuracy dewpoint sensor to a fast oxygen sensor to produce a bench-top unit with impressive performance.

Dewpoint is measured down to -100°C (-85°F) and it can be displayed in terms of °C, °F dp or ppmV.  Oxygen is detected using Cambridge Sensotec’s fast-responding zirconia sensor which comfortably measures oxygen levels from 100% purity right down to 10 e-20ppm.  This sensor has an impressive response time of below five seconds for a 90% response to an oxygen step change.

Relative Humidity and Dew Point solutions from Michell

Michell Instruments have released a new edition of their moisture and humidity product catalogue, which contains comprehensive information on their range of relative humidity transmitters and sensors, dew point transmitters and humidity calibration instruments.

As well as information on new products such as the MDM300 portable dew-point hygrometer and PC62 relative humidity probe, the catalogue also contains a handy guide to the measurement of humidity, which explains common equations as well as terms and conventions used in the industry.

TACTILE SURFACE PRESSURE INDICATING SENSOR

Pressurex® is a thin sensor film that reveals pressure distribution and magnitude between any two contacting or impacting surfaces by instantaneously and permanently capturing and  recording a pressure profile by changing color.

SDI-12 submersible level transmitter offers high accuracy and stability

A new range of submersible hydrostatic level transmitters has been launched, which can be used in depths of up to 200 metres. The transmitter offers an SDI-12 digital output and an inbuilt high accuracy temperature sensor.

The SDI-12L range of submersible level transmitters from Impress Sensors & Systems Ltd uses either a stainless steel silicon-based pressure sensor or a ceramic pressure sensor in marine-bronze. Both versions use piezoresistive technology, which provides long term stability and repeatability of measurements.

Ex rated Explosion Proof Housing for Optical Sensor Range.

http://www.engineeringmaintenance.info/images/stories/Leuuze%20electronic%20PR%20pic.jpgLeuze electronic’s explosion proof sensor range is expanded by a protective housing which enables nearly 200 small optical sensors to be used in EX zones.

Leuze electronic have extended their range of explosion proof optical sensors with several new versions, plus a range of innovative new protection housings.
