MEMS Barometric Pressure Sensor


The new BMP085 enters the market as the smallest and most accurate micromechanical (MEMS) pressure sensor with a digital I2C output. Maintaining pin and software compatibility with Bosch Sensortec's 1st generation SMD500, customers can now achieve even greater performance without impacting designs already in production. With a 25 percent package height reduction and a remarkable reduction to a seventh in standby current to 0.1 µ, BMP085 makes way for navigation applications in the mobile space. Both enhancements add to the attractiveness of the device for manufacturers of mobile consumer electronics. But without in any way degrading sensitivity – the 0.03 hectopascal maximum resolution of the BMP085 is an optimum enabling the sensor to respond to differences in altitude of just 25 cm. BMP085 as part of a mobile platform can thus enable new levels of vertical accuracy at a fraction of the overall system cost ...

Contact-free DC-Operated Rotary Position Sensors Measure Angular Displacement of Rotating Elements up to 120º


Pennsauken, NJ, May 2, 2008 - Macro Sensors introduces a new series of contactless, fractional-turn, rotary position sensors that provide an absolute output proportional to shaft rotation over a total range of up 120º. The RSE 1500 Series Rotary RVDT Position Sensors are ideal for measuring the angular displacement of rotating elements such as quarter-turn ball and butterfly valves, air flow dampers, mail sorters, and diverter gates used in packaging and postal sorting machinery. Units are also useful for other limited rotation applications requiring high reliability such as pedal position sensing for mobile equipment such as lift trucks, stackers, golf carts, and lawn tractors, or throttle lever position sensing in boats, cranes, and articulating-arm utility service vehicles.


Although their shafts can rotate a full 360º, the RSE 1500 Series Rotary RVDT Position Sensors measure shaft angle position over a nominal range of 120º. Units can operate in 0° to 30°, 60°, 90°, or 120° rotation ranges. Contactless inductive technology enables these rotary position positions to offer high accuracy and repeatability with exceptional reliability. Units exhibit a linearity error of less than 0.10% of full range output while operating over temperatures from 0ºF to 185ºF (-20ºC to 85ºC) ...

First Stand-alone 4-20 mA Vibration Displacement Sensor for Machinery Monitoring


Wilcoxon Research, announces the addition of a displacement sensor to its popular PC420 Series of 4-20 mA vibration sensors. The PC420D is the first IEPE displacement transducer and 4-20 mA vibration transmitter packaged as a single sensor. Wilcoxon’s PC420 Series of sensors monitors rotating equipment and outputs a real time 4-20 mA signal proportional to the vibration level. By trending this real time data, plant personnel are able to schedule preventative maintenance activities around planned downtime, saving time and money in costly unexpected repairs.


The PC420D sensor outputs a 4-20 mA signal based on the displacement level of the machine vibration. The 4-20 mA output is determined by first measuring the peak to peak vibration, then converting that level to a 4-20 mA signal. Because balance components tend to dominate the vibration spectrum when viewed in displacement units, the PC420D sensor is able to track the balance component of machines, one of the most sought after parameters. Integrating this signal into an existing PLC, DCS or SCADA system simplifies real time health monitoring because vibration, formerly considered too complex, can now be trended in easily understood units of mils or millimeters of displacement ...

 Central Measurement System Gateway for Complex Applications in the Automotive Industry


IPETRONIK has launched its specially designed “TESTdrive” real-time software that allows users to stay in control of increasingly complex testing tasks within the car manufacturing sector. TESTdrive is a practical all-round tool for jobs such as measurement and diagnosis, stable long-term data capture, online classification, and pre-processing and networking of different measurement variables. The measurement system uses the M-LOG data logger platform as its central synchronizing measurement system gateway. The logger can be modularly configured and expanded to include a wide range of interfaces and external components. In addition to traditional logger functions, TESTdrive can optionally be expanded to include communication protocols that allow it to communicate with the entire range of control systems in a vehicle. The logger also permits synchronous linking of physical variables via access to protocols, error memory, DAQ lists, etc. All data and protocols can easily be accessed and managed, thanks in particular to its user-friendly configuration software, which runs on all computers with current Windows operating systems. The included import tool allows convenient use of all common description files, such as CANdb, A2L and others ...
