Melexis has introduced the MLX90614 IR thermometer, which is incorporated in a silicon chip with a thin, micromachined membrane heated by the IR radiation of a remote object. The heating is detected by on-chip thermocouples followed by a signal conditioning circuit that amplifies and digitizes the thermocouple voltage and calculates the object temperature using stored calibration parameters. The non-contact thermometer system, enclosed in a TO-can, provides an operating temperature range of −40 °C to 125 °C and an extended range of −70 °C to 380 °C and maintains a temperature resolution of 0.01 °C. The MLX90614 has an accuracy of ±0.5 °C in the object temperature range of 0 °C to 50 °C and ±1°C outside that range. Two versions of the device are available, one for 3-V supply operation, that is ideal for handheld, battery-operated instruments, and one for 5-V.

Allegro MicroSystems has announced the A139x series of new linear Hall-effect sensors that provide a voltage output directly proportional to an applied magnetic field. The new models, ideal for battery-operated applications, run from 2.5- to 3.5-V power supplies and consume only 10 mW in the active mode, with a draw of 4 mA. Current consumption can be reduced to less than 25 μA through the addition of a user-selectable sleep mode during which the output of the devices is in a high-impedance mode (not a valid state). This feature allows multiple A139x sensors to be connected to a single A/D converter input. The four models are differentiated by their gains; the A1391, 1392, 1393, and 1395 provide 1.25 mV/G, 2.50 mV/G, 5.00 mV/G, and 10.0 mV/G, respectively.

The D-510 series of PISeca capacitive gauges from Physik Instrumente perform high-precision, noncontact measurements of geometric quantities representing displacement, separation, position, length, or other linear dimension against any kind of electrically conductive target. The new gauges feature the following: subnanometer resolution over measuring ranges down to 500 μm, bandwidths to 10 kHz, high temperature stability, and linearity to 0.1%. The company uses a special guard-ring electrode to shield the sensor electrode from boundary effects. In addition, the sensor signal conditioning electronics of the D-510 family are equipped with PI’s ILS linearization circuit. PISeca capacitive sensor systems can be operated in multichannel configurations and combined with nanopositioning actuators for closed-loop control applications.

MTS Systems Corp has developed the R-series analog magnetostrictive position sensor based on the company’s Temposonics design platform. The new sensor can simultaneously produce outputs for two independent magnet-marker positions with a dual-channel electronic design, thus enabling users to measure two parallel or relative motion axes with a single sensor. The R-series sensor can also simultaneously measure a single magnet marker’s position and velocity and can be configured for factory or field to provide either the rate of motion magnitude only (speed) or the magnitude and direction (velocity). The speed range has been expanded, covering 25 mm/s to 10 m/s, with a speed sensing resolution of 0.1 mm/s. Field programming can be performed with handheld, DIN rail-mounted, or PC-based programmers. MTS Systems Corporation, Sensors Division, 3001 Sheldon Drive, Cary, NC 27513, http://www.mtssensors.com

RheoSense has introduced the Viscometeron-a-Chip (VSS), a viscosity measurement instrument that can provide precise and repeatable characterization of various liquids. The VSS can eliminate the need to send viscosity measurement samples to an off-site laboratory for batch-to-batch consistency checks. The chip measures the viscosity and the temperature as the test liquid flows through a microchannel on the chip and an integrated microslit rheometer. Non-Newtonian viscosity is extracted by a rigorous Rabinowitch correction, after which the measurement data are sent for display and analysis to a microcontroller-based readout circuit. A liquid dispensing pump is supplied as part of the system. Wide shear ranges up to 106 L/s can be measured from 10−2 to about 104 poise.

The SLF-500 ultrasonic liquid flowmeter from Flow Technology is a clamp-on instrument that measures bidirectional flow through metal, plastic, and even lined pipes without altering the piping. Typical applications include corrosive chemicals in the process industry and any installations where it is preferable not to have an instrument exposed to the process fluid. The operating principle of the meter involves a time-difference calculation method of ultrasonic wave propagation. The SLF-500 does not cause a pressure drop and provides fast speed of response. It can be used on lines with diameters from 1 in. to 12 in. without recalibration and will cover a wide range of flow rates. The instrument offers an accuracy of ±2% of reading (in the operating range of 3.3 ft/s to 33 ft/s), ±0.066 ft/s in the range below 3.3 ft/s; the repeatability is ±0.2%.

Dimetix has developed the DLS-B, a distance laser sensor that can measure absolute distances to natural and reflective targets up to 500 m with ± 1.5 mm precision. It is possible to determine positions to objects that are difficult to access or have very high surface temperatures. The measurement rate is influenced by the target. If the laser light is reflected well by the target, fast measurement rates can be achieved (up to 0.15 s in tracking mode). The DLS-B can handle moving targets in which the measured distance is the mean value between the distance at the start and end of the measuring process. The instrument incorporates a class II laser—less than 1 mW output—power normally used in classroom demonstrations, laser pointers, aiming devices, and range-finding equipment. The DLS-B can be connected to an external display via RS-232 and RS-422 interfaces. Dimetix AG, Degersheimerstrasse 14, CH-9100 Herisau, Switzerland, http://www.dimetix.com

Hart Scientific’s model 1620A, called the DewK, is a paperless temperature and humidity data logger with wireless, Ethernet, and RS-232 communications. The instrument accepts inputs from up to two sensors and allows sensor hot-swapping; each sensor contains its own calibration data. An H probe reads temperature to ±0.125 °C over its calibrated range of 16 °C to 24 °C and measures humidity to ± 1.5% RH from 20% RH to 70% RH. An S probe reads temperature to ±0.25 °C over its calibrated range of 15 °C to 35 °C and records humidity to +2% RH from 20% RH to 70% RH. The 1620A can store up to 400 000 date- and time-stamped measurements, which can be sent to a PC in real time. An unlimited number of instruments can be simultaneously monitored by adding the company’s LogWare III software.

The FlowCAM-CX from Fluid Imaging Technologies is a color imaging particle analyzer that integrates microscopy and flow cytometry into one instrument. It collects digital color images at speeds claimed to be unattainable by traditional microscopy. Users can identify and analyze particles and cells using the 23 parameters collected for each image. The FlowCAM-CX also uses fluorescence and laser scatter for added particle sensitivity. The company’s VisualSpreadsheet software enables analyzers to capture data for each image and present those data in an image-based spreadsheet. Collected data sets are then used to construct graphical representations such as particle size and shape distributions. The new analyzer is available in portable or benchtop models.
