Newport has added the model 3040 advanced temperature controller and the 5000 series advanced laser diode drivers to its laser diode instrumentation products.
The 16bit resolution and accuracy allow full control and characterisation of laser diodes, TE modules and temperature sensors, with all parameters presented on a two-line alphanumeric LCD display. The low noise model 3040 controller provides a 32W (4A/8V) bipolar output for operation with thermoelectric coolers.

Buehler Krautkramer’s range of piezocomposite probes are claimed to provide advantages for inspecting coarse grain and highly attenuative materials such as plastics and nylons, allowing NDT techniques to be used for the first time on certain materials.
The use of piezocomposite has resulted in an ultrasonic transducer offering high gain and broad bandwidth. The material is a piezo-electric ceramic/epoxy matrix and is said to have superior ultrasonic performance compared with piezo-electric crystals.

The TQ123 low cost gas sensor from Environmental provides continuous monitoring and alarm for toxic concentrations of methylene chloride.
For operation in laboratory and process environments where methylene chloride is used as a solvent, the sensor uses solid state chemical technology to provide an operating range of 0-1000ppm allowing alarm set points at 100ppm and 300ppm, OES 15 minute and eight hour TWA reference periods. Response time is in seconds.

Honeywell’s photoelectric controller recognises targets while suppressing the background, providing a precise, adjustable sensing distance. The BS series diffuse photoelectric controller operates independently of background colour and material surface properties.
Typical applications include conveyor belt alignment, transfer line process control, detection against light colour or other reflective backgrounds, and wafer detection. Industries include package distribution, food and beverage, and electronic assembly.

A new version of Compact Instrument’s CT7/LSR microprocessor-based laser tachometer has been introduced for applications which require speed measurement to be recorded or logged. It has a pulsed output facility and a switch which allows the instrument to remain ‘on’: the standard CT7 only operates when the ‘on’ button is pressed.
The digital output of the new version makes it suitable for interfacing with computerised data logging systems. Typical applications include condition monitoring and predictive maintenance.

The Fluke 16 digital multimeter with thermometer has a 600V category III rating for safety. It features temperature, microamp and capacitance measurement functions, with autoranging and min/max recording features.
The temperature feature accurately measures extreme variations in temperature from -40 degrees C to 400 degrees C. Using standard equipment adapters such as the 80PK-1 bead probe thermocouple and the 80AK temperature adapter, the device provides fast, accurate reading.

A gauge for vacuum deposition processes, Balzers IMR 260 compact process ion gauge, is available from Pfeiffer Vacuum.
For vacuum measurement from 10-6-1000mbar, reproducibility is +/-2% from 10-5-0.1mbar, covering the whole range of sputtering and evaporation processes. It combines a high pressure hot ionisation gauge and a Pirani in one housing. The on-board electronics use a pressure signal from the Pirani to control the on/off status of the hot cathode that enhances the lifetime of the filament.

ESE from ITP is a manually operated coordinate measuring machine suitable for use in machine shops, foundries, sheet metal working and other types of workshop.
It is equipped with linear scales, each with a resolution of 10 micron. Accuracy is given at U1 = 20 + L/40 and U3 = 30 + L/20. It can be supplied with a cast iron or granite surface table, or it can be retrofitted to an existing table.
Constructed in steel, the robust members produce the rigid structure that is necessary for accurate measuring. Linear travel is along hardened and ground ways. The column travels on one of these ways incorporated in a base which can be mounted directly on a surface table.

Three new modules in the company’s Camio suite of universal, PC-based software are available from LK Co-ordinate Measuring Systems.
The modules allow models created on most CAD systems to drive any CMM which supports the industry-standard DMIS protocol.
The latest modules include one for flexible fixturing. In the existing range are two G-90C vertical-spindle, moving-bridge models, sizes 6.5.4 and 10.10.8 with measuring envelopes of 610 x 508 x 406mm and 1016 x 1016 x 813mm respectively. The spindle and Y-axis beam of these machines are ceramic.
