Rugged Monitoring reveal new OEM fibre optic temperature sensor module

Rugged Monitoring has developed the O201 as a compact din-rail mounted standalone module for OEMs that can be easily installed in equipment that requires fibre optic temperature sensing.

Based on proven Gallium Arsenide (GaAs) technology, this multi-channel  temperature monitor is available in 2, 4, 6 or 8 channels. Up to thirty-two O201 units can be daisy-chained via Modbus, CANBUS or DNP3.0 to construct a 256 channel monitoring system.

Delivering higher accuracy (0.2 °C, relative) and 100% repeatability over a wide measurement range (-269 °C to +300 °C), the O201 monitor does not need calibration or curve matching compensation when measuring temperature in harsh conditions such as EMI, RFI, microwave and high voltage environments.

The O201 has a single ‘system fault’ relay, and an option for an integrated analogue card (up to 8 channels) for outputting measurements as current / voltage levels.

The module is compatible with a wide range of fibre optic temperature sensors from both Rugged Monitoring and other companies. For more information, please contact us.

Lake Shore’s 8600 VSM updated… Noise floor reduced to 15 nemu

Lake Shore Cryotronics continues to up the performance of their 8600 Series VSM, with the release of a new brochure covering the improved noise floor specifications.

The 8600 Series offers a clean, ergonomic design to simplify the researcher’s interaction with the system. For example, a motorised head brings the sample to a comfortable height for easy, one-handed exchange of the sample rods. And combining high sensitivity, rapid measurement speeds, and ease of operation for faster and more accurate measurements further adds to the convenience these systems offer.

Temperature options include a cryostat, high-temperature oven, and single stage variable temperature insert. The combined temperature range of the options is 4.2 to 1273 K, and all three options quickly slide into place and are auto-detected by the system’s software – video demonstration.

8600 Series Features

  • Noise floor now 15 nemu
  • 10 ms/pt data acquisition rate
  • 5000 Oe/s field ramp rate
  • Rapid, repeatable temperature option exchange
  • High stability: ±0.05% per day
  • Fields to 3.26 T
  • Widest available temperature range: 4.2 K to 1273 K

The magnet poles are also easily adjusted with a specially designed indexed positioning system that allows the pole gap to be set at one of six repeatable positions, eliminating the need to recalibrate after each change.

Lake Shore’s new instrumentation on show at ICEC-ICMC from this afternoon

Lake Shore’s will be demonstrating some of their new instrumentation from today at the ICEC-ICMC Conference in Oxford. This next generation range of instruments offer higher levels of precision and more convenience for engineers, QC technicians, and lab researchers.

The Model 155 MeasureReady™ precision I/V source is ideal for demanding scientific applications requiring a precise low-noise supply of current or voltage, for example electronic material characterisation.

Lake Shore Model 155 Precision I/V Source Source

Two models are available; a DC only version, and the 155-AC model that can supply up to 1 W from DC to 100 kHz over a broad output range. These power supplies deliver a solid foundation for I/V curve, Hall effect, and other fundamental measurements.

The joint Lake Shore and Elliot Scientific team will also be happy to talk about the new F-series Teslameters, compatible Hall probes and 2Dex™ Hall sensors for challenging applications.

The F41 single-axis and F71 multi-axis teslameters work equally well on a benchtop or in a rack. The novel TiltView™ display makes them easy to operate even when mounted in the bottom of a rack. The designers have also ensured that probe swapping is quicker by incorporating a compact quick-release connector and integrated calibration data for all probes.

For more information, please contact us.


ICEC27-ICMC 2018 opens next week. Meet Lake Shore on the exhibition days.

The International Cryogenic Engineering (ICEC) and Materials (ICMC) Conferences are taking place in Oxford from September 3rd to the 7th.

From near absolute to over one thousand degrees – Lake Shore have a sensor to suit

With the UK’s record breaking hot weather continuing, we thought you might like to know that Lake Shore Cryotronics offer four types of sensor for temperature measurement:

Diodes
A diode temperature sensor is the general name for a class of semiconductor temperature sensors. They are based on the temperature dependence of the forward voltage drop across a p-n junction. The voltage change with temperature depends on the material. The most common is Silicon, but Gallium Arsenide (GaAs) and Gallium Aluminium Arsenide (GaAlAs) are also used.

Resistors
These sensors are based on the change of resistance with temperature, and can be classified as positive temperature coefficient (PTC) or negative temperature coefficient (NTC). Platinum RTDs are the best example of PTC resistance sensors.

Capacitors
Capacitors are also used for low temperatures, but usually not for temperature measurement. Capacitance temperature sensors have the advantage of being insensitive to magnetic fields, but they commonly experience calibration shifts after thermal cycling.

Thermocouples
Thermocouples are only useful where differential temperature measurements or low mass are the main consideration. They must be calibrated in-situ as the entire length of the wire contributes to the output voltage if it traverses a temperature gradient.

Each type sensor has its own particular advantages in terms of temperature range and response, as well as design features and drawbacks, so Elliot Scientific recommends contacting us to discuss your application and its requirements.

Lake Shore also do some nice instruments to go with their sensors!

 

 

 

 

 


Laser Focus World features Siskiyou IXF mounts on cover for Los Alamos/UNM story

The July issue of Laser Focus World magazine uses a photo of a YLF:Yb crystal mounted between two top-adjustable Siskiyou IXF monolithic tip/tilt flexure mounts to illustrate their feature story on an all-solid-state optical cryocooler developed by the Los Alamos National Laboratory and the University of New Mexico.

Solid-state optical refrigeration uses anti-Stokes fluorescence to cool macroscopic objects to cryogenic temperatures without the annoying vibrations typically introduced by mechanical cryocooling systems.

The crystal was excited by a low power linearly-polarised continuous-wave fibre laser by IPG Photonics, while the temperature was monitored with a calibrated DT-670-SD silicon diode from Lake Shore Cryotronics.

Coupling the laser light to the crystal was achieved by using an astigmatic Herriott cell, with the optics held in vacuum compatible Siskiyou IXF flexure mounts…  known for their excellent mechanical and thermal properties.

Researchers in the UK or Ireland wishing to replicate this experiment can contact us for research lasers from IPG Photonics, sensors and instrumentation from Lake Shore Cryotronics, and the full range of mounts and stages from Siskiyou. Elliot Scientific can also be approached to supply optics and custom machined parts as well.

The full paper describing the experiment can be read here on nature.com.

Using CryoLab to measure Seebeck coefficients: Video from DEMCON kryoz explains

The Seebeck effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference.

By using the CryoLab from DEMCON kryoz, it is possible to measure the Seebeck coefficient of a material sample, wire or thin film from 373 Kelvin down to cryogenic temperatures. In this informative video, DEMCON kryoz demonstrate how such measurements are made using their equipment. For more information, please contact us.
