Measuring Earth’s magnetic field strength and orientation

The new F71 Multi-axis teslameter from Lake Shore Cryotronics features in an excellent video on the YouTube channel of Brainiac75.

In the short film he demonstrates how to measure Earth’s magnetic field strength and orientation with the instrument’s sensitive 3-axis probe, proving how much easier it is to do so without using a compass, magnets or a protractor – you need to watch from the beginning to see this bit.

Brainiac75 features a lot of magnet/magnetism related material on his channel, so it’s well worth a look. It may get stuck on you, as we were quite drawn to it!

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!

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.

 

 


New fibre-optic Test and Measurement equipment from EXFO

FTB-5235 Optical Spectrum Analyser
EXFO LogoThe new FTB-5235 Optical Spectrum Analyser from EXFO is a compact, entry-level optical spectrum analyser (OSA) ideal for a variety of field applications, including DWDM and CWDM network commissioning and troubleshooting.

With the largest screen in the industry, and an intuitive user interface, the FTB-5235 offers power and wavelength measurements, has a WDM and drift mode, is capable of OSNR testing (IEC 61280-2-9) and also offline post-processing.

PPM-350D PON Power Meter
EXFO’s new PPM-350D has been designed to fulfil the field technicians need to know what’s what. As communications service providers (CSPs) deploy next-gen technologies onto legacy passive optical networks (PON), by overlaying new wavelengths on existing lines, it is necessary to quickly determine what’s being squirted down a fibre. The PPM-350D PON Power Meter automatically detects the PON technology in use and adapts its test parameters to match.

The PPM-350D is compatible with GPON and EPON, can handle single- and multi-layer PON, has a pass-through mode for ONT/ONU verification, and supports 10G. It also comes with a smart App, Bluetooth and USB.

OSICS Multifunction Test Platform
EXFO has rebadged OSICS multifunction modular platform following its recent acquisition of Yenista Optics. The instrument has the widest selection of plug-in modules, making it the most flexible platform for DWDM (Dense Wavelength-Division Multiplexing) system evaluation and fibre optic component testing.

Up to 8 modules can be mixed and matched in a single OSICS mainframe. The range includes: compact tuneable lasers, a compact transmission laser, broadband light sources, and passive optical functions such as high-power optical attenuators and variable back reflectors.

Please contact us for more information about these or other test and measurement instruments from EXFO.
