Weigland Wire Energy Harvesting components

POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries.

The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. a nearby permanent magnet mounted on a rotating shaft) the Wiegand wire will initially retain its original magnetic polarity, and then abruptly ‘flip’ its polarity when the change to the external magnetic field reaches a certain threshold. This sudden change in the magnetic state of the core induces a current pulse in a copper coil wound around the Vicalloy core. This current pulse is very short-lived, but the energy harvested from the mechanical movement of the magnet can be captured and used to activate a low-power electronic circuit. An important feature of the Wiegand effect
is that the amount of electric power generated with each reversal of the magnetic polarization is constant and completely independent of the rate of change of the external magnetic field, even if this happens very slowly. POSITAL Wiegand modules have been used to reliably power rotation counters in tens of millions of devices, including multi-turn rotary encoders, gas and water meters.

Wireless Tilt Systems

Sherborne Wireless Tilt Sensor.  Phone for pricing.Sherborne Sensors Wireless Tilt System (WTS) is designed to provide surveyors, geotechnical specialists and structural engineers with a complete measurement solution, without the cost, impracticality and system installation times of traditional wired methods. The WTS is a flexible, all weather, radio telemetry system that delivers highly accurate, remote angle, measurement data.

The WTS uses an advanced MEMS sensor to ensure high accuracy and maximum reliability. The multi-channel and distortion-free digital two-way telemetry system has a wireless range of up to 330ft (100m), 18 bit resolution and long battery life. Its robust design will ensure precision operation over many years in the most demanding environments.

Highway agencies, bridge and civil structure owners spend large revenues assessing structural health by visual or other types of consuming inspection methods of bolted and welded joints, together with other vital structural elements. Obtaining multiple readings to monitoring the entire structure can be costly and labour intensive. Using the WTS Wireless Tilt System, a single structure can be fitted with low power WTS Inclinometers at strategic points, thus helping to determine where weak points may be and when maintenance is required.

Furthermore, the WTS can be used to verify design calculations during the manufacture of new structures, providing valuable data for refining computer aided modelling of structural behaviour. A variety of complementary base stations and PC or hand-held data acquisition modules are available to deliver a complete measurement solution configurable to any type of structural health monitoring application. Contact us to find out more about how the WTS can support your business.

A320 low range accelerometers  Details phone Hassan 09 630 7871The A320 Series and A320L Series are high precision, servo balance ultra-low range accelerometers available in single and multi-axis configurations. They can be used in commercial, industrial, military and aerospace applications – from geophysical, seismic and civil engineering studies, to flight test monitoring and low acceleration analysis.

Individual models are available down to ±0.1g full scale, with full range outputs of ±5Vdc or 4 to 20mA. Despite their low measuring range, the A320 and A320L Series sensors are extremely robust and highly resistant to mechanical shock. Sealed to IP65, they are housed in an aluminium corrosion-resistant casing and will withstand 1500g shock events, and operate reliably in temperatures ranging from -18°C to 70°C without significant degradation in performance. Electrical termination options are either a 6-pin, bayonet lock connector, or solder pins.

The A320 Series offers customers the ability to accurately measure ultra-low g events with a device that upholds the same high levels of performance and robustness as other Sherborne Sensor products. It complements our current accelerometer product line, and was developed as a standard product offering in response to customer demand.
