Feature: T&M
natural energy is available from sun or wind, it makes sense to harness that power. For example, a weather station could use a secondary (rechargeable) battery that is charged by solar or wind power and hence operate for many years without the need for human intervention. Whilst some devices have the luxury of being able to
scavenge renewable energy, others like ocean-bottom seismometers can be set for long periods in remote locations where they have limited or no access to power and cannot be recharged or replaced. In these environments, primary (non-rechargeable) batteries with low self-discharge rates are essential to provide power across a period spanning several weeks or months. The batteries will also need to be ruggedised to withstand high pressures and shock.
Challenges in T&M applications Although each of the above applications are varied and require different forms of power, what they have in common is the need for reliable, high-performance batteries. If the batteries were suddenly to fail, then there would be no readings available, hindering, possibly fatally, the research or monitoring purposes of the devices. One of the core challenges faced by batteries in test and
If batteries were suddenly to fail, then there would be no readings available, hindering the research or monitoring purposes of the devices
measurement systems is that there’s no single set of typical problems. A portable vehicle-emissions-testing device will face very different operating environments from a seismometer. For this reason design engineers on test and instrumentation
projects should work closely with battery suppliers, which may lead to bespoke smart batteries that meet an application’s unique challenges. With years of experience developing and manufacturing
smart batteries to meet the complex requirements of many test environments, Accutronics can develop a battery that delivers reliable power and provides leading functionality. Te company’s Accupro bespoke service builds on this experience to design, develop and manufacture a custom battery or charger that meets the application requirements and product development timeline. If we consider science and engineering as our way of observing
the fundamentals of the world around us, accurate measurement is how we determine what those fundamentals are. High-quality components, including batteries, are essential to ensure that measurements are, and continue to be, accurate.
