DJB Instruments claims breakthrough in high temperature voltage accelerometer technology
DJB Instruments claims that a further increase to 225°C will be announced shortly and that tests in challenging high temperature environments will become easier, cheaper and more reliable. The product has a wide range of applications and engineers working in industries such as oil and gas, energy, aviation, aerospace, automotive and communications will find the versatility the industrial accelerometers provide invaluable.
Paul Hunter, Managing Director, DJB Instruments (UK) Ltd, said: “We’re confident this device will make a big difference to engineers where they are faced with the challenges of collecting data from high temperature environments. This is a step change in what is now possible. DJB Instruments is proud to have made this contribution which is a reflection of our commitment to developing niche products and our ambitions for future growth.”
Up until now, conventional voltage accelerometer electronics have operated within a traditional limit of 125°C which places severe limitations when working within challenging environments.
Working to a DJB Instruments design, the migration of the traditional low temperature control electronics to a high temperature SOI based ASIC device has been carried out by GE Aviation Systems. The control device has been assembled using high temperature electronics packaging technology with piezo-electric accelerometers.
DJB Instruments is pursuing a course of continuous research and development in pressure and vibration measuring equipment. The first release of the new high temperature voltage accelerometer is at a product tested 185°C. Currently DJB Instruments is conducting continuous operation tests on materials which have to be carefully sourced to match the already temperature proven ASIC device. On completion of the company’s next batch of testing DJB Instruments will make available voltage accelerometers rated at 225°C.
