DJB designs, manufactures, assembles, tests and calibrates every part of theirproducts all in-house. They export all over the world via a network of distributors.
They have been a British leader and manufacturer for over 40 years, proudly achieving a substantial range of quality accelerometers and vibration testing equipment whilst maintaining the unique Konic Shear design introduced by the company’s founder Don Birchall to better aid your needs. They all have a care for the work they do at DJB, proud of its history and keen for its future. This is reflected in the products they have available and the services provided to support you in your testing needs all the way through your process. The company’s main focus is to manufacture piezoelectric accelerometers (IEPE and Charge), dynamic pressure transducers and analogue signal processing instrumentation for engineers working in the areas stated below.
DJB's range of accelerometers are available in a variety of configurations, we produce both Charge Output and Voltage Output IEPE Accelerometers including the worlds smallest stainless steel accelerometers (A/28/E and A/128/V) and modal clip mounted triaxial accelerometers (AT/11, AT/13, A/136). Our range also includes unique and industry leading water cooled IEPE accelerometers capable of operating in extreme temperatures ranging up to 900°C.
DJB's wide range of accelerometers are suitable for almost any vibration measurement application requiring a high degree of accuracy, in a potentially hostile environment.
Charge or IEPE – If you are using a charge accelerometer you will need a charge amplifier. Very few data acquisition systems offer built in charge conditioning so an external box will be required. IEPE accelerometers can often be connected directly to the acquisition system as the IEPE power is available, an ideal way of minimising hardware needs. If an older acquisition system is used, a range of IEPE signal conditioners is available from battery powered/DC supplied to rack Base multi channel solutions.
In line Charge Amplifier – This is becoming a very popular way of connecting charge accelerometers, utilising the IEPE power built into many data acquisition systems. The fixed gain amplifier is housed in a BNC/microdot adaptor, allowing it to be connected directly to the data acquisition hardware with a low noise cable attached to a charge accelerometer.
Filters – Analogue filters enable users to filter out unwanted noise or other spurious signals.
Integrators – Conversion of the accelerometer signal to either a velocity or displacement value is a relatively simple mathematical process. Integrators can do this in real time allowing the use of the already converted signal. DJB Instrumentation is available as modular systems in portable case or rack based systems as well as fixed, single or 9 channel solutions.
DJB Instruments UK Ltd offers the widest range of assembled stock cables for accelerometers, for same day despatch and with more than 15,000 connectors and 40 different cable types available in stock we can also assemble cables to suit the customer requirements.
