The AR100 is one of the smallest laser displacement sensors in the world. The ultra-compact AR100 comes with ranges from 10mm (0.4 in.) to 500mm (19.7 in.) with a single case size. It can take 9,400 measurements per second and has a linearity of ± 0.05% of the full measurement
The SomatXR MX471-R CAN bus module allows the simultaneous integration of up to four CAN networks into the SomatXR data acquisition system. This module is the more rugged version of the QuantumX MX471 and is ideal for use in extremely tough conditions, such as vehicle tests in the field and
CAN bus Module for Easy Integration of up to 4 CAN Networks The QuantumX MX471 CAN bus module allows the simultaneous integration of up to four CAN networks into the QuantumX data acquisition system and can be expanded as required. The module, combined with analog measurement modules, is ideally suited
TFX-5000 ultrasonic clamp-on meters are quickly and easily installed without cutting or tapping the pipe. Ultrasonic waves transmit upstream and downstream through the pipe wall and water flowing in the pipes. By measuring the difference in the travel time and knowing the pipe size, the meter determines the velocity and flow
Compatible with the entire range of Brüel & Kjær modal exciters, this unit serves two different purposes depending on which exciter is connected. When paired with Type 4827 or 4828, the unit provides variable stiffness to the armature suspension and correctly centres the armature in relation to both the exciter’s
The most powerful of our modal exciters, Types 4827 and 4828 offer precise and reliable operation in any modal testing scenario, including long-duration tests of outsized mechanical structures as well as applications with MISO and MISO configurations.
