What is a Strain Gauge and How Do They Work?
Strain gauges are sensors that measure the deformation (strain) of an object when subjected to external forces. A strain gauge typically consists of a thin, flexible backing with a metallic foil, which deforms when the test subject deforms and is used to predict how long an object will perform underRead More
Understanding the Science Behind Pressure Mapping
From biomechanics to manufacturing, pressure mapping is transforming the way we understand and enhance performance. Systems like Tekscan’s I-Scan offer real-time insights into pressure distribution, force, and load balance across surfaces. Whether you’re optimising the comfort of seat designs, improving medical devices, or enhancing the efficiency of industrial seals, thisRead More
TechNote: Charge vs Voltage mode Piezoelectric Sensors
Piezoelectric sensors measure dynamic phenomena such as force, pressure and acceleration (including shock and vibration). Inside the sensor, piezoelectric materials such as quartz or man-made ceramics are stressed in a controlled fashion by the physical input of the specific phenomena to be measured. This stress “squeezes” a quantity of electricalRead More
LXRS & LXRS+ Wireless Protocols
This article will attempt to explain the difference between the LORD Sensing MicroStrain term LXRS and their new LXRS+ wireless communication protocol. Lossless eXtended Range Synchronized is the proprietary LORD Sensing data communications protocol used in their wireless sensor network. It was initially developed in 2013 to support applications includingRead More
New Introduction to Piezo-electric Accelerometers
We would like to draw attention to a publication that we have recently added to the resources section of our web site. This is the Introduction to Piezo-electric Accelerometers that informs readers about the main points of accelerometer design and describes the various specifications that should be considered in choosingRead More
Traceable Accelerometer Calibration at Temperature
Many vibration tests are carried out under the influence of temperature, whereby accelerometers are attached to the vibration exciter and/or to the device under test. These are thus exposed to temperatures which can be far above or below room temperature, which is where the sensors are usually calibrated. Calibration ofRead More
Migrating from GX4 to GX5 Inertial Sensors
The 3DM-GX5 is the latest generation of the LORD MicroStrain 3DM-GX series of IMU, VG, AHRS, and GPS-INS sensors. This is truly a “drop-in” replacement for the previous-generation GX4 inertial sensors, making it extremely simple to upgrade. The GX5 shares the same extended temperature range operation, footprint, rugged aluminium case,Read More
