Strain Checker

TML have introduced another new design of holder for their frictional strain gauges. The new FGMH-1B and FGMH2A are designed for metallic targets, since a magnet holds the Strain Checker to the structure whilst a spring holds down the integral frictional gauge to the surface.
Whilst ordinary strain gauges measure strain generated in a structure through adhesive mounting, the frictional strain gauge measures the strain by the friction produced at the interface. Strain is easily and immediately measured by directly attaching the strain checker to a position of interest, using the arm at the top for aligning the gauge. The FGMH-1B is a standard type strain checker, being small and light, whereas the FGMH-2A, which uses a smaller 3mm gauge, is designed for applications in a narrow space.

Inertial Module for Position

MicroStrain have released the third in their new series of GX3 Inertial Measurement Systems. The 3DM-GX3-45 high-performance, miniature system combines MEMS inertial sensors, a highly-sensitive GPS receiver, and a complex Extended Kalman Filter to generate optimal position, velocity, and attitude (PVA) estimates.
This combination of technologies creates better short-term GPS-out performance, sustained-G attitude performance, and provides higher rate PVA data than typical GPS and AHRS Sensors. Raw GPS data, IMU data, and filtered INS data are time-aligned and available as custom, user-defined packets. The 3DM-GX3-45 offers a range of navigation-related output quantities, including: estimated position, velocity, and attitude; position, velocity, and attitude uncertainties; bias- compensated angular rate, linear acceleration, local gravity magnitude and vector, and local magnetic field declination.

Extended Range V-Link

The 8 channel V-Link has now been added to the new mXRS range of wireless nodes from MicroStrain, that offer a much longer transmission range (up to 1km), as well as excellent synchronisation between multiple nodes, with control from just one of the new WSDA-Base base stations.
At the heart of MicroStrain's extended range synchronized (mXRS) system is the WSDA-Base, which uses exclusive beaconing protocols to synch precision timekeepers embedded within each sensor node in the network. The WSDA-Base also coordinates data collection from all sensor nodes, including now the V-LINK-mXRS. On-board sensor excitation, bridge completion, programmable gains & offsets, and differential & single ended inputs provide an extremely versatile sensor interface.

DC Triaxial Accelerometers

Dytran Instruments has introduced the 7503A series, a family of high precision triaxial MEMS DC accelerometers designed for use in both commercial and military applications. The 7503A series accelerometers combine a micro-machined MEMS capacitive sensing element housed in a hermetically sealed titanium case to deliver reliable performance in harsh conditions.
Tailored for zero-to-medium frequency applications, the Dytran 7503A series combine an integrated variable capacitance accelerometer chip with a high drive, low impedance buffer for low-level acceleration measurements, and they are offered with a choice of seven different sensitivities and available in measurement ranges between 2g and 200g.

Conax Brochures

Conax Technologies offer a wide range of pressure sealing glands and temperature sensors, and apart from their two major catalogues that describe their product range, they also publish several brochures that show some of their more specialised products in more detail.
Among these brochures are details on the range of miniature bearing temperature sensors designed to provide a warning of rising temperature in bearings, so that early signs of breakdown of the lubricating oil film can be recognised. There are also several brochures giving details on special high temperature thermocouple assemblies and exhaust gas sensors.

New Gapman Gen3

Capacitec have introduced an upgraded replacement for their long established Gapman product. The new Gapman Gen3, includes many improvements and additions, yet will be offered at about the same price. One of the most obvious changes is the high brightness, high resolution, active matrix OLED display, which also shows the stored step changes and units. The Gapman Gen3 non-contact design, features a dual capacitive sensor mounted on a thin wand, for easy insertion into very thin gaps down to 0.19mm, with versions measuring up to 3.00mm. There is also a contact type sabre that requires no ground connection, and can be used to measure gaps between any materials.

Miniature Load Cells

TML have introduced to their range of miniature strain gauge load cells, two new transducers with only 2 and 5 Newton full-scale ranges. Having a weight of only 1 grm, these sensors can be used for applications that require small lightweight load measurements. These CLS load cells are 12mm diameter and 4mm high to the top of the load button. They have a 2m integral cable like the rest of the series, which have ranges up to 10kN, and are widely used for measuring load distribution or loads in structural model testing or as a sensor for industrial machinery.

Inertial Module with GPS

MicroStrain have released the second in their new series of GX3 Inertial Measurement Systems. The 3DM-GX3-35, high-performance, miniature AHRS (attitude heading reference system) with GPS, combines MEMS sensor technology and a highly sensitive embedded GPS receiver, for use with an external antenna.
The module incorporates a triaxial accelerometer, triaxial gyro, triaxial magnetometer, temperature sensors, and a dedicated 32-bit processor running a sophisticated fusion algorithm to provide orientation, inertial, and GPS measurements.

Extended Range Wireless

The new mXRS range of wireless nodes from MicroStrain, offer a much longer transmission range (up to 1km), as well as excellent synchronisation between multiple nodes, that can now be controlled from just one of the new WSDA-Base USB base stations. At the heart of MicroStrain's extended range synchronized (mXRS) system is the WSDA-Base, which uses exclusive beaconing protocols to synch precision timekeepers embedded within each sensor node in the network. The WSDA-Base also coordinates data collection from all sensor nodes.

New Bracket Style Accelerometers

Dytran Instruments has recently introduced two new bracket style accelerometers. The model 3302A, a biaxial IEPE accelerometer, and the single axis model 3091A, are designed to provide dynamic vibration monitoring within Active Vibration Control (AVC) applications typically found on commercial and military aircraft.
Utilizing an innovative biaxial design, the model 3302A incorporates the mounting bracket and sensing elements in a single package. The single channel 3091A is similar, with both models offering a measurement range up to 500g, with a 10mV/g sensitivity.
