 | Portable Vibration Meter
The new HS-620 portable vibration meter from Hansford Sensors has been designed for use both as a simple vibration level meter, or for maintenance engineers across all types of industries. The kit consists of an internal battery operated meter, a hand held probe, magnetic mount, a carrying case and battery chargers for both mains and in-car use. The vibration meter is microprocessor based and by selection of the controls can easily be set up to monitor acceleration (g) levels, velocity (mm/sec), displacement (microns) and bearing condition.

|  | New Strain Gauges
TML have just published a new strain gauge catalogue that includes details on several new products. Of particular interest should be the new YUF strain gauges that have a strain limit for post yield work up to 20 to 30%, but there is also a new cryogenic gauge (CEF) that can be used not only at –269degC, but also up to +200degC. Available in 2mm or 5mm gauge lengths, the YUFLA series is not applicable to the measurement of repeated strain measurements and should be used with TML’s cyanoacrylate adhesive. However when correctly fitted this gauge should be capable of post yield measurements up to 30% strain levels. The CEFLA series of gauges cannot only be used at cryogenic temperatures, but also up to 200degC. This series is available in 1, 3 and 6mm gauge lengths.

|  | High Temperature Accelerometers
Dytran have recently been expanding their line of ultra high temperature accelerometers, designed for vibration testing under extreme temperatures. All designs are charge output types with some having a differential output, although the model 5334 comes with an in-line miniature differential charge amplifier creating a system that will operate from a standard IEPE 2-wire constant current supply. Whilst there have been designs for some time that can be used up to 260degC, new crystal technologies has enabled accelerometers to be designed for use in temperatures up to 482degC, with even higher temperature models being planned.

|  | Bearing Temperature Sensors
Conax have recently produced a data sheet to describe their range of miniature bearing temperature sensors. These sensors are designed to measure the temperature of a bearing beneath the shoe, and if required can also be supplied with sensor wire seals to prevent oil leakage along the wires. The Conax MBS series is available as either Platinum resistance (RTD’s) or various standard thermocouple sensors, and come in five different sizes and designs. Some of the designs are also available with dual sensor elements, and various case materials can be supplied, including stainless steel and brass.

|  | 100kHz Wireless Node
The new HS-Link wireless node from MicroStrain is the latest in their series of wireless sensor nodes for strain gauge and voltage output sensors. A maximum sample rate of up to 100kHz is possible as burst data, which is stored in an internal memory. Either 3 full differential inputs with optional bridge completion or 3 single ended 0-3V inputs can be ordered. The node is designed to log data to internal memory, and upload this data wirelessly to a host computer once logging is complete. Data is collected during periodic, user definable sampling sessions, at rates up to 100kHz.

|  | Ultra-mini Triaxial Accelerometer
The ultra miniature triaxial accelerometer series 3133A, weighs in at just 0.8 grams, and comes in a 6mm cube with integral cable. This sensor will be available in sensitivities of 2mV/g, 5mV/g and 10mV/g and is for adhesive mounting only for minimal mass loading. Even though the 3133A sensors are tiny, they have a robust construction with a welded titanium housing and an integral cable that is epoxy sealed.

|  | SG-Link OEM
MicroStrain are now offering their proven SG-Link wireless circuit on a small PCB for applications where space is tight. The standard design is on a 30mm square board, having one differential channel that includes full strain gauge conditioning with programmable gain and offset, and one single ended voltage input channel. Other OEM custom configurations are available.

|  | Rugged Dynamic Pressure
Dytran have just released their new rugged design dynamic piezoelectric pressure transducer. The model 2006V2 has a 50mV/g sensitivity giving a dynamic pressure range of 100psi. It differs from their other pressure sensors, in that it has a rugged 2-pin MIL-C-5015 connector, and a ¼-28 NPT mounting thread. There will be two other models in this series, with model 2006V3 having a 50psi range, and model 2006V1 having a 500psi range.

|  | Multi-element Seals
New from Techni measure is the Conax range of pressure and vacuum seal fittings, offering a wide choice for sealing single or multi-element conductors or wires. Compression seal fittings restrain the elements from moving as a result of pressure differentials, prohibit the leakage of gas/liquid media along the elements, and can electrically isolate the elements from the mounting device.

|  | Miniature AHRS
The new 3DM-GX3 series of miniature Attitude Heading Reference System (AHRS) sensors, starts with the introduction of the 3DM-GX3-25, which incorporates triaxial accelerometers, gyros and magnetometers. Future models will offer other sensor grades, a more basic inertia measurement unit, and a unit with GPS incorporated. This unit has a USB or RS232 interface as standard.
