MicroStrain offers a range of miniature displacement sensors.  These include contact sensors, non-contact sensors, and signal conditioners. Within our contact sensors, we offer gauging, non-gauging, sub-miniature (very small) and micro-miniature (smallest available on the market) displacement sensor designs.  MicroStrain displacement/position sensors are known as DVRTs (Differential Variable Reluctance Transducers) which are half-bridge LVDTs (Linear Variable Differential Transformers).  Our DVRTs deliver a very high linear stroke range to body length ratio, and can be used in environments where traditional LVDTs are too large.  MicroStrain’s miniature displacement transducers are extremely robust, capable of operating at temperatures up to 175°C in corrosive media such as saline, oil, and brake fluid.  The near frictionless design enables sensors to operate over millions of cycles without wear or degradation in signal quality.

MicroStrain’s displacement sensing products including transducers, signal conditioners, and motherboards. These systems provide highly precise measurement solutions. MicroStrain’s contact displacement transducers deliver highly precise linear measurements with an extremely small, miniature design.  Both gauging and non-gauging displacement transducers are available. Our non-contact displacement transducers are designed to measure the displacement and proximity of a metal target without physical contact. MicroStrain offers wireless, analog, and digital output DVRT signal conditioners. Signal conditioners are required for use with MicroStrain DVRT displacement sensors.   .familyNav1, .familyNav2, .familyNav3, .familyNav4 { background: none repeat scroll 0 0 #CCCCCC; color: #FFFFFF; display: block; font-size: 14px; margin: 1px 0; padding: 6px 0 3px 6px; text-decoration: none; } .familyNav1:hover, .familyNav2:hover, .familyNav3:hover, .familyNav4:hover { opacity:1.0; filter:alpha(opacity=100); } .familyNav1:hover, .familyNav1.live { background:#0468AD; } .familyNav2:hover, .familyNav2.live{ background:#32641E; } .familyNav3:hover, .familyNav3.live{ background:#B55A11; } .familyNav4:hover, .familyNav4.live{ background:#76285D; } .familySub { margin: -1px 0 0; opacity:0.7; filter:alpha(opacity=80); font-size:12px; } .familySub img { width: 22px; } WIRELESS SENSOR NETWORKS

Bending the fiber in one direction leads to a better transmission whereas bending in the other direction leads to a lower transmission, compared to the straight position.

Plastic optical fiber can also be used for seat-occupancy recognition

One approach for seat-occupancy recognition is the Kinotex cavity sensor from Canpolar East (St. John’s, NF, Canada).

Please note that the period to apply for Canada Summer Jobs 2014 will be from December 2, 2013 to January 10, 2014

Jobs funded under CSJ must be from six to sixteen weeks in duration.

Plastic can be as glossy as glass but, unlike glass, it is hydrophobic – it repels water. If water does not flow smoothly over the surface, the mirroring chemicals will not deposit evenly. There are two ways to overcome this problem: You can flood the surface with so much water (or mirroring chemicals) that the beads merge into a smooth sheet. This technique works best using our mirror bath technique where the object to be mirrored is submerged in the chemicals. It is only practical for small objects. You can use a wetting agent (a type of surfactant) to break the surface tension on the plastic before you apply the mirroring chemicals. There are many types of plastic and each type has its own chemistry and surface characteristics. We have tested our Wetting Agent on some types of acrylic, polycarbonate and polyurethane. We have not tested it on all types of plastic. You should test it on a sample of your substrate to confirm that it works. See Cleaning and Polishing for more information on wetting agents.
