Vibrating wire gauges & their use in Civil Engineering Kevin on vibrating wire gauges An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd They were the very first strain gauges, take a wire, pull it across and pluck it. Vibes at a frequency. If pull the ends apart and do the […]
The different methods for measuring various force types Kevin on the ways of measuring different forces, torque, pressure, bending moment. An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd Lets just look at modes in a load cell, can use axial, have a straight forward column, put strain gauges on, so […]
All about crack detection and crack propagation sensors Kevin on Crack detection and crack propagation sensors, and the differences between them An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd Crack detection and crack propagation sensors are two different things So crack detection Say you’ve got an aircraft structure and you’ve […]
Why cryogenic installations are so special Kevin on cryogenic load cells An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd Sensor Solutions: ‘So tell me about cryogenic load cells, is just the bonding problems that you have?’ No with cryogenic, there’s a couple of things, down at cryogenic temperatures you get […]
The difficulties involved in high temperature installations Kevin on very high temperature load cell installations An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd Sensor Solutions: ‘So what’s the difference between cryogenic and very high temperature work?’ At high temperatures everything becomes like chewing gum. Above about 460 degrees C, all […]
How multi-axis load cells and sting balances work The relationship between sting balances and multi-axis transducers An Interview with Kevin Copleston, one of the founders of Sensor Solutions Ltd Sensor Solutions: ‘So a multi-axis load cell is really?’ Right well, it depends. I’ll make a simple 3 axis to show what you want. Here’s a […]
Automotive crash test: How to solve the problem of measuring tension load Force Sensing bolts, an innovative solution Sensor Solutions was approached with a problem of measuring tension load in a batch of miniature bolts for an automotive crash test. A small hole was drilled into each of the bolts and a full bridge measuring […]
What is signal conditioning? Why is it used in data acquisition and data logging? A strain gauge on its own does not transmit any form of signal, it that merely has a resistance in its circuit, which varies as the gauge is distorted when the object to which it is bonded is placed under stress […]
Prototype development We have recently worked with an Aerospace manufacturer on a specialist project; a strain gauge installation for structural monitoring and integrity testing of a prototype aerofoil component, an outboard flap. The manufacturer had a proposed design for a new upgraded flap, but before it could get anywhere near being placed in production for […]
Strain analysis pin-points potential cause of window de-laminations in service. A client was experiencing premature de-lamination of a production window that was subject to pressure cycles in service. Determining the cause We advised the client of a strain gauge based solution to determine whether the de-lamination was being caused by higher strains than the Finite […]
