Applied Measurements are proud to introduce the DTDR-F rotary wireless torque transducer, a novel design that expunges stator coils and inductive transmission systems from the design brief in favour of a cutting edge, battery-powered 2.4GHz wireless telemetry data acquisition and transmission system. The DTDR-F design is based on the DTD-F torque transducer, a flanged device designed for use in static and quasi-static torque measurement applications, with modifications to allow the incorporation of a pair of balanced Delrin housings, one containing the telemetry acquisition and transmission module and the other containing a 3.6V high capacity lithium-ion (Li-Ion) battery that is recharged in-situ. The DTDR-F is intended primarily for use in rotating applications at speeds of up 6500rpm where a direct, in-line […]

New Stress Analysis Services for Structural Testing
Having built their first transducer in 1991, Applied Measurements of Reading now offer an ISO 9001 compliant stress analysis service to compliment existing in-house manufacturing of strain gauge based sensors for the measurement of load, force, pressure, torque and linear displacement. Increasingly measurements are required on parts that either cannot be moved or the application is for research and long term monitoring is required. This might include bonding of strain gauges directly to components, structures or machines. The service can be tuned to suit specific customer requirements that may include installation and calibration only, design of bespoke transducers to run a test or full installation, testing and reporting on completion. Applied Measurements can accommodate all measurement parameters including short as […]
New Wireless Telemetry Systems For Strain Gauge Sensors
For years the demands placed on higher performance measurement systems have meant they are often less versatile than their predecessor. More sensors means more data is acquired over an increasing number of measurement channels and with these advances has come corresponding concerns regarding cable integrity and management. This places emphasis on the test technician who is well used to swapping between sensors and matching them with the cable of the right length and appropriate connector. Running cables across floors or through sensitive areas is at best inconvenient; with high performance cable products subject to mechanical damage throughout routine use. Considered the weak link of many a measurement system, they are often the first focus of attention whenever measurement errors do […]
High Accuracy Displacement Sensors Use Strain Gauge Technology
As a result of increased demand from customers preferring to use a strain gauge based measuring system, we have introduced a 0–100mm version to our range of AML/SGD high accuracy displacement transducers. Based on a four-arm Wheatstone-Bridge design with a nominal impedance of 350 Ohms, the design ensures excellent non-linearity, low power consumption and excellent temperature stability. Additionally, the characteristics of strain gauge based sensors provide higher accuracy linear sensing than that of less accurate and lower resolution LVDT sensors. These advantages of our AML/SGD high accuracy displacement sensors have been realised by Oxfordshire based company Fugro GeoConsulting Limited, who use the existing 0-50mm version of the sensors within their accredited geotechnical soil-testing laboratory. This high-tech establishment tests soil samples […]
Bolt-On Weighing Systems
Fitting a weighing system to an existing silo, hopper or tank using a conventional load cell system can be expensive, disruptive and sometimes even impossible. UK sensor experts Applied Measurements Ltd offer a solution to these problems by using a simple bolt-on load transducer. This weighing approach is cost-effective and quick to install, causes a minimum of production downtime and is ideal as a retrofitted system. The BOSS bolt-on sensor is a well-proven robust product consisting of a strain-gauged element encased in a protective housing. It is simply bolted to a structural member of the silo and deflects under the changing weight conditions, to give a varying electrical output relative to the load. Bob Davies, general manager at Applied Measurements […]
Custom Torque Sensors Now Available on Standard Lead Times
A UK manufacturer of torque sensors is offering custom designed static/reaction torque transducers on similar lead times to its standard units, with only a small premium on the standard list price. Applied Measurements Ltd, based in Aldermaston, is able to design and manufacture custom torque sensors to meet any customer requirement, including different flange diameters, unusual sizes of square drive, special sealed versions and shorter, more compact designs. According to Peter Lewis, Managing Director at Applied Measurements: “Many manufactured products require fatigue testing to ensure that they can operate for a guaranteed minimum period of time. An accelerated life test, for example, may be carried out on a drive shaft to determine the torque limits. The fatigue testing can sometimes […]
New Range of Strain Gauge Based Displacement Transducers
Applied Measurements is pleased to announce the introduction of a new range of strain gauge based displacement transducers, the AML/SGD Series. It is now available with stroke lengths of 0-5mm, 0-10mm, 0-25mm and 0-50mm. The accuracy offered is +/-0.1% up to 25mm and +/-0.15% above 25mm, plus excellent long term and thermal stability. They require a stabilised dc voltage excitation anywhere between 2 and 10 volts and return a high level millivolt signal proportional to the position of the plunger. The AML/SGD Series are constructed using a rugged stainless steel tubular housing containing a spindle guide bearing and spring return mechanism. A light spring force ensures a minimal effect on the application and enables inverted operation when required. Precision construction […]
Underwater Load Cell offers Tension and Compression Measurement
When approached by one of our customers to design a load cell for underwater tension measurement, We looked at our core range of products and decided the DDE style load cell, which features M12x1.75 male threads at each end, would best meet the customer’s requirement, but this model as standard is only rated to IP65. With a small, quick and cost effective re-design we changed the construction to Stainless Steel with two halves locking together with a seal. Internally it was further protected by back-filling with an inert waterproof gel. The electrical termination is a tough IP68 multicore cable that is connected through an IP68 cable gland, to complete fully submersible sealing. The new underwater load cell has been designated […]
