The ICA amplifier is our favourite small strain gauge amplifier. With its small overall size of 19.5mm diameter and 7.6mm height and variety of analogue output options including 0-5Vdc / 0-10Vdc / +/-10Vdc and 4-20mA it is a truly flexible device. These features coupled with superb long-term reliability make the ICA amplifier a priceless addition to any strain gauge-based sensor or system. With a <±0.02% non-linearity and the ability to operate in temperatures from -40ºC to +85ºC the ICA amplifier is a truly versatile little unit. We often use the ICA as a small in-line amplifier mounted on the the transducer’s connecting cable. It is housed in a specially-modified IP65-rated diecast enclosure for protection, providing a quick and low cost […]

Rotary Wireless Torque Transducers Use Battery-Powered 2.4GHz Telemetry
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 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 […]
Digiforce Strikes A Chord at Bison Concrete
Bison is the UK’s leading producer of structural, precast concrete products. Consistent, quality control is vital to maintain the company’s position at the forefront of the sector. Bison is particularly renowned for prestressed elements, including hollow-core floors, solid composite floors and beams. Integral to the durability and structural performance of these products is the correct tensioning of the prestressing steel tendons. There are approximately 30 tendons in the average 1200mm-wide hollow-core floor slab. These may be up to 160m in length. The tendon carrier precedes the casting hopper. It lifts the tendons to the required depth in the slab so that sufficient concrete cover is achieved during casting. The tensioning equipment must be tested on a regular basis, but current methods […]
TR200 Portable Battery-Powered Strain Gauge Digital Indicator Launched
Applied Measurements are introducing their model TR200 portable battery powered strain gauge digital indicator. This compact instrument is designed to read outputs from load cells, pressure transducers and most other strain gauge sensors with a full bridge configuration and output sensitivity between 0.75mV/V and 7.5mV/V. Bridge resistances as low as 85 ohms are compatible with the TR200. This versatile instrument which is sealed to IP65, making it ideally suited to a wide range of applications in the automotive, process control, water, aerospace and marine offshore industries where short term measurements are required. The TR200 is particularly suited to on board vehicle datalogging. All adjustments are entered via the sealed key pad to enable the user to set zero, scaling, decimal […]
