Lockheed Martin has established a new measurement center and upgraded its force measurement department to the highest standards. Among the most important instruments in the new test centre are the TOP transfer force transducers and HBK precision amplifiers.
Among the most important instruments in the new measurement center are the TOP transfer force transducers and the DMP40 precision amplifier from HBK. The TOP transfer force transducers are already in use in the national metrological institutes of Europe and are 10-times more accurate than the previous best force transducers according to ISO 376 Class 00. They were developed for applications at the top of the calibration pyramid, for comparisons between national calibration laboratories.
The laboratory accepts and calibrates force transducers from more than 100 Lockheed-Martin facilities worldwide and also provides this service for other companies.
The LMIMC uses two Morehouse force presses to perform the calibrations. The two presses and all the reference transducers from HBK are designed both for tensile force and compressive force testing. The relevant analog measurement signals arrive at HBK’s DMP40 precision amplifier, which outputs the measured values at an accuracy of 0.0005 % and a resolution of 2,000,000 digits.
Some of the force transducers to be calibrated fit in the palm of your hand, others weigh almost 230 kg. The nominal loads are between a few grams and several tons.
It is quick and easy to switch between test piece capacities, asthe measuring amplifier can be programmed for eight load ranges and has the HBK catman® measurement software available.
Although HBK’s TOP force transducers are new to the American market, they have been in use for many years as reference standards in national metrological institutes in Europe and for international force comparison measurements. Their repeatability is ten times more precise than is required under ISO 376, making their accuracy better than Class 00. The expected long-term stability, with a variation of less than 0.002% per year is also outstanding.
The DMP40 is used worldwide in national metrological institutes as the test standard.
The company specialises in defence technology, solving complex challenges, advancing scientific discovery and delivering innovative solutions that help our customers keep people safe.
As unidades de calibração de ponte HBK, como a BN1000A, são calibradores de alta precisão para calibrar equipamentos de medição e cadeias de medição, que atuam como uma unidade de calibração de alta precisão para instrumentos de medição.
