EMD provides the best in component supply, anti-counterfeit mitigation, logistical solutions and new-design support, primarily for the high reliability market sector. We are proud to deliver what EU companies are best known for, Quality and Service. Our activities are shaped by our customers, whether that is shielding you from the threat of counterfeit components, working with your design teams to introduce the latest in cutting edge technology or through life support programs for legacy products.
We supply acceleration sensors for the most important industrial applications and industries.
The uni-axial and tri-axial acceleration sensors work daily in high-precision devices to measure vibration, shock pulse, speed, distance and inclination. With the help of DC response silicon MEMS (Micro Electro Mechanical Systems) and piezoelectric film / ceramic techniques, we deliver high quality products. The acceleration sensors are known for their powerful and stable silicon chips.
Areas of application:
Alarm, crash test, transport monitoring, laboratory applications, medical technology, vibration monitoring of high-quality machines and devices, robotic, vibration analysis, artificial gyros, and much more
Silicon Design Chips
We supply acceleration sensors from single-axis sensor elements in SMD design to three-axis sensors with and without integrated amplifier electronics .
In addition, we assemble the sensors customer-specifically with housing, cable and connector.
Piezoresistive: monolithic made of silicon (bridge) from frequency "zero" to approx. 2000Hz.
Capacitive: for a working frequency from "zero" to approx. 2500Hz.
Alarm, crash test, transport monitoring, vibration monitoring of high-quality machines and parts, robotic, vibration analysis, artificial gyros, and much more
Silicon Design 1-axis
Description model 2210
The model 2210 acceleration sensor module combines an integrated model 1521 with low-resistance buffering for acceleration measurements in commercial and industrial plants. The anodized aluminum housing is sealed with epoxy resin and can be easily mounted using two M4 (or M3) screws. It is relatively insensitive to temperature fluctuations and gradients.
Description model 2240
The Model 2240 is a hermetically sealed version of the Model 2220. This robust module combines an integrated SDI low-noise acceleration measurement and a low-resistance buffering for acceleration measurements in trade and industry.
Measuring ranges model 2210 and model 2240: +/- 2 g ... +/- 400 g
Silicon Design 3-axis
Description model 2466
The Model 2466 is a three-axis version of the popular Model 2266 (1-axis).
This acceleration sensor is located in a robust housing, for measuring accelerations in commercial and industrial plants. Its anodized aluminum housing is sealed with epoxy resin and is easy to assemble using two M8 (or M4) screws. It is relatively insensitive to temperature fluctuations and gradients.
Description model 2480
The Model 2480 is a hermetically sealed version of the Model 2470. This robust module combines three integrated SDI low-noise acceleration sensors with low-resistance buffering for measurement acceleration. The titanium case is sealed with a laser welding process and easy to mount using two M4 (or M3) screws.
Measuring ranges model 2466: +/- 2 g ... +/- 400 g
Measuring ranges model 2480: +/- 2 g ... +/- 200 g
Tests of platinum resistance thermometers and other sensors according to IEC 60751 or DIN EN 60751
Insulation test at room temperature
The insulation resistance between the valve and each measuring circuit must be measured with a test voltage of at least 100 V DC. The insulation resistance must not be less than 100 MΩ.
High voltage test
A test voltage of 500 V AC must be applied between the armature of the sensor and each measuring circuit. No short circuit may occur within the test time (min. 60 s). If the thermometer passes this test without a short circuit, the measurement is passed.
The transportation system lies at the backbone of the modern world, with the railway system being its most crucial component. As such, progress in this field has determined more and more high-tech sensors to be incorporated into trains and the infrastructure of the railways in order to ensure a proper evolution of this means of transportation. Not only do these sensors monitor the status of the trains and tracks, guide and control the train, facilitate repair planning and reduce maintenance costs, but they are also meant at improving aspects relating to passenger safety and comfort. Accelerometers represent a large part of these sensors and they are used to monitor several types of mechanical motions such as inertial force (acceleration), tilt (inclination), vibration and shock. We stock and distribute MEMS based capacitive sensors, with attractive characteristics of size, power, reliability, long-term bias repeatability, signal to noise ratio and robustness. By combining integrated circuit processing with specific MEMS processes, we produce microscopic mechanical structures fit for today’s evolving field of railway transportation.
