Accelerometers can be used to measure vibration, shock, velocity, displacement, tilt and inclination. The Vibration Sensors Business Group spearheads Measurement Specialties' global initiative to focus on the accelerometer and vibration sensing business with customers in the automotive, medical, military/aerospace and consumer goods industries. This group builds on Measurement Specialties' Silicon MEMS, Bonded Strain Gage and Piezoelectric sensing technologies. More than any other sensor company, Measurement Specialties can choose the best possible technology to solve customer problems and achieve high performance at very competitive costs.
Piezoresistive Silicon MEMS & Bonded Strain Gage
Measurement Specialties' experience designing Micro-Electro-Mechanical Systems (MEMS) using silicon structures is unsurpassed in the world. We have developed and commercialized several product areas based on silicon micromachining technology, offering an unmatched range of standard products with a strong custom design capability.
Piezo Film & Ceramic
Measurement Specialties innovative approach for cost-effective piezoelectric accelerometer designs resides in its ability to use a broad range of materials including crystals such as quartz or man-made ceramic and polymers that have piezoelectric properties. OEM manufacturers look towards this technology as it provides lower-cost sensors requiring no external power supply.

Measurement Specialties manufactures Schaevitz® AccuStar electronic clinometers and AngleStar electronic protractor systems which use capacitance-based sensors for the precise measurement of level, angle or tilt. These unique, patented designs feature a wide range of performance parameters, interface options and price alternatives. These rugged sensors can withstand high levels of shock and vibration that might destroy a MEMS-type device. They also have very high accuracy, especially around zero degrees, which makes them ideal for leveling applications. Uses include construction equipment, tipover protection, antenna positioning, vehicle testing and car alarms, aerospace and robotics.

Piezoelectric film ultrasound transmitters and receivers offer unique advantages for air ranging applications. Resonance frequency and vertical beam directivity of the transmitter and receiver can easily be customized by changing the diameter and length of the PVDF cylinder. Cylindrical PVDF receivers exhibit very wide horizontal or omni-directional beam directivity and broad band characteristics. These characteristics lend unique solutions in many applications such as two-dimensional positioning, digitizer, object detection, and distance measurement. Piezo film ultrasound transducers also have very low resonance "Q" values. This means that the signal rise and decay times are much shorter than conventional ceramic ultrasound transducers, making Piezo film transducers ideal for positioning applications.

Piezoelectric Film is an enabling transducer technology with unique capabilities. Piezo Film produces voltage in proportional to compressive or tensile mechanical stress or strain, making it an ideal dynamic strain gage. It makes a highly reliable, low-cost vibration sensor, accelerometer or dynamic switch element. Piezo Film is also ideally suited for high fidelity transducers operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz) ranges.

Measurement Specialties manufactures Piezo polymer into a coaxial cable format, where the Piezo polymer is the “dielectric” between the center core and the outer braid. When the cable is compressed or stretched, a charge or voltage is generated proportional to the stress. Continuous lengths of Piezo cable are available in a variety of different gages and construction formats. As a standard product, it is offered as a 20 AWG center core with a polyethylene outer jacket, which is useful for large area sensing applications such as physical security, proximity sensors, traffic sensors and security fence transducers.
Piezo cable has a number of advantages in certain applications. Due to its coaxial design, the cable is self-shielded, allowing its use in a high EMI environment. It is extremely rugged, and will stand up to heavy loads as with truck axle counting. Its linear format makes it ideal for monitoring large areas. Two versions of the Piezo cable are offered: copolymer and spiral wrapped PVDF.

Measuring Mixers
Simulate production realistically on a laboratory scale
Brabender® measuring mixers are interchangeable measuring heads which, in connection with a Plasti-Corder® Lab-Station or Plastograph®, serve for testing the processibility of thermoplastics, thermosets, elastomers, ceramic molding materials, fillers, pigments, and many other plastic and plastifiable materials under practice-oriented conditions, cost-effectively, reliably, with little expenditure of time and material.
The measuring mixers consist of a mixer backstand with gear unit and a detachable mixer bowl. In addition to the electronic safety systems, they are connected to the drive unit through a shear pin coupling protecting both mixer and drive unit from damage due to overload.
