Product Features
- Piezo film sensors (high sensitivity, AC coupled, laminated, robust)
- If the dimensions of the assembly are deformed by direct deformation, the device acts as a flexible "switch", and the generated output is sufficient to directly control MOSFET or CMOS stages. If the assembly is supported by its contacts and allowed to vibrate in the open space (with the inertia of the clamped/free bar creating bending stress), the device behaves like an acceleration or vibration sensor.
- By adding ground or changing the free length of the element by clamping, the resonant frequency and sensitivity of the sensor can be adapted to specific applications. A multi-axis response can be achieved by an off-centre positioning of the mass.
- The LDT0-028K is a flexible component made from a 28 m thick piezoelectric PVDF polymer film with screen printed ink electrodes laminated to a 0.125 mm thick polyester substrate and fitted with crimp contacts. Due to the displacement of the piezo film from the mechanical neutral axis, bending creates very high stresses in the piezo polymer and thus high voltages.
- The LDTM-028K is a vibration sensor in which the sensor element consists of a boom loaded by an additional mass to provide high sensitivity at low frequencies.
