Inelta Sensorsysteme, leading sensor manufacturer for measuring distances, movement and force, has developed valve sensors and position switches based on its LVDT technology and featuring high precision and a rugged design for hydraulic applications.
Inelta LVDT-HY series sensors, for example, with a measuring range between ± 1.2 mm and ±10 mm, provide accuracies in the μm range in detecting valve positions. As a market innovation, Inelta has introduced LVDT-based valve sensors, designated IHDL-M16, where the sensor module can be exchanged without interrupting or opening the hydraulic circuit. Drawing on many years of know-how in research and development and high production capacities, the sensor specialist is capable of producing custom-designed valve sensors for demanding applications in high quantities.
Like the standard product line, custom-designed valve sensors are supplied as incapsulated, turnkey systems, consisting of an LVDT sensor, a pressure tube and a connecting shaft. The systems are available for measuring ranges between 1.2 mm and 36 mm, as versions for installation as an add-on or as integrated sensors. All hydraulic components can withstand 400 bar pressure with max. pressure peaks up to 1,200 bar. Outputs are customer-specified, analog 4…20mA or 0…10V or with digital interfaces such as IO-Link. Upon request, Inelta will design sensors for other applications, such as pumps and dosage systems.
For applications with high vibration and shock, Inelta has developed a sensor capable of handling 30g. The standard protection class for all units is IP65 (IP67 to IP69 optional), and they can be used in ambient temperatures from -25 °C to +100 °C. Higher protection classes and an extended temperature range of -45 °C to +125 °C are available on special request.
