The first with a button

The pressure-tight installation of displacement sensors in hydraulic systems can be very complex, as the core and core extension must first be mounted, then the pressure tube must be screwed in place, and finally the sensor must be mounted on top. To simplify the process, Inelta Sensorsysteme has developed and launched the first digital LVDT-based displacement sensor with a pushbutton and internal spring for hydraulic applications.

This model series is called the LVDT-IHDT and operates with digital signal processing in a wide supply voltage range of 9...32 VDC. Both the measuring length and the current or voltage output signals are programmable on-site using an external handheld device. An IO-Link interface is in development. Another special feature is the sensor's excellent mechanical stability.

The LVDT-IHDT model is vibration-resistant up to 30 g, suitable for a temperature range of -25 °C to +85 °C, and achieves protection class IP6K9K (ISO 20653). The high-precision digital position sensor is designed for pressure ranges up to 400 bar. Bypass holes in the bearing ensure that the hydraulic fluid can flow past the sensor. Sensor properties such as flange, supply voltage, and pressure range can be customized upon request.
