HCD series LVDT

Product Description

The HCD Series hermetically sealed DC operated LVDTs are the perfect choice for high performance measurements in environments containing moisture, dirt, and fluid contaminants. Operating on a nominal ±15VDC supply, these heavy-duty LVDTs deliver an extremely linear, low noise, yet high frequency response ±10VDC output. The integral electrical connector (welded, glass-sealed MS type) provides for easy installation and allows replacing a damaged cable without sacrificing the sensor. The HCD is available in stroke ranges of ±0.05 inch [±1.27mm] up to ±10 inches [±254mm], and with a number of standard options including imperial or metric threaded core, guided core and captive core. 

Like in most of our LVDTs, the HCD windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a twocomponent epoxy. This provides excellent protection against hostile environments such as high vibration and shock. Captive core option: The HCD features an optional captive core design (available for most models) that greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for self-alignment, while a PTFE sleeve allows low-friction travel through the stainless steel boreliner (spool tube). The core rod and the bearing assembly are both field serviceable.
