The HCT Series LVDT transmitters are the perfect choice for high performance measurements in environments containing moisture, dirt, and fluid contaminants. Operating on a +10.5 to +28VDC loop voltage, the HCT delivers a smooth 4-20mA current loop output. True hermetic sealing of the coil assembly and electronics provides premium protection against adverse environments.
The integral electrical connector (welded, glass-sealed MS type) provides for easy installation and allows replacing a damaged cable without sacrificing the sensor.
Available in a number of standard linear measurement ranges from 0.25 to 10 inches, the HCT is ideal for process industries and power plant applications, or wherever high accuracy measurements are required in electrically noisy environments. The 2-wire 4-20mA current loop output is compatible with most PLCs.
Like in most of our LVDTs, the HCT windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high vibration and shock.
Captive core option: The HCT 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).
