Bestech Australia releases HSD and HSDR 750 series DC-operated LVDTs

Bestech Australia has released the HSD and HSDR 750 series of 19 mm diameter DC-operated Linear Variable Differential Transformers (LVDTs) from American company Macrosensors.

The units are constructed with stainless steel and are hermetically sealed, making them impervious to dirt, water, steam and other corrosive elements.

The company says the devices are are ideal for use in industrial applications with hostile conditions and corrosive environments. 

The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial (HSD) or radial (HSDR) connector. 

The radial connector results in a through-bore design, which permits access to either or both ends of the LVDT’s core for better mechanical support and core guidance, and easier cleanout in dusty or dirty locations. 

It also results in a shorter installed length compared to the units with axial connectors. 

The mating connector plug is supplied with the unit.

According to the manufacturer, the linear position sensors use built-in electronics to provide the features of an LVDT, such as frictionless operation and dynamic response, with the added convenience and simplicity of DC input and precalibrated DC output. 

The LVDTs feature the high resolution, excellent repeatability and low hysteresis associated with LVDT technology, and the maximum linearity error is ±0.25% for these sensors.

Operating from ±15V DC input, the hermetically sealed position sensors offer a pre-calibrated 0 to ±10V DC output that is ideal for easy integration with PLCs, digital indicators, A/D converters, computer-based data processors and QC data collection systems.

Customisation of these LVDT position sensors is also possible, with options including Teflon bore liners and metric threaded cores, as well as smaller diameters and low mass cores.
