DC LVDT displacement transducer for harsh environments
1 - 10 '' | HSI, HSIR 750 series Macro Sensors

Macro Sensors' HSI and HSIR 750 Series of 3/4 inch (19 mm) diameter, loop-powered 4-20 mA LVDT position transmitters are designed for a wide range of position monitoring and feedback applications. These rugged hermetically sealed sensors are constructed entirely of stainless steel, and are intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and input/output connections are made through a sealed axial (HSI) or radial (HSIR) connector. The radial connector offers two important benefits. First, it 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. The second advantage of the radial connector is shorter installed length compared to units of the same range with axial connectors. The mating connector plug is supplied with the unit.

HSI and HSIR 750 Series transmitters offer the frictionless operation, high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, along with the convenience and simplicity of precalibrated 4-20 mA current loop operation. Units operate either as 2-wire loop-powered or 3-wire sourcing externally powered. The built-in electronics operate over a wide range of loop supply voltages and resistances, and are designed to operate with many PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.
