HSE/HSER 750 Series of 3/4-in.-dia. DC-operated linear-variable-displacement transducers
Enclosed in a heavy-wall, stainless steel housing, the HSE/HSER 750 Series of 3/4-in.-dia. DC-operated linear-variable-displacement transducers (LVDTs) are impervious to dirt, water, steam and other corrosive elements. The units are ideal for use in hydraulic-cylinder positioning, valve-position sensing, automatic assembly equipment and other industrial applications with hostile conditions. Incorporating built-in electronics, the sensors provide the desirable features of an AC-LVDT, such as frictionless operation and dynamic response, with the simplicity of DC input and pre-calibrated DC output. Units operate in conjunction with programmable logic controllers (PLCs), digital indicators, computer-based data processors and quality-control (QC) data collection systems. Available in ranges from 0.100 in. to 20.00 in., the LVDTs feature high resolution, a repeatability error of less than ±0.01% of full-scale output (FSO), and a hysteresis error of less than ±0.01% of FSO. The standard maximum linearity error is ±0.25% of FSO. The units operate at temperatures from 0°F to 160°F and pressures up to 1,000 psi.

DMC Dual Channel linear variable differential transformer (LVDT) controllers
These DMC Dual Channel linear variable differential transformer (LVDT) controllers can be used in a variety of industrial measurement and control applications within the petrochemical, power generation and manufacturing industries. Easily programmable, these controllers offer precise measurement for applications utilizing AC and DC inputs. A scrolling display on the controller actively guides users on what information is necessary for input. The DMC Dual Channel Controllers feature a graphical user interface that enables operators to quickly calibrate and set up the sensors, retrieve or send programs, and view and collect data remotely through a computer via an RS-232 or Ethernet connection. They have microprocessor-based logic and feature advanced software that provides digital position indication and cross-channel path and control functions for advanced monitoring, measuring and control requirements. The programmable input averaging, digital filtering and HI/LO-limit detection make the controllers especially suitable for Go/No-Go applications, such as process gaging and quality control.

LP750 Series linear-position sensors
Non-contacting LP750 Series linear-position sensors have an excellent stroke-to-length ratio, making them suitable for long-stroke applications. The sensors operate at distances from 0–4 in. to 50 in., and because they can be almost the same length as the stroke, they can replace failing potentiometers in many industrial position-measurement applications, such as machine tool positioning, hydraulic cylinder positioning, valve position sensing, and automated assembly. The sensors are constructed entirely of stainless steel and are hermetically sealed to withstand the harsh and corrosive environments that are typically found in steel mills, power plants, and petrochemical plants.
