Suitable for harsh environments
April 22, 2015 - Frisco, TX -
The LVDT sensors operate on the principle of the differential transformer and are suitable for use in many applications, such as medical technology, industrial, seafaring, in testing facilities, machinery construction, special purpose machines and agriculture.
Thanks to the housing made from chemically nickel-plated steel with IP65 type of protection (optional IP68) and a temperature range of -25 to +85°C, which can be expanded on request, the LVDT sensors are suitable for use in harsh environments. Due to their external thread, the devices are easily installed and adjusted. Unlike competing smooth designs, there is no need for them to be clamped with grub screws which can damage the housing and distort the measured value. The connection takes place via a M12 connector or a cable.
They are available as M12 or M18 versions with external thread and capture measuring lengths of up to 2, 5, 10 or 20 mm, depending on the model. It is actuated by an unguided core or a switch with internal spring. The linearity tolerance of the sensors is ± 0.5%.
The M18 sensors come with integrated electronics and a current or voltage output. For the M12 models, users can choose between various signal amplifiers which generate output signals ranging from 0 to 5 V, 0 to 10 V, ± 5 V, ± 10 V, 0 to 20mA or 4 to 20mA.
Custom sensor designs with other configuration options, such as improved linearity tolerance or individual calibrations, are also available. An online configuration guide and questionnaire with optional capabilities are provided to make it easy for design engineers to create their own custom designs.
A wide range of input systems, precision potentiometers, filling level sensors, LVDT, Ultrasonic and load cell sensors can be found at http://www.hoffmann-krippner.com
TE Connectivity's HDC Dynamic Module integrates the Dynamic series flexible signal and power solutions and the HDC Heavy Duty Connector series to form a solution of harsh environment connectors. TE's HDC Dynamic Module offers the top features of the two series. It uses the contact concept of the Dynamic series, with its proven performance in industrial uses and its cost effectiveness compared to legacy cutting contacts. The HDC connectors make the module a reliable solution for harsh environments. TE's HDC Dynamic Module supports 2A/32V to 40A/300V performance and 3 positions to 48 positions.
