DIELECTROMETER SENSORS

Brand Owner Address Description
IDED JENTEK Sensors, Inc. 121 Bartlett Street Marlborough MA 01752 Dielectrometer sensors, probes and sensor arrays, designed for measuring electrical properties, such as conductivity and permittivity, of materials, such as insulators and semiconductors, and geometric properties, such as layer and coating thickness, of multilayered and coated manufactured goods, such as adhesive tapes, display materials, paints and laminates, and used for process and quality control of the manufacture of epoxy, polymer, cellulose, cement, ceramic, and fiberglass composite parts, such as turbine blade coatings, battery separators, pressboard insulation, and wind turbine blades; for field inspections and degradation monitoring of cement or polymer-based structures such as bridges, roads and pipes; for object detection and discrimination such as detection of buried objects such as plastic and metallic landmines, reinforcement bars in concrete, buried pipes, unexploded ordnance, archaeological artifacts and environmental hazards; and for relating electrical properties of materials and manufactured goods, such as those mentioned above, to mechanical or other process properties, such as state of cure, porosity, water content, toxic chemical absorption, flaw size, and interfacial electrochemical parameters;

Technical Examples
  1. In downhole drilling tools, a first set of inexpensive and/or relatively small sensors that typically have lower accuracy and higher drift than conventional downhole sensors are located in the drill string adjacent to the bit. A second set of highly accurate sensors is located in a more protected location higher in the drill string away from the drill bit. As drilling progresses these sensors pass through the same portion of the formation measured by the first set of sensors. Key properties are measured by the second set of sensors which allow a calibration offset to be applied the data measured by the first set of sensors.
