  •     Temperature, maximum : 250 °C
  •     Frequency, mid-con mode : 0.1 Hz ~ 100 KHz
  •     Frequency, high-con mode : 0.001 Hz ~ 100 KHz
  •      No interference with the flow of material during processing.
  •      Silver-palladium electrodes embedded in an alumina substrate.

 

The Ceramicomb-1” is designed for use in presses, molds or harsh environments where a rugged, reusable dielectric sensor is desired.

 

The Ceramicomb-1inch is designed for use in presses, molds or harsh environments where a rugged, reusable dielectric sensor is desired. It may be mounted so the electrodes are flush with a platen or mold surface, insuring no interference with the flow of material during processing. The sensor is constructed with silver-palladium electrodes embedded in an alumina substrate, protected by a stainless steel sheath with a nominal 1.0 inch (2.54 cm) diameter. A thermocouple is positioned in the ceramic just below the surface to allow measurement of process temperatures. Dielectric and thermocouple signals are routed through a 10-foot (3 m) long stainless steel conduit to high temperature connectors. Sensor and cabling are rated for operation up to 250 degrees C and are suitable for R&D, QA/QC and manufacturing applications with repetitive operations.
