WINONA, MN, USA – November 30, 2006 – Carlo Gavazzi, a leading manufacturer of sensing devices, has utilized RTP Company’s PermaStat PLUS compounds to meet the stringent ATEX Directive requirements in its Tripleshield Capacitive Sensors. In order for the sensors to comply with ATEX regulations, the conductive housing must have a surface resistance less than 109 ohm and the ability to withstand impact testing. “The thermoplastic compounds from RTP Company are more consistent than our other possible choices,” said Michael Nolsøe Larsen, Quality Manager at Carlo Gavazzi Industri A/S.
“Because of our decision to specify an RTP Company compound, we believe that the risk of critical errors in our sensing devices will be minimized.”Capacitative sensors are used in industrial and agricultural applications to detect both conductive and non-conductive materials – such as water, glass, plastics, and metals – without physical contact.The sensors use a PermaStat PLUS 1000 series glass-reinforced PBT compound, which is ideally suited for the application and fulfills the demands of the ATEX standard. This compound is permanently static dissipative and provides the necessary surface resistance to meet the ATEX requirement of less than 1 Gohm.
It has high impact properties and excellent resistance to a broad range of chemicals, and the glass reinforcements provide a two-to threefold increase in tensile, flexural, and compressive properties. “RTP Company through Nordic Plastic Service provided all the necessary technical assistance and service,” said Michael Nolsøe Larsen. “We have been very grateful for the speedy response from RTP Company with the ATEX testing and reports, which have been extremely useful in our procedure.”
