Flexible Lead NTC Thermistors

CWW Ceramic Wire-Wound platinum RTD Elements from Sensor Technology Ltda. are characterised by their extremely high stability, high-temperature capability and high accuracy over a very wide temperature range.  Sensors can measure the temperature of gases, liquids and solids, from -196ºC to 850ºC, with a precision between 0.012Ω and 0.12Ω at 0ºC or between 0.03°C and 0.3°C at 0°C.

The ceramic RTD construction design consists of a platinum wire coil (or for Duplex versions, two coils) encapsulated in a very high purity, aluminium oxide ceramic tube.  The empty spaces remaining between the platinum coil and the internal tube walls are filled with a material which allow the platinum contraction and expansion movement during temperature variations.

CWW RTD elements have multiple applications, such as laboratory, process technology and high value-added equipment. Applications where a highly accurate measurement is necessary should be built with this sensor type and 4 extension wires, however 3-wire construction is the most commonly found.

ATC Semitec stocks an extensive range of auto-reset, manual reset and self-hold thermal protection devices from some of the world’s leading manufacturers such as PEPI, ASAHI, SEFUSE, EAW and SEKI.

Thermal protectors are used as safety mechanisms which will protect your products from overheating in the result of an abnormal operating condition.  The thermal cut-outs will protect against an over-temperature situation which could ultimately help to prevent fires or major damage to electrical components or appliances.

YAGEO Nexensos manufacture a wide selection of platinum temperature sensors for diverse industries, measuring process temperatures, regulating heating systems and compensating for temperature fluctuations at component level.

The thin film RTD elements were originally manufactured with lead-wires for PCB mounting and use in sensor assemblies.  As surface mount technology rapidly developed, the need for SMD Pt100 or Pt1000 sensor elements led to the development of various SMD formats.

1206 chip sizes were the first to appear but as electronic components got smaller, the chip sizes of Pt elements shrank accordingly so that today we can offer 0805 and 0603 Pt100s and Pt1000s as well – 0402 size chips will inevitably follow shortly!
