Platinum RTD Probes

  100, 500 or 1000 ohm elements
  0.00385 alpha (IEC751) coefficient
  Thin film (to 500C), ceramic/glass (to 850C)
  316 stainless steel probe sheath
  Many sizes, fittings, leads and terminations

Platinum RTD's are the sensor of choice for wide temperature ranges. They are very stable and accurate. They provide a high signal level and thus require generally less expensive instrumentation than other types of sensor. Overall system cost is reduced and the need for recalibration is less frequent. Probes are interchangeable and offer high reliability. Resistance change with temperature is linear (positive).

In addition to standard probes, many special configurations are offered. For example:

Shrink tube sealed
Bayonet lock cap with spring cable
Air probe with mounting flange
Armored cable : plastic air probe
Epoxy sealed
Surface temperature probe
Angled probe

STYLE AND TYPES AVAILABLE
