Model Si-410 Silicon Diode Temperature Sensor

The Scientific Instruments Model Si-410 Silicon Diode Temperature Sensors operate over a wide temperature range and are miniature in size.

They are linear over a wide temperature range interval, and have high sensitivity in their lower range.

The Silicon Diode temperature sensors are interchangeable to a standard VIT curve.

Model Si-410 and Si-420 sensors are normally mounted in a gold-plated copper case with four 36 AWG polyimid coated, color-coded, phosphor bronze leads. Case size is 0.093" diameter by 0.250" long. Special leads of phosphorbronze or manganin wire at various lengths can be furnished at a minimum additional cost.

• Operate from 1.5 K to 450 K.
• Have a sensitivity of 40 mvjK
• Lead Material:
  Phosphor Bronze - Either two leaded or four leaded bonded cable,
  polyimide-coated 32 AWG or 36 AWG . Conductors are color coded.
  Phosphor Bronze exhibits good electrical conductivity, but poor thermal
  conductivity. Resistivity is 2.7 Ohms per foot.
  Stranded Copper - Teflon-coated wire either two leaded 30 AWG or
  two and four leaded 36 AWG. Conductors are color coded. Copper
  exhibits good electrical and thermal conductivity.
  Resistivity is 0.6 mill i-Ohms per foot.
  Manganin - Either two lead or four lead polyurethane-coated 36 AWG.
  Conductors are not color coded. Exhibits good electrical conductivity,
  but poor thermal conductivity. Resistivity is 11.8 Ohms per foot.
  Manganin is not easy to work with.

• Our Silicon Diode temperature sensors are available in both
  two and four lead configurations:
  Two Lead Configuration -This configuration does not compensate
  for lead resistance. Therefore, slight errors in sensor
  resistance/voltage can be induced. The magnitude of the error
  is proportional to the length of the leads.
  Four Lead Configuration - This configuration provides the highest
  accuracy by compensating for lead wire resistance.
• Fundamentally, cryogenic temperature sensors are supplied in
  three categories:  
  Uncalibrated
  Grouped
  Calibrated
