RTD-805-RTD-806

Supported Applications

The Omega RTD-805 and RTD-806 series are Air Temperature RTD Sensors designed for monitoring air and gas streams. These sensors feature an exposed sensing element optimized for fast response times in air applications. Documented use cases include air temperature monitoring and control in laboratories and laminar flow benches.

Operating Conditions & Performance

The series utilizes a 100 Ω Class 'A' DIN platinum element with IEC Class A accuracy, specified as ±0.15°C @ 0°C. The maximum process temperature is rated to 230°C (450°F). Both models employ 3-Wire Construction for connecting to most instruments.

Physical dimensions include a probe diameter of 16 mm (5/8") and a stem length of 32 mm (1¼"). The sensing element is exposed, providing fast response times in air environments. Class 'B' accuracy options are also available in economical 3-packs.

Configuration Options

The series offers configurable termination and housing materials to suit specific installation needs:

• Housing Materials: Available with Stainless Steel or Plastic housings.
• Cable Specifications: Standard 1 m (40") PFA insulated cable on both RTD-805 and RTD-806 models.
• Termination Options:
  • (Blank): Miniature connector standard
  • -OTP: Heavy-Duty Connector
  • -TA3F: Audio Connector
  • -LUG: Copper Lugs (Terminal lugs)
• Compatible Accessories: The series supports integration with the iDRN-RTD digital signal conditioner, PUK-2T-10PK DIN rail terminal block (10 pack), CN606RTD3 6-zone ¼ DIN temperature monitor, and OM-CP-OCTRTD 8-channel data logger.

Model numbers follow the format RTD - <MODEL> - <TERMINATION OPTION>, such as RTD-805-TA3F or RTD-806-LUG. The standard MTP male connector is shown, with mating connectors sold separately.

Key Product Differences

The primary distinction between the two base models lies in their specific model codes and available termination configurations:

• RTD-805: Features a 100 Ω Class "A" DIN sensing element with a standard 1 m (40") PFA insulated cable. Max temperature is 230°C (450°F).
• RTD-806: Identical in sensing element and max temperature to the RTD-805, but frequently referenced with specific termination options such as -OTP or -LUG.

Variants differ by their selected connector type (Miniature, Heavy-Duty, Audio, or Terminal Lugs) rather than internal sensor performance. Both models are Made in USA.
