Supported Applications
The Omega RTD-870 and RTD-880 series are bracket-mounted Resistance Temperature Detector (RTD) probes designed for air, gas, and liquid temperature sensing. The product overview identifies these sensors as suitable for appliance, laboratory, and industrial use.
Operating Conditions & Performance
The series operates within a process temperature range of -70 to 500°C. Sensors feature a sheath constructed from 300 Series Stainless Steel with an overall diameter of 5 mm (0.195"). The "A" dimension, representing the insertion length, can be immersed in liquid up to the mounting flange.
Electrical characteristics include #24 AWG stranded nickel-plated copper lead wires insulated with fiberglass. A documented note specifies that the two lead wires add 0.30 Ω of lead resistance to the circuit.
Configuration Options
The series offers configurable insertion lengths and electrical connection options:
- Insertion Lengths ("A" Dimension): Available in 51 mm (2") for Model RTD-870 or 152 mm (6") for Model RTD-880.
- Sensing Elements: Configurable with element resistances of 100, 500, or 1000 Ω at 0°C. Temperature coefficients include 0.00385 and 0.00375 Ω/Ω/°C.
- Connectors: Options for SHX miniature connector or NHX miniature connector are available.
- Housing & Mounting: Features a mounting bracket constructed from 300 Series Stainless Steel to facilitate easy installation.
The model number guide follows the format: RTD - - - OHMS. For example, an ordering code may appear as RTD-870-100OHMS or include a temperature coefficient placeholder.
Key Product Differences
The primary distinction between the two models in this series is the insertion length ("A" dimension). Model RTD-870 provides a 51 mm (2") sensing element, while Model RTD-880 offers a longer 152 mm (6") configuration. Both share identical sheath materials and mounting bracket designs.
Available configurations include DIN platinum elements with specific resistance values such as the 100 Ω, 0.00385 element referenced in ordering examples like RTD-870-1000OHMS (noting that the example text cites a 1000 OHMS suffix while describing a 100 Ω element).
