Rox® Sensor Packages and Mounting Adapters

Packages and adapters for Rox RTDs allow the sensor to be soldered in place, bolted down, or inserted into a hole. Gold-plated copper bobbins are available in order to heat sink leads. Appendix C: Sensor Packaging and Installation discusses techniques for the correct installation of cryogenic temperature sensors. Special packaging is also available—consult Lake Shore for custom orders.

Additional information about Lake Shore sensors and packaging can be found in our Temperature Sensor Selection Guide.

Each sensor package or adapter has been given a rating for four attributes or characteristics. These ratings give a general idea of how a package will perform and aid in the early decision making process, but are not a substitute for detailed specifications.

Rox® Packages
RX-BR

Packaging material: Thick ruthenium dioxide and bismuth ruthenate films with palladium silver contacts

Leads: None

Mass: ≤3.0 mg

CB
  • The RX-102B-CB (1000 Ω at room temperature) is useful down to 10 mK (calibrations available down to 20 mK) and monotonic from 10 mK to 300 K. The unique package design maximizes thermal connection and minimizes heat capacity at ultra low temperatures. The RX-102BCB is not interchangeable to a standard curve and not recommended for use in magnetic fields.
  • Can be mounted to any flat surface with a 4-40 or M3 screw

Packaging material: Thick ruthenium dioxide and bismuth ruthenate films on aluminium dioxide substrate with palladium silver contacts; epoxy attachment to OFHC adapter; copper leads indium soldered to chip and heat sunk to copper adapter using VGE 7031 varnish

Leads: 2

Lead material: 6 in 36 AWG copper leads with heavy build polyimide insulation

Mass: 3.5 g

Limitation: 0.01 K to 40 K

CD
  • AA canister sensor epoxied into a flat, copper bobbin with the sensor leads thermally anchored to the bobbin
  • Can be mounted to any flat surface with a 4-40 or M3 screw (not supplied)

Adapter material: Copper bobbin, gold-plated (AA canister epoxied to bobbin)

Leads: 0.91 m (36 in), 36 AWG, color-coded, Quad-Lead™

Lead material: Phosphor bronze Grade A alloy

Limitation: The epoxy limits the upper useful temperature of this configuration to 378 K

RX-AA

Adapter material: 

RX-102A-AA, RX-202A-AA, and RX-103A-AA: Thick ruthenium dioxide and bismuth ruthenate films with palladium silver contacts, indium solder, aluminum oxide substrate, sapphire header and copper canister with epoxy seal

RX-102B-CB: Thick ruthenium dioxide and bismuth ruthenate films on aluminum dioxide substrate with palladium silver contacts; epoxy attachment to OFHC adapter; copper leads indium soldered to chip and heat sunk to copper adapter using VGE 7031 varnish

Leads: 2

Lead material: 

RX-102-A-AA, RX-202A-AA, and RX-103A-AA: copper with heavy build Formvar® attached with epoxy strain relief at sensor - user should branch to 4 (no polarity)

RX-102B-CB: 6 in 36 AWG copper leads with heavy build polyimide insulation

Mass: 

RX-102-A-AA: 3.3 g
RX-202A-AA: 3.28 g
RX-103A-AA: 3.36 g
RX-102B-CB: 3.5 g

Limitation: The epoxy limits the upper useful temperature of this configuration to 400 K
