| Description |
| |
|
Ruthenium oxide temperature sensors
are thick-film resistors used in applications
involving magnetic fields. These composite
sensors consist of bismuth ruthenate,
ruthenium oxides, binders, and other
compounds that allow them to obtain
the necessary temperature and resistance
characteristics. Each Lake Shore Rox™
model adheres to a single resistance versus
temperature curve. |

| RX-102A |
The RX-102A (1000 Ω at room
temperature) is useful down to 50 mK and
has better interchangeability than the
RX-202A as well as low magnetic field induced
errors below 1 K. |
| |
| RX-102B-CB–10 mK calibrations coming soon! |
| 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. |
| |
| RX-202A |
The RX-202A (2000 Ω at room temperature)
has a 4× improvement
in magnetic field-induced errors over
other commercially available ruthenium
oxide temperature sensors with similar
resistances and sensitivities. Most
ruthenium oxide sensors have a maximum
useful temperature limit well below
room temperature, where the sensitivity
changes from negative to positive.
The RX-202A however, is designed to have
a monotonic response from 0.05 K up to
300 K. |
| |
| RX-103A |
| The RX-103A (10,000 Ω at room
temperature) has a unique resistance
and temperature response curve
combined with low magnetic fieldinduced
errors, and is the best choice for
interchangeability from 1.4 K to 40 K. |
