The SA1-RTD surface-mount RTD
temperature sensor mounts on flat
or curved surfaces and provides
Class A accuracy for critical
temperature monitoring applications.
Based on a 2 x 2 x 0.8 mm thin-film
platinum RTD and supplied in
PFA-insulated 3- or 4-wire
configurations (connectors optional),
it can be customized for use in
a wide variety of applications.
The sensor can be easily applied
using its self-adhesive backing,
or permanently mounted using
OMEGABOND® cements.

Use the SA1-RTD to monitor chip,
heat sink, and environmental
temperatures in electronic devices;
check piping or ducting temperatures;
monitor motor and transformer core

Overbraid!

For applications where electrical noise
is prevalent, or where the sensor
lead wires may be routed around
sharp objects, consider the stainless
steel overbraid option. To specify this
option, add “-SB” to the end of the
model number for an additional cost
per meter (foot). Ordering example:
SA1-RTD-80-SB.

The self-adhesive sensor is ideal for
“targeted” placement on curved or flat
surfaces. Once in place, it can be used
“as is” for measuring temperatures in
applications such as machine tools,
electronic products, structures or other
places where temperatures need to be
monitored and controlled.
