Duct Temperature Sensors
Rigid Probe Rigid Probe – Bracket Mount Flexible Probe
Description
Siemens Duct Temperature Sensors monitor and
transmit changes in duct air temperature to the HVAC
control system. They provide an accurate, reliable
indication of duct air temperature. The sensor
resistance varies proportionally to the actual
temperature being measured.
Sensors are offered with a variety of probe lengths to
fit almost any size duct. Longer probes are typically
flexible for easier handling and installation (see
Product Ordering Information on the following page
for details).
Multiple output signals are available to ensure
compatibility with most common HVAC control
systems.
Features
• Variety of sensing elements.
• Suitable for multiple duct applications.
• Responsive to temperature change.
• Accurate and reliable indication of duct
temperature.
• Familiar installation process does not require
special tools.
