RTD-831 Series
Bolt-On RTD Sensor with Aluminum Flag Housing
Omega's RTD-831 series 3-wire RTD sensor features an
improved barrel and ag design on the aluminum housing
which gives improved durability. The ag is machined to
accept various size screws for easy installation on at
surfaces by either being bolted or cemented onto the
surface. This is available in 100 Ω or 1000 Ω Platinum RTD
element and is available in a high temperature (-HT) version.
Connection options available are miniature 3-pin connector
(-MTP), standard 3-pin connector (-OTP), stripped ends
(-SE), and spade lugs (-LUG). For other connector types,
please contact Sales. Applications for this type of sensor
include product performance testing; climate control/HVAC;
monitoring and control of processes; hot plate equipment,
and process pipes.
