Omega Products HSRTD Installation Manual

GENERAL DESCRIPTION

The OMEGA HSRTD Flexible Sealed RTD
Sensor (RTD = Resistance Temperature
Detector) is designed for use in immersion
applications where the sensor needs to be
protected from moisture or corrosive
materials, or in small spaces where
temperature measurements up to 260°C
(500°F) are needed. The HSRTD’s small
cable-like design allows it to be easily
installed practically anywhere.

The HSRTD sensors are manufactured with
100 ohm Class A or B thin film RTD elements
whose resistance vs. temperature
characteristics conform to the International
Standard IEC 60751 (also known as DIN
Platinum RTDs). The sensing element comes
standard with four #26 AWG stranded nickel
plated copper extension wires that are PFA
insulated. The RTD element and extension
wires are enclosed in an extruded PFA jacket
which is sealed on the sensing end.

OPERATING INSTRUCTIONS:

1. Remove the sensor from its package and
place it into position. The sensor can be
taped or clamped if desired, but sharp
bends in the first 1 inch of the sensor are
discouraged.

2. Connect the extension wires to a
temperature measuring or controlling
device and you are ready to begin taking
temperature readings.
