RTD-200 Temperature Sensor for Ambient Sensing
APPROVALS
Approvals associated with control device, however not to be used in Div. 1 areas.
DESCRIPTION
The nVent RAYCHEM RTD-200 is a three-wire platinum RTD (resistance-
temperature-detector) typically used with electronic control systems that
require accurate ambient temperature sensing. The RTD-200 comes with a 1/2”
NPT fitting that installs to the appropriate conduit box. This allows mounting
of the RTD in a typical ambient location. This also allows for splicing of RTD
extension wire back to the controller.

SPECIFICATIONS
Sensor
Housing| 316 stainless steel
Dimensions| 3 in (7.6 mm) length 1/4 in (6 mm) diameter
Accuracy| ±0.3°F (0.2°C)
Range| –100°F to 300°F (–73°C to 149°C)
Resistance| 100 ohms +/– .25 ohm at 0°C
X=0.00385 ohms/ohm/°C
Extension Wires
Wire size (each of 3)| 22 AWG
Note: The length of RTD extension wires is determined by the wire gauge
used.
To reduce the likelihood that electrical noise will affect temperature
measurement, keep RTD extension wires as short as possible. Use shielded
instrument cable such as nVent RAYCHEM MONI-RTD-WIRE (22 AWG, PVC insulation,
–30°F to 140°F, –20°C to 60°C) or Belden 83553 (22 AWG, FEP insulation, –95°F
to 395°F, –70°C to 200°C).
Wire dielectric strength| 600 volts
Length| 6 ft (1.8 m)
Outer jacket| Fluoropolymer
Maximum exposure
temperature| 300°F (149°C)
Sensor fitting| 1/2-in NPT with sealing washer and nut
WARNING:
This component is an electrical device. It must be installed correctly to
ensure proper operation and to prevent shock or fire. Read these important
warnings and carefully follow all the installation instructions. Component
approvals and performance are based on the use of specified parts only. Do not
use substitute parts or vinyl electrical tape to make connections.
INSTALLATION
The RTD-200 can be terminated directly at the controller using the supplied
1/2 in NPT fitting. In this configuration, no additional extension wire is
required.
RTD wired directly to controller
(Distance from sensor bulb to controller must be less than 4 ft)
Note: RTD should be placed in a typical ambient location. RTD wired
with splice box
Note: RTD should be placed in a typical ambient location.
