Wire Wound RTD Temperature Sensors and Transmitters
SERIES 200
BURNS
SERIES 200....
The Standard for RTD Technology.
A History of Quality
Since 1960, Burns Engineering has been an industry leader in the design and manufacture of temperature
sensors for the process and OEM industries. During that time, product quality and customer service along with
innovative design techniques have been top priorities in the Burns Engineering business philosophy. Our drive
to improve product quality is reflected in the Series 200, a “second” generation of RTD’s that are more accurate,
repeatable, stable and durable than any
previous models.
99.8% High Purity
Insulator
Designed for Reliability
The Series 200 is an “off-the-shelf” RTD
that meets real world conditions for
extended periods of time. Its unique design
and construction features improve the durability of the Series 200
without affecting its accuracy.

Sheath Design & Construction - A proprietary manufacturing
technique that forms the metallurgical bond between the element leads
and the internal sheath leads virtually eliminates
lead wire short out. And when encapsulated
with compacted ceramics, assures
durability and fast time response over the
life of the sensor. The Series 200 design
uses mineral insulated sheath with a
minimum bend radius of 3/4 inch to
accommodate installations requiring
flexibility and durability.

Burns CS Element Construction - This proprietary element is
constructed with a high purity platinum wire that is coil wound to
minimize stress and assure accurate readings over long periods of
time. Each coil is fully suspended in a high purity ceramic insulator
and surrounded by a ceramic powder with a new binder additive. The
"Burns Coil Suspension (CS) Element" enhances vibration and shock
resistance without interfering with the coils ability to expand or
contract. High strength platinum alloy leads have been increased in
size to improve durability and insure that the RTD does not open
circuit in tough applications.

SENSOR CONFIGURATIONS
Series 200 is a collection of the most frequently requested designs for industrial temperature
measurement. These standard sensors look like familiar configurations on the outside, but on the
inside, they are different. All Series 200 RTDs are built for high reliability and stability to
meet the tough operating conditions noted in the specifications.
Type “A” General Purpose Direct Immersion Assembly —Page 4
Suitable for mounting into tanks, pipes, ovens, furnaces, ducts, kilns,
process vessels and more.
Type “C” Spring Loaded for Thermowell Assembly — Page 6
Ideal for flow rates or product viscosity that would damage a more delicate direct immersion
probe. Spring loading provides protection from strong vibrations. Element can be easily
removed from the thermowell without removing the connection head, extension nipple, or
related conduit and wiring.
Type “K” Bayonet, Twist-lock, Spring Loaded for Thermowell Assembly —Page 6
Features easy access to the element with its quarter-turn bayonet lock fitting which engages with
the Burns number 5 explosion proof connection head.
Type “L” Spring Loaded Hex Fitting for Thermowells — Page 9
Features Burns’ self contained spring loaded hex fitting. This makes it ideal for mating to
virtually any connection head or transmitter assembly.
Type “G” Capsule Style —Page 12
Can resist 100% relative humidity. Ideal for environmental chambers, underground conduits, etc.

SERIES 200: TYPE ‘C’ AND ‘K’ SPRING LOADED
PLATINUM RTD AND THERMOWELL
High vibration endurance - The RTD and thermowell are kept in constant firm contact to prevent the
sensor assembly from vibrating against the thermowell. The compacted mineral insulated sheath
with high strength, corrosion resistant lead wires is the most durable construction possible.
Improved heat transfer - Faster response to temperature changes result from positive thermal contact.
Ease of installation - The thermowell, nipple and head may be installed without the sensor. The sensor may be
inserted or removed through the head and secured in place by means of the terminal block or twist lock fitting.
Wide selection of wells - See page 19 for thermowell styles and options.

How To Order
Burns Engineering has developed a flexible ordering system that enables you to choose exactly what you need for
your application. Basic Order Codes consist of standardized parts (items such as lead wire lengths and sheath
diameter). Each Ordering Information Page identifies the standard items on the drawing by the abbreviation “Std.”.
Options allow you to customize your order in a precise and documented manner for future use.

(completed order code for a Type “C” RTD sensor)
NOTE: Sheath length(x) can be determined by either of the following methods.
#1 Sheath length(x) = OAL - 1.5
Subtract 1.5 inches from the overall length (OAL) (see page 7 for OAL illustration)
x = 10.5 - 1.5
x=9
(10.5 is the measured overall length (OAL) of example #1 sensor)
#2 Sheath length (x) = N + A
Add the extension length (N) between thermowell and connection head to thermowell bore depth (A).
To determine bore depth (A) A = U + T + 1.5 for threaded wells
Since example #1 RTD had no options specified, the standard lengths for (N) and (T) would apply.
N = 3 and T = 0 are standard
A = 4.5 + 0 + 1.5
A = 6 inches
X=N+A
X=3+6
X = 9 inches
NOTE: Fill in all Basic Ordering Code Boxes.
Fill in option code box only when it applies, otherwise leave blank.

Model TL Transmitter
Model TLI Transmitter w/Integral Display
With .05% of span accuracy linearized with temperature, Burns Engineering transmitters
deliver twice the accuracy of most transmitters at about half the price of competitive
models in this performance range.
Both models feature:
• High accuracy: .05% of span
• Non-interactive wide range zero and span adjustment
• Outstanding ambient temperature range
• Low temperature coefficient
• State-of-the-art micro-circuit design
• Explosion-proof connection head (FM approved)
• EMI/RFI protected
Model TL features:

Function: Two Wire Temperature Transmitters are signal conditioning devices that amplify
the RTD signal input and transmit this signal to a recorder, controller, etc...via two standard
twisted pair copper wires. The transmitter is usually installed in the connection head as an
integral part of the Burns package. The transmitter may also be mounted separately from
the sensor on a nearby panel or “snap-track”.
Purpose: A head mounted transmitter greatly reduces the effects of electrical noise from
degrading the RTD signal on its way to the control room or read out location. Some of the
common causes of this accuracy degrading electrical noise are walkie-talkies, large electric
motors, a/c power lines etc....
Operation: By drawing current from a standard 24 VDC power supply (in proportion to the
resistance signal from the temperature sensor), it converts the highly sensitive measurement
signal into simple process current. This current loop will transfer temperature information over
a long distance, minimizing the problem of wire resistance or outside noise degrading accuracy.
The power source and the signal share the same pair of wires.
