Measuring principle Resistance thermometer (RTD)

These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. The
temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at
0 °C (32 °F) and a temperature coefficient α = 0.003851 °C-1.

There are generally two different kinds of platinum resistance thermometers:

• Wire wound (WW): Here, a double coil of fine, high-purity platinum wire is located in a ceramic
support. This is then sealed top and bottom with a ceramic protective layer. Such resistance
thermometers not only facilitate very reproducible measurements but also offer good long-term
stability of the resistance/temperature characteristic within temperature ranges up to
600 °C (1 112 °F). This type of sensor is relatively large in size and it is comparatively sensitive to
vibrations.

• Thin film platinum resistance thermometers (TF): A very thin, ultrapure platinum layer,
approx. 1 μm thick, is vaporized in a vacuum on a ceramic substrate and then structured
photolithographically. The platinum conductor paths formed in this way create the measuring
resistance. Additional covering and passivation layers are applied and reliably protect the thin
platinum layer from contamination and oxidation, even at high temperatures.

The primary advantages of thin film temperature sensors over wire wound versions are their smaller
sizes and better vibration resistance. A relatively low principle-based deviation of the resistance/
temperature characteristic from the standard characteristic of IEC 60751 can frequently be observed
among TF sensors at high temperatures. As a result, the tight limit values of tolerance category A as
per IEC 60751 can only be observed with TF sensors at temperatures up to 200 °C (392 °F).

RIA16 Field indicator

The field indicator records an analog measuring signal and shows this on the display. The LC display
shows the currently measured value digitally and as a bargraph with limit value violation signalling.
The indicator is looped into the 4 to 20 mAcircuit and obtains the required energy from there.

RNS221 Power supply

The power supply unit (24 VDC, 30 mA) has two galvanically isolated outputs for supplying voltage to
loop powered transmitters. The two channel device has a wide-range input for mains power,
20 to 253 VDC/AC, 50/60 Hz to be used in any electrical circuit. Details see Technical Information.

Equipment architecture

Measurement range

Output signal

The single and duplex element RTDs are designed to measure temperature in a variety of process and
laboratory applications. These RTDs are specifically designed for use in two different process
temperature ranges and they will provide accurate and repeatable temperature measurement
through a broad range of –200 to 600 °C (–328 to 1 112 °F). Low range thin film RTDs
–50 to 200 °C (–58 to 392 °F) are constructed using silver plated copper internal leads, PTFE wire
insulations with potting compounds to resist moisture penetration. High range RTDs
–200 to 600 °C (–328 to 1 112 °F) are constructed with nickel internal leads inside swaged MgO
insulated cable to allow higher temperature measurements at the RTD element and to provide
higher temperature lead protection along the sheath.

Output

Generally, the measured value can be transmitted in one of two ways:

• Directly-wired sensors - sensor measured values forwarded without a transmitter.

• Via all common protocols by selecting an appropriate Endress+Hauser iTEMP temperature
transmitter. All the transmitters listed below are mounted directly in the terminal head or as field
transmitter and wired with the sensory mechanism.

Family of temperature transmitters

Thermometers fitted with iTEMP transmitters are an installation-ready complete solution to
improve temperature measurement by significantly increasing accuracy and reliability, when
compared to direct wired sensors, as well as reducing both wiring and maintenance costs.

PC programmable head transmitters

They offer a high degree of flexibility, thereby supporting universal application with low inventory
storage. The iTEMP transmitters can be configured quickly and easily at a PC. Endress+Hauser offers
free configuration software which can be downloaded from the Endress+Hauser Website. More
information can be found in the Technical Information.

HART® programmable head transmitters

The transmitter is a 2-wire device with one or two measuring inputs and one analog output. The
device not only transfers converted signals from resistance thermometers and thermocouples, it also
transfers resistance and voltage signals using HART® communication. It can be installed as an
intrinsically safe apparatus in Zone 1 hazardous areas and is used for instrumentation in the
terminal head (flat face) as per DIN EN 50446. Swift and easy operation, visualization and
maintenance using universal device configuration tools like FieldCare, DeviceCare or
FieldCommunicator 375/475. For more information, see the Technical Information.

PROFIBUS® PA head transmitters

Universally programmable head transmitter with PROFIBUS® PA communication. Conversion of
various input signals into digital output signals. High accuracy over the complete ambient
temperature range. The configuration of PROFIBUS PA functions and of device-specific parameters is
performed via fieldbus communication. For more information, see the Technical Information.

The units are factory tested with 500 VAC for one minute between live parts (terminals) and exposed
non-current-carrying metal parts (e.g. probe sheath).

RTD elements are passive resistances that are measured using an external current. This
measurement current causes a self-heating effect in the RTD element itself which in turn creates an
additional measurement error. In addition to the measurement current, the size of the measurement

Calibration specifications

error is also affected by the temperature conductivity and flow velocity of the process. This self­heating error is negligible when an Endress+Hauser iTEMP temperature transmitter (very small
measurement current) is connected.

The manufacturer provides comparison temperature calibrations from
–20 to +300 °C (–4 to +572 °F) on the international temperature scale of 1990. Calibrations are
traceable to standards maintained by the National Institute of Standards and Technology (NIST).
Calibration services are in conformance with ASTM E220, IEC 17025 and ANSI/NCSL Z540-1-1994.
The report of calibration is referenced to the serial number of the RTD assembly.

Three point calibrations are provided, given that the specified temperatures are within the
recommended range and the minimum length requirements are met as specified. The minimum
length is 6 in.

A-B In pipes with a small cross section the sensor tip should reach or extend slightly past the center line of the

pipe (=X).

C-D Tilted installation

Ambient temperature range

The immersion length of the thermometer influences the accuracy. If the immersion length is too
small then errors in the measurement are caused by heat conduction via the process connection and
the container wall. If installing into a pipe then the immersion length should be at least half of the
pipe diameter. A further solution could be an angled (tilted) installation (see C-D). When
determining the immersion length all thermometer parameters and the process to be measured
must be taken into account (e.g. flow velocity, process pressure).

• Installation possibilities: Pipes, tanks or other plant components

• Minimum immersion length should be 10 times the OD of the sheath, nominal.

The calculation was done for pipes only, for MgO insulated sensors the values might be higher.
In any case for different lengths, other materials, variation in sheath diameter or wall
