Measuring principle

Measuring system

These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. This
temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at
0 °C (32 °F) and a temperature coefficient is 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 approx. 300 °C (572 °F).
For this reason, thin-film sensors are generally only used for temperature measurements in ranges
below 400 °C (932 °F).

 1 Example of an application of the temperature assemblies

Water - heat Differential

Calculation of heat quantity which is emitted or absorbed by a water flow in a heating or cooling
system. The quantity of heat is calculated from the process variable for Dp flow (Q) and the
differential from the feed and return temperature (T2 - T1). Bidirectional energy calculations, such
as the calculating systems with changing flow direction (charging/discharging the heat accumulator)
are also possible.

sales or production. For Deltabar S & Cerabar S details see Technical Information.

Equipment architecture

Measured variable

Measuring range

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.

Low temperature range 25 s 30 s 35 s

Response times for RTD assemblies with thermowell are provided for general design guidance
without transmitter.

When the temperature of a process media changes, the output signal of a RTD assembly follows this
change after a certain time delay. The physical cause is the time related to heat transfer from the
process media through the thermowell and the insert to the sensor element (RTD). The manner in
which the reading follows the change in temperature of the assembly over time is referred to as the
response time. Variables that influence or impact the response time are:

• Wall thickness of thermowell

• Spacing between RTD insert and thermowell

• Sensor packaging

• Process parameters such as media, flow velocity, etc.

Self heating

Calibration specifications

RTD elements are not self-powered and require a small current be passed through the device to
provide a voltage that can be measured. Self-heating is the rise of temperature within the element
itself, caused by the current flowing through the element. This self-heating appears as a
measurement error and is affected by the thermal conductivity and velocity of the process being
measured; it is negligible when an Endress+Hauser iTEMP temperature transmitter is connected.

Minimum length requirements for calibrated sensors = 6"

Use option "B" (Block: Test; calibration) for RTD calibration, the three temperature points need to be
specified in 5 °C (9 °F) increments.

The manufacturer provides comparison temperature calibrations from
–40 to +215 °C (–40 to +420 °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 based on overall length ’x’ of the spring loaded insert.

Process

Thermowells are used in measuring the temperature of a moving fluid in a conduit, where the
stream exerts an appreciable force. The limiting value for the thermowells is governed by the
temperature, the pressure and the speed of the medium, the immersion length, the materials of the
thermowells and the medium, etc. Calculations for stress and vibration of thermowells can be done
according to ASME PTC 19.3-1974 standard, please consult Endress+Hauser.
