Function and system design

Measuring principle 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

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 (1112 °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).

A0016255-EN

RIA16 Field indicator

The field indicator records an analog measuring signal and shows this on the display. The LCD 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 mA circuit and obtains the required energy from there. Details see Technical Information (see "Documentation").

RNS221

The RNS221S power supply (24 V DC, 30 mA) has two galvanically isolated outputs for supplying voltage to loop powered transmitters. The two channel power supply has a wide-range input for mains power, 20 to 253 V DC/AC, 50/60 Hz to be used in any electrical circuit. Details see Technical Information (see "Documentation"). RNS221 is an UL recognized component to UL-3III-1.

Details see Technical Information (see "Documentation").

Equipment architecture The single 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 1112 °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 1112 °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.
