TSA101

What is this component used for?

It is an exchangeable temperature measuring inset used inside compatible industrial temperature assemblies. It allows the sensing element (RTD or thermocouple) to be replaced or reconfigured without changing the whole sensor installation, depending on the design of the thermometer and thermowell.

What sensor technologies are available?

Common configurations include RTD elements (such as Pt100 and Pt1000) and thermocouple elements. The available option set depends on the specific TSA101 build (type code) and whether a transmitter is fitted.

What accuracy classes can be selected for RTD versions?

RTD versions can be specified with IEC 60751 accuracy classes such as Class B, Class A, and (for selected thin-film versions) Class AA. The exact accuracy and temperature span are defined by the ordered sensor option.

What temperature ranges are supported?

The supported range depends on the chosen sensing element and construction. Typical selections include mid-range RTDs (e.g., up to several hundred degrees Celsius) and extended-range RTDs (down to cryogenic temperatures in some configurations). Thermocouple versions follow the applicable thermocouple standard and selected type.

Which wiring options are available for RTD elements?

RTD wiring can typically be configured as 2-wire, 3-wire, or 4-wire, with single or dual elements available in some builds. If an integrated head-mounted transmitter is ordered, only one RTD element may be connected to the transmitter input depending on the configuration.

What thermocouple types can be configured?

Thermocouple versions can be configured in multiple standard types (for example, Type K, J, N, T, E, and others depending on the ordering code) with single or multiple junction arrangements available in some configurations.

What diameters are commonly available for the measuring inset?

Standard inset diameters are available in several sizes (commonly including 3 mm, 4.5 mm, 6 mm, and 8 mm), with additional variants such as sleeved tip designs offered for certain applications. The final choice should match the host sensor/thermowell design.

What lengths are available?

Multiple standard insertion lengths are available (covering a wide span from shorter builds through to long insertion lengths), and customer-specific lengths can also be specified. The correct length is determined by the host thermometer geometry and required immersion.

Can it be supplied without a transmitter?

Yes. TSA101 can be supplied without a transmitter, typically either with a ceramic terminal block connection or with flying leads, depending on the selected option. This is useful when the signal conditioning is handled externally.

Which output/communication options are available when a transmitter is included?

When ordered with an integrated head-mounted temperature transmitter, common output options include 4–20 mA (HART) and fieldbus variants (such as PROFIBUS PA or FOUNDATION Fieldbus), depending on the selected transmitter model and configuration.

Is it suitable for use in hazardous areas?

Hazardous area suitability depends on the exact configuration, approvals selected, and how the complete temperature assembly is installed (including the head, cable entry, and any integrated transmitter). Configurations may be available to align with common explosion protection schemes (for example intrinsic safety or flameproof concepts) when specified correctly.

What documentation and certification options can be specified?

Optional documentation can include material and inspection/certification formats aligned with EN 10204 (for example declarations or inspection certificates), as well as calibration documentation with selectable test points and temperatures, depending on the ordered options.

What does the grounded measuring junction option mean?

A grounded junction option (commonly used with thermocouples) means the measuring junction is electrically connected to the sheath. This can improve response time in some applications, but it may influence susceptibility to electrical noise depending on the installation.

What information is needed to correctly specify a replacement measuring inset?

To avoid mismatch, the key details are the host sensor series/design, sensing technology (RTD or thermocouple), element type (e.g., Pt100/Pt1000 or TC type), wiring (2/3/4-wire or number of thermocouples), diameter, insertion length, any transmitter requirement (and protocol), and any approval or calibration requirements. If you have the original device type code from the nameplate, it is the most reliable way to match the correct TSA101 variant.
