Thermocouples (TLSC)

We supply thermocouples and resistance temperature detectors (RTD's) in accordance with widely recognized standard configurations. Additionally, if our clients have specific needs, we create and provide customized structures that align with their intended usage. The following presents an outline of our product arrangements.

TLSC1

Structure featuring a threaded process connection and terminal head, designed for supply purposes. This apparatus is adaptable for provision with either a transmitter mounting plate or a ceramic terminal block. A diverse selection of terminal heads can be chosen from (see page 18 for options). This configuration offers the flexibility for installation within a thermowell or directly into the process utilizing an adjustable or fixed fitting mechanism.

This serves as an industrial-grade thermocouple sensor designed to cater to a variety of applications. It is offered in Type J, K, N, T, and can also be provided in other grades as per specific requests. The thermocouple is composed of fixed inserts with varying diameters, accompanied by a choice of either a transmitter mounting plate or a ceramic terminal block. The crucial hot junction within the thermocouple can be configured as either "grounded" or "ungrounded" from the protective sheath.

This product line encompasses a diverse selection of terminal heads, allowing for flexible customization. Installation options for the thermocouple include fitting it into a thermowell or directly integrating it into the industrial process through the use of adjustable or fixed fittings.

TLSC2

The design features adaptable extensions and, for thermocouples, swift detachable connectors and ports (if desired). The configuration can be integrated within a thermowell or directly into the operational setup using a modifiable compression fitting.

This thermocouple sensor, designed for industrial applications, is available in Type J, K, N, T, and other grades upon request. It offers a range of insert diameters and sheath materials to suit diverse needs. The thermocouple can be supplied with flexible tails, a quick disconnect plug, or a combination of both, allowing for flexible installation options.

The positioning of the hot junction is adaptable, with the choice of either a "grounded" or "ungrounded" configuration from the sheath. This flexibility caters to different measurement scenarios. The thermocouple's integration is further enhanced by its compatibility with either a thermowell or direct installation into the process through an adjustable compression fitting.

Particularly valuable in the ferrochrome industry, these thermocouple assemblies excel in measuring temperatures, especially in environments requiring lengths exceeding 15 meters. Their robust design is well-suited to tackle challenges posed by molten metal splashing.
