Обзор

The innovative and improved clamp-on temperature measurement system offers measuring features that were previously only achievable using inline techniques.

• For pipe diameters of 4 to 57 mm (0.16 to 2.24 inch), optionally up to 200 mm (7.9 inch)
• Replaceable measuring insert
• All common output signals
• Intrinsically safe Ex versions
• Hygienic design acc. to EHEDG

Область применения

The innovative clamp-on temperature measuring system is primarily used for temperature monitoring and process control in the food and pharmaceutical industries, and in sterile applications in particular.

It completely replaces the commonly used inline measurement system, without having any of the inherent disadvantages: opening of pipelines during assembly, high costs for assembly and qualification of welded connections, flow and hygiene problems.

Особенности

• Fast response times and high-precision
• Temperature measurements with no dead spaces, turbulence-free
• Decoupling of ambient temperature influences, errors in measurement approx. 0.2 %/10K
• Can be recalibrated
• Cost savings during installation and operation No welding in, easy to dismantle for recalibration

Дизайн

Temperature measurement is carried out over a modified and quick-response Pt100 measuring element, which is positioned and insulated over a pipe collar made of heat-resistant plastic.

The measuring insert contains a special temperature sensor made of silver, which is pressed evenly onto the pipeline by means of a spring.

The positively drive operation of the replaceable measuring insert ensures even pressure contact on the pipeline, which in turn ensures a reproducible measuring result.

Интеграция

The device either provides the Pt100 sensor signal direct or, in the version with connection head for mounting on the transmitter, the standard signals 4 to 20 mA as well, HART, PROFIBUS PA and FOUNDATION fieldbus. This ensures easy integration in an existing device concept.

Конфигурация

In order to ensure selection of the right device, it is necessary to know the pipe diameter of the metering tube. For special sizes, first select the correct collar size and specify the required size in plain text. Space-saving versions for narrow installation conditions (e.g. pipe bundles) are also available (latch-fastening version).

The required output signal can be selected, as described under "Integration". The cable gland for the stainless steel enclosure may vary from the standard version. There are a range of intrinsically safe versions available for explosion protection acc. to ATEX, both for gases and for dust. For the correct assignment after recalibration, both the collar and the measuring insert are marked with the serial number and pipe diameter. These data can also be engraved if required. Furthermore, customers can select the setting for the transmitter, a TAG marking and the option of 4-wire circuit.

We recommend using thermo-lubricant.

Програмирование

PROFIBUS PA versions are coupled to the bus and set using the SIMATIC PDM operating software. FOUNDATION fieldbus devices are set over AMS. The HART version can be configured over a handheld or over a HART modem in conjunction with SIMATIC PDM or AMS.

For 4 to 20 mA devices without HART protocol, a special modem and the SIPROM T operating software is required. We recommend using the USB version of the modem. The USB interface also provides the power supply.
