Temperature is the most frequently measured parameter in the process industry. In electrical, contact thermometers two measurement principles have asserted themselves as a standard: RTD - Resistance sensors A thermocouple is a component made of two different metals connected with each other at one end. An electrical potential (thermoelectric force) is caused due to the Seebeck effect at the open end if the connection and the free ends are exposed to differ- ent temperatures. With the help of the so-called thermocouples reference tables (see IEC 584) the temperature at the connection...

The process connection is the connection between the process and the thermometer.The following process connections are those most commonly used in the process industries: Compression fitting: The thermometer is put into a sleeve in the compression fitting and then clamped using either a reusable compression ring or destroyed olive. The compression fitting is either screwed or welded into the process. Flange: Flanges are subject to the DIN or ANSI / ASME standards. They are classified according to material, diameter, hole pitch and pressure rating.To fulfill the strongly varying process...

The task of transmitters is the transformation of the sensor signal into a stable and standardized signal. In the past, transmitters were built using analog technology. In the meantime digital technology has gained acceptance, however, because it offers better measure-ment accuracy at simultaneously higher flexibility. In addition, digital transmitters allow a greater ambient temperature range typically between -40 C and +85 аC.Transmitters are typically offered in three distinctive types of housing: As DIN rail mounted devices suitable for panel installation. Օ As head transmitters for...

Typical processes in the food & pharmaceutical industry demand special functions such as fast response times and high accuracy of temperature measurement. The process temperatures in food processes are in the range of -40 C and 250 аC and between -50 C and 400 аC in pharmaceutical processes. Process pressures can be anywhere between atmosphere and 100 bar.Furthermore an important prerequisite is a hygienic design capable of cleaning in process (CIP) and sterilization in process (SIP). > Connection head Metric-style: Stainless steel housing, hygienic and easy to clean.

In glass smelters, flue gas applications and in the brick and ceramics industries temperatures up to 1700 C can occur. This requires special thermometers with ceramic thermowells and thermocouples made from special metals, such as platinum and rhodium. The ceramic thermowell external and sandwich coatings act as diffusion barriers. They serve as protection of the measurement point from mechanical and chemical damages in the process, e.g. from abrasive gases. The ceramic thermowell inner sheath is the ceramic capillary. It has the purpose of feeding and insulating the thermo wires. A higher...
