1 Electrical Temperature Measurement In-Line Resistance Thermometers Model TR25 WIKA Data Sheet TE Applications Food and beverage industry, dairies, drink dispensers and bottling plants, breweries Biotech and pharmaceutical industrie, paint/varnish industry, clean room technology Special Features Hygienic design (dead space free transitions) Residue free and quick cleaning of the measuring point (piggable, for SIP and CIP) Materials and surface qualities in accordance with the standards and directives of the pharmaceutical industry High measuring accuracy with short response times Explosion-protected versions Ex-i In-Line Resistance Thermometer Model TR25 Description Resistance thermometers for temperature measurement in processes with extremely high hygienic requirements. These thermometers are used in applications where a thermowell immersed into the process medium is not possible or not desi. A wide variety of process connections is available, so that these thermometers can be used for many different processes without any problems. Analogue or digital transmitters built into the connection head are capable of making various output signals such as ma, HART protocol, Profibus PA or FOUNDATION Fieldbus available. 3- or 4-wire platinum measurement resistances in accuracy classes A and B per DIN EN serve as sensors.

2 Sensor 1 x Pt100 with 3- or 4-wire connection. The standard temperature range is -50 C C. Note: The instrument does not have an exchangeable measuring insert. Sensor limiting error Class B per DIN EN Class A per DIN EN Basic values and limiting errors Basic values and limiting errors for the platinum measurement resistances are laid down in DIN EN The nominal value of Pt100 sensors is 100 Ω at 0 C. The temperature coefficient α can be stated simply to be between 0 C and 100 C with: α = C -1 The relationship between the temperature and the electrical resistance is characterised by polynomials which are defined in DIN EN Furthermore, this standard lays down the basic values in C stages. Class Limiting error in C A t 1) B t 1) t is the value of the temperature in C without consideration of the sign Basic values and limiting errors for the platinum measurement resistances per DIN EN Ω Temperature Basic value Limiting error DIN EN (ITS 90) Class A Class B C Ω C Ω C ± 0.25 ± 0.10 ± 0.55 ± ± 0.15 ± 0.06 ± 0.30 ± ± 0.25 ± 0.10 ± 0.55 ± ± 0.35 ± 0.13 ± 0.80 ± ± 0.45 ± 0.17 ± 1.05 ± 0.39 Documentation / Optimisation of the measuring deviation The measuring deviation of these thermometers can be determined under close to real process conditions and supplied with a certificate. The standard testing temperature is 70 C, others on request. If a digital transmitter is mounted into the thermometer, a determined measuring deviation can be corrected using the adaption feature of the transmitter configuration software. Materials In sterile processes mainly austenitic CrNiMo steels are used as standard materials. In the food and beverage sector and in the pharmaceutical industry the qualities and are to be prefer to the titanium-stabilised steel (AISI 316Ti). For these thermometers WIKA uses stainless steel as standard material for all metallic surfaces that may come into contact with the process medium. Error in C Class B in C Class B in Ω Class A in C Class A in Ω Temperature in C Error in Ω Surface The possibility of cleaning a plant in the scope of CIP/ SIP processes is mainly influenced by the quality of the surfaces in contact with the process medium. In order to avoid concentration of pathogenic organisms, the surface in contact with the product should be passive and free of microscopic faults. All model TR25 surfaces that may come into contact with the process medium achieve an average surface roughness of R a 0.8 µm. On request we supply the surfaces exposed to the product with following finish: 0.8 µm (standard) 0.4 µm 0.4 µm electropolished 0.25 µm mechanic- and electropolished Page 2 of 8 WIKA Data Sheet TE /2009

Standard neck lenght N (M H ): 50 mm Standard diameter d: 12 mm In many applications the neck tube is also used as a part cooling element between connection head and medium in order to protect any head mount transmitters from high medium temperatures.

The connection head used in this case is similar to the head model BSZ-H. For operation a ma transmitter is necessary, which is mounted to the measuring insert. The scale range of the indicator is configu identical to the measuring range of the transmitter. Intrinsically safe versions, explosion protection type EEx (i), are also available.

8 Explosion protection (option) Model TR25 resistance thermometers are available with a type examination certificate for intrinsically safe protection (TÜV 03 ATEX 2233 X). These thermometers comply with the requirements of directive 94/9/EC (ATEX), Ex-i, for gases and dust. Built-in transmitters have their own approval. The permissible ambient temperature ranges of the built-in transmitters can be taken from the corresponding transmitter approval. The classification / suitability of the instrument (permissible power Pmax., minimum neck length and permissible ambient temperature) for the respective category can be seen from the type examination certificate and the operating instructions. Electrical conenction 1 x Pt100, 3-wire 1 x Pt100, 4-wire Modifications may take place and materials specified may be replaced by others without prior notice.
