The WIKA TR22-B resistance thermometer is used for temperature measurement in sanitary applications. For an integration into the process, the patented thermowell model TW61 is directly fitted into a pipeline using orbital welding. The connection ends are smooth and prepared for orbital welding. The process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring points. For easy calibration or maintenance, the sensor is removable without having to break into the process or disconnect the electrical connection. Thus hygiene risks can be minimised, and downtimes can be reduced. The spring-loaded measuring insert guarantees the contact between the sensor tip and the bottom of the thermowell and thus ensures a fast response time and high accuracy.

This WIKA TR25 resistance thermometer is used in applications where a thermowell immersed into the process medium is not possible or not desired, particularly for piggable pipelines, highly viscous media and flow conditions with high shear forces. A wide variety of process connections is available so that these thermometers can be used for many different processes without any problems. 3- or 4-wire platinum measurement resistances in accuracy classes A and B per DIN EN 60751 serve as sensors. Analog or digital transmitters built into the connection head are able of making multiple output signals available, for example, 4 … 20 mA, HART® protocol, FOUNDATION„¢ fieldbus or PROFIBUS® PA.

The SIKA TP M 255S temperature calibrator can be used everywhere, including on-site in workshops, test and measurement rooms as well as laboratories. The SIKA TP M 255S temperature calibrator covers a broad spectrum of industries with diverse applications. The optimum thermal coupling from the block to test item is achieved with the correct adapter sleeve. Ideally, the internal diameter of the sleeve is 0.5 mm larger than the outer diameter of the test item. With the aid of the adapter sleeve, straight temperature sensors of virtually any length and width can be calibrated. The dry block covers the entire temperature range without the need to change the calibration medium. Viscosity, flash points or outgassing are of no concern. Micro bath function The use of calibration liquids offers certain advantages if temperature sensors with an unusual shape and size are to be tested. The test item is immersed directly into the liquid without an insulating air gap, resulting in direct temperature contact between the calibrator and the test item. The liquid, such as silicone oil, is chosen depending on the calibration temperature required. The continuous adjustment of the magnetic stirrer together with the removable sensor basket agitates the calibration liquid to create a large measuring zone. Furthermore, the sensor basket guarantees unhindered stirring and helps protect the tank floor.

The SIKA TP3M 255E temperature calibrator can be used everywhere, including on site in workshops, test and measurement rooms as well as laboratories.

The dry block covers the entire temperature range without the need to change the calibration medium. Viscosity, flashpoints or outgassing are of no concern. Black body function A patented infrared calibration sleeve is used to calibrate IR pyrometers or thermal imaging cameras. The special surface structure and the asymmetrical shapes create a žcavity radiatorœ with an emission factor of 0.9994, prevent the reflection of interference radiation and emit the required temperature in an ideal form. The pyrometer is simply held at the specified distance above the measurement opening, thereby forming the desired measurement area on the bottom for the calibration to be performed. A support base can be fitted directly on the unit. Surface temperature function Surface temperature sensors are calibrated using special sleeves that are fitted vertically with the required contact force. Switching the SIKA TP3M 255E temperature calibrator control to the external reference sensor creates the best possible temperature reference point on the surface of the sleeve. The reference sensor is located directly beneath the abutting face of the sleeve. The sleeve is designed in such a way that the best temperature homogeneity is achieved in the centre of the abutting face. The special design of the abutting face enables good thermal contact. There is no need to use a thermally conductive paste or other thermal conduction aids.
