Temperature sensors are subject to mechanical, thermal and chemical stress. This results in a drift the longer the sensors are in use. Only the regular calibration of the sensors provides information on the difference between the actual temperature and the measured temperature and makes the specific drift visible.
Dry block calibrators and micro calibration baths are used to check and calibrate a wide range of temperature measuring instruments and temperature sensors. Mechanical, electro-mechanical or electronic measurement equipment can be checked with ease. The compact and robust SIKA instruments are easy to transport, simple to use and offer all the features required for the specific test.
A temperature calibrator needs to meet a wide range of requirements: as a portable device, it has to cope with frequently changing operation locations in the test bay or in production, while being equally suitable for stationary use in the measuring workshop and testing and inspection laboratory. For this reason, the instruments must be lightweight and handy for quick and easy use on site. SIKA offers several temperature calibrators to cover the range from -55 °C to 1300 °C.
The following can be tested directly:
The TP Premium series stands for optimum performance and outstanding ease of use. With the help of the self-explanatory menu structure, all the necessary entries can be made quickly and easily. The block and set temperature, as well as the difference and the variance of the stability, are displayed on the touch display. The block temperature can be set to precisely 0.001 °C. The entire thermosensitive range of temperature sensors is covered. The calibrators work in a temperature range up to 650 °C, while offering excellent stability and accuracy. By combining the dry block design with an input for an external reference sensor, SIKA calibrators have the same accuracy as laboratory calibrators while maintaining the speed and portability of a dry block. The temperature sensor under test can be connected and analysed directly. Additional instruments are not required. Together with a PC as a standalone calibration system, the result is an extremely quick test cycle
Dry block function
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 diameter 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.
SIKA temperature calibrators can be used everywhere, including on site in workshops, test and measurement rooms as well as laboratories. They cover a broad spectrum of industries with diverse applications.
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.
