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:
- Contact-based immersion or surface temperature sensors
- Sensors with special shapes and sizes
- Non-contact infrared instruments and thermal imaging cameras
Series TP Premium
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.
Series TP Solid
With the temperature calibrators in the TP Solid series, the emphasis is on flexibility. Operation is easy, intuitive and allows fast access to comprehensive functions. In addition to dry block calibrators, micro calibration baths are also available to complete the portfolio. These baths are used as liquid bath calibrators with a magnetic stirrer that is controlled by rotary speed. Reversible functions combined with an external reference sensor make it possible to test different temperature monitoring equipment without regard to shape, size or measurement method. A changeover switch allows users to change easily between the internal and external reference. All instruments in this series are equipped with a serial PC port.
Series TP Basic
The temperature calibrators in the TP Basic series have been developed for direct on-site use. With these instruments the focus is on efficiency and portability. 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. Some of the dry block calibrators have a large 60 mm block borehole and can hold several test items at once.
We supply a wide range of accessories for our dry-block temperature calibrators and micro-calibration baths. These include matching pot seals for optimum thermo-coupling between block and test object in dry-block function, or our patented infrared calibration sleeve for calibrating IR pyrometers and infrared cameras. Our range of accessories extends to surface calibration sleeves, calibration fluids, calibration reference sensors and a beaker insert.
Scanner device TT-Scan
Resistance thermometers, thermocouples, temperature transmitters and switches must be calibrated using an instrument that measures the output signal and displays it as a temperature. Checking groups of temperature sensors can be automated by extending your SIKA calibrator with a TT-Scan unit and calibration software. Up to eight test items can be checked at the same time with this arrangement. The configuration of the test item type is free programmable. A reference sensor can be connected. The TT-Scan unit has a USB port for connection to a PC. SIKA calibration software analyses the measurement data and presents the results in graphic or tabular form. At the same time it automatically generates up to 8 certificates, which may also include customer data.
