Uninterrupted mobile calibration gets you up and running in record time

Calibration always results in an interruption of the process. On-site service and calibration from WIKA minimises the impact of these interruptions, and gets your processes back online in record time.

WIKA South Africa operates three mobile calibration vehicles that are equipped for pressure and temperature calibration in Gauteng, Eastern Cape and Western Cape provinces.

The company’s Namibia operation also operates a mobile calibration vehicle that can offer a 3.1 certificate for pressure and temperature calibration.

The vehicles are all air-conditioned for temperature and humidity control, which is recorded by a data-logger. The vehicles are plumbed for external power connection, but also have generators for back-up power.

If there are more than 10 items to be calibrated, then on-site calibration becomes an attractive alternative and has several advantages. Aside from the greatly reduced out-of- service time, there are also no freight charges for the instrumentation. With a technician on site, small repairs are also possible for instruments that

DID YOU KNOW?

WIKA’s vehicles in Gauteng and Western Cape are also ISO 17 025 accredited for pressure and temperature. The Eastern Cape vehicle will be upgraded to SANAS status as the need for this type of certification increases in the region. All of the mobile calibration technicians are MetCert certified metrologists.

would otherwise have to be replaced. For sensitive instruments, there is always the risk that they would be damaged in transit.

ACCREDITATION

The WIKA vehicles in Gauteng and Western Cape are also ISO 17 025 accredited for pressure and temperature. The Eastern Cape vehicle will be upgraded to SANAS status as the need for this type of certification increases in the Eastern Cape. All of the mobile calibration technicians are MetCert certified metrologists.

MEASURING RANGES

WIKA South Africa’s mobile calibration equipment covers pressure ranges from -1 bar to 700 bar, and temperature ranges from -20°C to 550°C.

CALIBRATION CYCLES

The question often arises as to how often instruments should be recalibrated. Of course the individual installations and applications have a great deal of influence on this, but instrument manufacturers recommend a calibration cycle of one year. WIKA is quite happy to assist customers in developing a re-calibration protocol.

WORLD-CLASS CALIBRATION EQUIPMENT

WIKA’s fixed and mobile calibration facilities

Janusz Luterek

make use of the best-in-class calibration equipment. Mobile pressure calibration is facilitated by the Mensor CPG 2500 reference standard which has an accuracy of 0.01% of full scale.

Pressure generation is handled by the CPP1200-X Hydraulic Comparison Test Pump. Temperature calibration is done using the CTB9100 oil bath or the CTD9100 dry-block calibrator. Temperature measurements are performed using the CTP2000 Standard Thermometer or the CTP5000 Reference Thermometer. Climate control is recorded using the CPU6000-W weather station. All of these items are available for purchase from WIKA.

All WIKA metrologists are not only all experienced calibrators, they also have a lot of insight into best-practice methods for instrument installation and are ready to share this experience. •
