What is calibration? 

Calibration is the comparing of a measurement instrument against the reference instrument. The reference instrument is the ‘standard measurement’ and is taken to be the correct value of the two in comparison. Yokogawa Technical Services offers calibration across a wide range of instrumentation and guarantees the highest accuracy and traceability to international standards. In the event that the measured instrument proves too inaccurate for its required duty, Yokogawa can provide re-calibration or replacement of the instrument, whichever corrective measure is most appropriate. 

Why do users need calibration?
As equipment becomes more complex and schedules more demanding, users need to maximise plant efficiency and return on assets. Maintaining the accuracy of instrumentation through timely and consistent calibration plays an essential role in achieving these objectives.

All Yokogawa’s calibrations are traceable, providing assurance to users for the safe and efficient running of their plant. Calibration certificates are supplied for all instrumentation tested, with details of the test equipment used. All Yokogawa’s reference instruments are certified annually.

This includes:

  • Analogue gauges
  • Static pressure transmitters
  • Differential pressure transmitters
  • Differential pressure transmitters for high static pressure processes
  • Field calibrators

Temperature 
A range of temperature calibration facilities includes RTD and thermocouple inputs across all ranges using traceable injection equipment and controlled heat baths between -20 and 650°C on and off site. Calibrations can be performed on Yokogawa instrumentation such as recorders, controllers, temperature transmitters, RTDs and thermocouples. 

Flow 
With a state of the art gravimetric calibration facility, Yokogawa can accommodate many flow meter variants with calibrations between 0.95 and 6623 litres/min and process connections up to 200mm in diameter.

Yokogawa provides a comprehensive critical spares holding and repair service, including:

  • Bonded Stock
  • Lease Spares
  • Rotational Calibration Spares
  • Hot Spares

Yokogawa endeavours to provide not only a spares service, but a complete service solution, where in-house experts ensure that the transfer of parts and implementation of repairs are up to and beyond customer expectations. Spares are held to the customer’s specific requirements, whether local to the site or held by Yokogawa. All Yokogawa Technical Services spares are held in a dedicated secure and climate-controlled area, with each costumer having a specific section.

Bonded Stock

Yokogawa Technical Services can provide the facility of bonded spares. In conjunction with the customer, critical spare parts are identified. These spares can either be held in stock at Yokogawa UK or on site specifically for use on a single system. These critical spare parts may be the property of the end user; alternatively, customers may pay a holding fee to Yokogawa to purchase and store the spares in a bonded stock area.

Lease Spares

Yokogawa can also offer lease spares to be used on a standby/spare basis or to the customer’s specific requirements. These spares can be held local to site or at Yokogawa’s dedicated facility.

Yokogawa Technical Services offers a hire service that provides pre-configured instrumentation for a ‘plug & play’ solution. The wide range of equipment available covers everything from paper recorders, through analytical equipment, to BRAIN and HART terminals. It is possible for users to hire on a short-term basis while equipment is being repaired, and telephone support is provided at no extra cost. All equipment is available on short notice with overnight delivery, and can be hired on a daily, weekly or monthly basis.

Controllers
With discrete controllers running smaller production areas and dedicated batch plants, a failure can have a huge impact on production, potentially incurring a high cost or holding up the next step of an important process. Yokogawa offers a wide range of controllers for hire which may be utilised for a short-term control solution or as direct replacement whilst a failed unit is repaired.

pH Equipment
pH analysers can be pre-configured ‘in-house’ to enable direct replacement. The customer can then plug in the hired unit and continue to monitor or control the plant in as short a time as possible. This reduces any unforeseen environmental issues or ‘out of spec’ product problems while instruments are undergoing test or repair.

Conductivity equipment
Conductivity units can be pre-configured before dispatch to site, reducing installation time and eliminating problems with initial setup. All units can be pre-calibrated to cover the desired ranges required by the customer for their process

Communication devices
With the most common forms of intelligent instruments now being programmable in-situ,  Yokogawa offers the hire of BRAIN and HART communicators on a weekly basis. These communicators enable technicians to commission, calibrate and perform on-site range changes with minimal or no down time.

Calibration equipment
Yokogawa can provide calibration equipment to assist instrument setup and commissioning. For example, the Yokogawa CA100 can provide loop or passive injection, input measurement, mA, mV, V, resistance and different thermocouple inputs, giving an all-in-one solution to commissioning and calibration needs. The unit comes with a traceable calibration certificate for audit trails.
