• analytical measurement systems

Offline calibrations are available in Yokogawa’s many environmentally controlled calibration laboratories. All calibrations are performed to international standards and have full traceability.

Periodic maintenance
Yokogawa Technical Services can offer extensive periodic maintenance, including:

• I/O: checking and testing
• Zirconia oxygen analysers: cleaning and calibration
• pH systems: cleaning and calibration
• conductivity systems: calibration
• recorders: cleaning, lubrication and calibration
• flowmeters: electronic testing
• pressure transmitters: calibration
• temperature sensors: verification

Periodic maintenance can be customised to users’ individual requirements.

Commissioning and fault diagnostics
Yokogawa Technical Services employs a highly trained and skilled team capable of meeting all requirements for commissioning and fault diagnostics in all manufacturers’ instrumentation, distributed control systems and Fieldbus installations. Yokogawa’s vast experience in various industries offers the facility for performing expert fault diagnosis and producing reports and recommendations to the customer.

Technical support
Yokogawa Technical Services can offer technical support for all contract clients for product maintenance and engineering requirements.

Telephone support can be provided during normal working hours, or 24-hour cover can be provided if a contract is in place.

Partnerships
Yokogawa Technical Services has a twofold responsibility to the customer:

• to make the customer aware of services available that will enable production to be maintained throughout the year.
• to provide a high standard of maintenance service that meets all the needs of the customer whenever and wherever required.

The purchase, operation and maintenance of all instruments involve a pro-active partnership between the supplier and the end-user that remains in place for the lifetime of the instrumentation.

Bonded stock
Yokogawa Technical Services can provide the facility of bonded spares. In conjunction with the customer, the critical items are identified. These spares can be held in stock at the supplier or at site specifically for use on a specific installation. Critical spare parts may be the property of the end user or, on payment of a holding fee to the supplier, may be purchased for storage in a bonded stock area.

Yokogawa Technical Services bonded stock is kept in a dedicated secure air-conditioned room, with each costumer having a segregated area.

Lease instruments
Yokogawa technical services can offer lease instruments to provide a turn-round capability for instruments removed for calibration. These instruments can be used as rotational calibration instruments or as standby spares if required.
