Preventive and corrective maintenance service

The instrumentation installed in the field is naturally subject to the wear of its mechanical parts, dirt and the drift of the quality of the sensitive elements. Therefore, constant maintenance is required, which keeps the instrumentation efficient, ensuring the conservation status of the system guaranteed at the time of installation, helps prevent the risk of breakdowns and reduces the costs related to a possible restoration of operation. Thus it guarantees the quality and continuity of the recorded data.

Furthermore, it is periodically necessary to update the firmware of the instrument and the software to keep it always at maximum performance.

LSI LASTEM offers preventive maintenance contracts with scheduled interventions aimed at verifying the state of the hardware and data quality and updating firmware and software.

Alternatively, the customer can choose the corrective action formula to which the Customer Service will respond for the resolution of any sporadic problem by including the intervention in the planning of activities.

The scheduled preventive maintenance contract may already contain the possibility of taking advantage of corrective interventions at advantageous conditions, in fact the intervention times and costs are defined in advance, speeding up the ticket opening process.

Preventive and corrective maintenance service

Highlights

  • verification of the state of conservation, cleanliness and stability of the mechanical parts. Over time, the mechanical structure can lose its stability, dirt can affect the quality of the data collected and more generally mechanical problems may arise. The technician assesses the structure and intervenes as much as possible, if an ad hoc restoration is required, he reports it. The technician provides thorough cleaning of the sensors and parts exposed to bad weather where dust and smog accumulate.
  • Check the power system. Solar panels and batteries can lose their efficiency over time without giving signs of malfunction, therefore specific measurements are required. Even medium power transformers can lose their safety requirements over time. The LSI Lastem technician checks these elements, indicating if replacement is necessary.
  • Check sensor operation and measurement quality. The LSI Lastem technician carries out a series of comparison measurements with certified instrumentation placed next to the present one. At the end of the test, if the data of the instrument to be tested has a deviation greater than the uncertainty of the verification process, the technician will report that the sensor is suspect or faulty. At the end of the operation, a test / calibration report is issued, complete with the results of the tests and indications of any suggested corrective actions.
  • Replacement of parts subject to normal wear. In some sensors, especially meteorological ones, some elements are subject to natural wear over time. Hygro-sensitive elements, filters, salts-gels, pads etc. must be checked and eventually replaced or reconditioned.
  • Verification and testing of local and remote communication, software update. Modems and LAN converters must be checked to ensure that data arrives correctly and consistently to the receiving system. The technician tries to update the communication and data management software in order to ensure the stability of the functionality and the more general safety of the system.
  • Creation of reports. At the end of the intervention, a report is issued with a description of all the operations performed and their outcome.
