  1. Do you account for gravity when using a Deadweight Tester or Piston Gauge?

    Gravity varies depending on where you are around the world, up to approximately 0.5%. Local gravity correction is typically the largest environmental influence acting on the deadweight tester. When you are carrying out calibrations in your laboratory or on-site the local acceleration of gravity, where the pressure calibrator is being used, needs to be accounted for to ensure calibration accuracy...
  2. Spot the Signs and Symptoms of Power Quality Faults

    On the left white text on a black background reads 'Info Guide: Spot the Signs and Symptoms of Power Quality Faults'. On the right, a man wearing a red helmet with a face shield, white balaclava, blue overalls, and white protective gloves is using a Fluke 1770-Series Power Logger hanging on a green metal door to inspect a system. Power quality problems aren’t always immediately recognisable. Without power quality monitoring, issues within electrical distribution systems and/or faults with equipment may be misdiagnosed as, for example, an old breaker that needs to be replaced. Misdiagnosis could lead to ineffective 'corrections', for instance, resetting the equipment or circuit. Spotting the signs of power quality issues early is essential to prevent further damage to systems or equipment. Once symptoms have been recognised, you can use a power quality analyser, such as Fluke’s 1770-Series Power Loggers, to monitor loads, voltage, current, harmonics, and unbalance or disturbance patterns.[1] Continue reading →

  4. Seaward Apollo 600+ Case Study: Oxfordshire City Council

    Oxfordshire City Council commissions ODS (Oxford Direct Services) to maintain council properties including 7000 residential homes, as well as parks and streets across the county. To fulfil such an important, varied, and large-scale contract, ODS employ a team of over 200 builders, plumbers, electricians, and other skilled tradesmen to conduct maintenance and repair work. Staff use company equipment, therefore, to ensure their safety ODS has implemented a preventive maintenance program. As part of this program, Seaward equipment, such as the Apollo 600+ with PATGuard 3 Software, is used to check the electrical safety of company equipment including drills, portable lighting, vacuum cleaners, heaters, compressors, and batteries.   Continue reading →
  5. Seaward Apollo 600+ Case Study: London Underground

    London Underground is one of the world’s largest underground passenger railway networks operating a system of 11 train lines, 270 stations, and 250 miles of track covering Greater London and parts of Hertfordshire, Buckinghamshire, and Essex. Serving over five million passengers a day, London Underground must ensure all its in-service items meet electrical safety requirements. They have been a long-time user of Seaward’s PAT testing equipment and currently employ 12 Seaward Apollo 600+ PAT Testers with PATGuard 3 Testing Software to verify tens of thousands of items across 500 sites.

  6. Super-Deduction Tax Relief: Claim 130% Capital Allowances on Plant and Machinery

    In a bid to stimulate business investment, promote economic growth, and aid with recovery in the wake of COVID-19, the UK government has introduced a super-deduction tax relief scheme, amongst other capital allowances. The temporary super-deduction program provides an alternative to traditional writing-down allowances. It will enable businesses to claim 130% first-year relief on qualifying plant and machinery investments between the 1st April 2021 and the 31st March 2023. Under this measure, businesses could save up to 25p in tax on every £1 they invest in eligible equipment.[1] Continue reading →
  7. Tech Tip: Druck Explains How to Calculate Loop Transmitter Systems’ Requirements & Limitations

    Transmitters emit current loop signal outputs of 4 to 20mA. Industrial systems often utilise transmitters with 4 to 20mA sensor signals because they provide noise immunity, support use with long cable lengths, and require only two-wire connectivity. However, if all the factors of a loop transmitter system are not taken into account the system could fail or have limited functionality. Fortunately, Druck has produced a paper that offers instructions and tips on how to calculate the requirements and limitations of loop transmitter systems. Continue reading →

  9. FLIR Offers FREE Training for Skin-Temperature Screening

    FLIR has provided a series of FREE short video tutorials (available below) to aid businesses, organisations and screening staff with conducting accurate and reliable skin-temperature checks using FLIR Exx- and T-series Thermal Cameras. These thermal imaging cameras can be installed at building entrances, ports of entry and checkpoints to screen individuals for elevated skin temperature. EST can be suggestive of a fever which is a common symptom of many illnesses including COVID-19.[1] Therefore, these FLIR Exx- and T-series Thermal Cameras can be used alongside other social distancing and hygiene measures to help prevent the spread of infection in public and professional places.

  10. How to Use Handheld or Tripod-Mounted Thermal Cameras for EST-Screening

    As the UK slowly begins to emerge from lockdown, with pubs, restaurants, hairdressers and some leisure facilities and tourist attractions able to re-open in England from the 4th July 2020 (provided they follow COVID Secure Guidelines)[1], it is important that social distancing and hygiene measures are implemented to prevent the potential spread of coronavirus. Skin-temperature-screening thermal imaging cameras offer an innovative, efficient and simple solution to detecting individuals who might have a fever, which is a common symptom of COVID-19.[2] They can be used to conduct non-contact temperature-screening at building entrances.
