MR UK is part of the global CMR Group, which employs 700 staff


across eight global manufacturing sites, and provides a range of instrumentation, sensors and control systems for diesel engine power generation systems destined for use in the marine, defence, oil and gas and transportation sectors. The North East manufacturing operations of CMR UK has extended its electronic control panel test capability with the purchase of a new multi- function electrical safety tester – the Seaward HAL 104. The HAL 104 is said to combine the performance of a multi-function


production line safety tester with load and power factor measurement for component and assembly energy consumption and ratings assessments. Incorporating AC/DC Hipot


(flash/dielectric strength), the tester is able to perform load and power functional tests, insulation, ground/earth bond testing to 40A, load testing to 16A with leakage measurement to 20mA. For CMR UK the new tester is primarily


being used to provide HV dielectric testing and insulation resistance measurement on panel assemblies to endure electrical safety standards compliance with both BIS and IEC


Certification for enhanced FTIR emissions analyser


The CEMS II e continuous emissions monitoring system, from Gasmet Technologies, has completed EN 15267-3 testing using FTIR technology for the analysis of low range HF, low range NO, CH4 and formaldehyde which means that in addition to meeting performance specifications of European directives it also meets the more stringent specifications in the type approval standard EN 15267-3 for a larger number of components.


The test results for hydrogen fluoride were said to be good as, or better than, other FTIR manufacturers, but the data for nitrogen oxide and formaldehyde were significant, because no other FTIR is certified down to 150 mg/m3


NO, and no other instrument is approved for formaldehyde.


The performance tests involved laboratory and climate chamber tests and a field test of six months. They were carried out by TÜV Rheinland, an independent test, inspection and auditing organisation. While the field test was completed in 2015, an extended field test is still ongoing, and this will extend the maintenance interval of three months up to six months upon completion of a year of faultless operation. Rami Vuorinen manages Gasmet’s development work. He said: “During 2014, we were able to reduce the


baseline noise level significantly, improving sensitivity by a factor of two.” Gasmet Technologies Oy

‘SwitchSmart’ technology which combines conventional testing with a dedicated switching matrix to cater for three-phase circuits. This functionality has enabled CMR to connect to pairs of conductors successively in a three-phase system (L1, L2, L3 and Earth). The system software then follows an automatic procedure of testing for both dielectric withstand and insulation resistance using the switchsmart to channel the test voltage between different conductors to ensure good insulation between all phases and earth. The complete HAL package is driven by Safety e-Base Pro software, that allows fully customisable test sequences to be set up and operated via a PC from any safe and convenient location. The intuitive user-interface provides user prompts in both text and graphical format, saving time and reducing the risk of human error. Traceability is made possible by storing all results on a network drive.


Rick Charles, technical projects


manager at CMR said: “The new test instrumentation and expanded test capability provides exceptional levels of flexibility and functionality, which has dramatically improved the quality and efficiency of the panel assembly testing undertaken by the CMR technical team.”
