Being a very progressive company LH Group Services mission is to maintain its ethics of quality, safety and reliability by constantly enhancing its engineering expertise and the company has now taken Testo monitoring technology on board.
If we take for example the rafts of diesel transmission units – DMUs – that
LH Group Services are contracted to overhaul then the Testo T176-T4 channel temperature data logger really comes into its own. The data logger offers four-channel temperature monitoring with external sensor connections, a robust design for optimum impact protection, parallel temperature measurement capability at up to four sites, and a single, one-button menu navigation and large memory.
A tangible example of the new system in action occurs when the rafts are carefully checked on state-of-the-art test beds and data can be downloaded for extra information via the Testo logger at the post-test stage. The main ongoing advantage occurs after the unit has been returned to the customer and LH Group Services is able to monitor the state of important functions out in the zzfield to give early warning of problems and to assist in continuing development of better and more efficient systems. Typically, cooling performance is checked by monitoring the temperatures of the coolant both in and out of the engine. It can then be seen if the cooling system is not working as it should be – due to debris in the radiator for example. The data can be checked and exchanged on an ongoing basis to identify situations such as excessive engine stress or damage before it develops into a serious matter.
Electrical supervisor Brian Minion takes up the theme: “The neat, slim design of the data logger means that it can easily tuck into minimal space on the control panel and when on a raft we fit two loggers then this gives us the added input of monitoring other temperatures such as hydraulic oil, lubricating oil and the temperature of the turbocharged air as well as collecting more information which is invaluable for the health of the raft. We now fit a Testo logger to every class 22000 DMU that we overhaul, and we are looking in the future to install them on other systems which whilst adding a stage to the project does pay back in terms of the benefits of the information that we get back. The multiple benefits for all concerned translate into a better quality and more accurate refurbishment for the customer plus maintaining a smooth continual dialogue. It takes only ten seconds or so to download the data onto an SD card. I can’t think of anything else so easy and effective. This is definitely the way ahead.”
