INTELLIGENT POWER CONTROL – MICO Safeguarding machine up-time The power supply is the heart of every control cabinet. Advanced power supply systems have to be protected in a consistent and targeted manner
MICO monitors currents: Select a maximum individual current value for each channel and MICO will monitor this value. When the value is within the appropriate range the LED will be solid green. MICO indicates when current is approaching the maximum load: When 90% of the selected current load is reached the LED will flash green.
MICO detects overload: In case of short circuits, or if the load current exceeds the selected value, MICO switches off the affected channel and the LED will flash red.
MICO provides flexibility: Every channel can be manually switched on or off by pressing the button. When this happens the LED will be red.

FOR APPLICATIONS WHERE SAFETY IS A CONCERN: HIGH-PRECISION MULTIPLE SECTION POTENTIOMETER FOR INDUSTRIAL USE
As the exclusive UK distributor for Novotechnik, the German sensor and sensor systems specialist, Variohm EuroSensor presents the following application note on the new multiple section potentiometers. Conductive plastic potentiometers for position sensing are commonly used for automotive engineering and many industrial applications. They are inexpensive and offer great precision. And with more than 50 to 100 million wiper movements, the life expectancy of higher-end versions is suitable for even intense mechanical requirements. But the potentiometer technology is continuously advancing, as evidenced, for example, by the new, highly durable Multiple Section Potentiometers. With multiple channels, they are especially well-suited for applications requiring redundancy. section version of the proven precision potentiometer P2500, featuring up to six channnels concern. The combination of plastic resistive track and multi-pronged precious metal wiper, a sturdy full-metal housing, and the durable 6mm stainless steel shaft provide for a long service life free of contact issues. This potentiometer is offered with rotation angles of 120, 240, or 345 degrees and allows continuous mechanical rotation. And it is very accurate, featuring a resolution degree of 0.01 and a linearity of +/-0.3 %. Additionally, the channels are calibrated to be well synchronized with each other. The fact that the shaft is running on multiple ball bearings allows for high bearing loads; ambient temperatures of -40 to 100° C are acceptable. The maximum operating speed is 2000 rpm.

Calibrating Crimp Tools, Torque Wrenches and Weighing Scales All instruments and measurement tools drift over time requiring calibration. Standards and traceability are closely related. The latter refers to procedures and records demonstrating accuracy of calibrated measurments explains Ibrahim Ibrahim and Eddy Jones of calibrate.co.uk. To claim traceability, a calibration laboratory must document measurement procedures and calibration reports to provide evidence of traceability.
Crimp tools Connectors for electrical and electronic equipment are regulated by IEC TC 48, and UL486A. Crimping tools used within critical manufacturing processes must be calibrated in accordance with these standards. It pays to ensure the tool and dies are calibrated and maintained in a serviceable condition. Calibration should occurr annually or every 10,000 crimps. The tool should pass a pull test in accordance with BS EN60352.
Weighing scales Weighing scales may lose accuracy for a variety of reasons: wear and tear of mechanical components, and environmental factors. Typical scale calibration involves weighing various standard weights as shown in image 2 in separate repeatability, eccentricity and weighing indication error tests. A key test for centre of gravity, the eccentricity test, involves placing the object being weighed in the middle of the load the shape of the object to be weighed. The test determines how much this affects the indication on the scale by placement position. Beamex has a useful white paper on the subject of weighing instrument calibration.
Motorised testers are an improvement on manual testing with controlled speed, and avoid overstressing of the load cell. The UltraTest Mecmesin Advanced Force Gauge AFG 500N motorised test system (image 1) performs tensile and compression testing up to 500 N. Consistent test speeds ensure repeatability.

Torque Wrenches
Calibrating the calibrators
Torque wrenches are used where bolts must be tightened
A calibration tool may itself need calibration. For example, the Norbar torque wrench analyser is regularly subjected to manufacturer tests with different known torques generated by applying masses calibrated to produce forces at the known radius of an unsupported length calibrated beam.
equipment. where component failure could cause a serious accident, such as in vehicles or gas stations. the manufacturer. If the torque is lower than the nominated value, leakages or even disconnections may occur. If it is of a higher value, shear damage to the thread on fasteners of critical equipment may occur, leading to industrial accidents and injuries. The only sure way that proper torque is applied is to have the torque wrench calibrated.
Calibration is best left to experts, whether in-house or outsourced. In the former case, manual or non-automated testers may be the only option allowed by budgetary constraints to offset the cost of skilled operators. However, outsourcing takes a company’s calibration activity off the balance sheet.

British Engineering Experts Provide Ultra-Marathon Tests For Aircraft Parts An aerospace componentry dynamometer test rig that can run continuously for 3,000 hours and longer has been built by Automated Technologies Ltd, to its philosophy of using as many British-made components as possible. Among the key components are a TorqSense transducer, made by Sensor Technology and a variable speed drive made by Invertek. Automated Technologies is a design and engineering company which develops novel automated solutions, innovative product designs, prototyping programmes and solutions for process problems. Over its many years’ experience developing
new technologies for demanding clients in all the major sectors of industry, it has come to rely on UK manufacturing, as Chief Engineer Chris Baxter explains: “Building bespoke machinery and developing prototypes, as we do, is a very collaborative process. Quite often we need considerable support from our suppliers as we work through a knotty problem or two; sometimes this means an intense hour long engineer-to-engineer phone call, or a visit to their premises. It is hardly surprising that this is easier with local companies.”
