THE LOCK-IN AMPLIFIER EXPLAINED AND REIMAGINED
important methods used by researchers to characterise electronic materials. But electrical signals are often at very low levels and in the presence of noise. Because DC measurement instruments
M
cannot easily extract the signal from the noise, AC measurement techniques are often used. They can modulate the signal with a frequency to measure the signal in the presence of less noise. The lock-in amplifier can perform such a measurement and is one of the best methods for measuring amplitude and phase of AC signals. For these reasons, it is the instrument of choice for low-level measurements of AC signals. An application note detailing the new M81-SSM, available from Quantum Design UK &
Ireland, examines how the lock-in technology employed in the M81-SSM’s architecture deals with removing the effects of noise from the measurement. Find out more and download the application note here:

PRESSURE MAPPING INDUSTRIAL SIZE FOAM BLOCK
needed to glue together. Their process involved feeding a large foam block into a machine that loops the foam

block round, so the two ends of the foam block face each other. An adhesive was then applied. The two ends being pushed together for several minutes while the adhesive cures. XSensor’s pressure mapping technology was ideal for this application. Using a system
normally used for bed/mattress R&D applications, we were able to see, measure and record;
• Live pressure distribution over the contact area, including average, peak and low- pressure areas.
• The pressure/force applied over the entire surface. • If there was any decline in pressure being applied over time. The test was repeated several times with the ends of the foam block being cut
vertically and diagonally. This was to see if any change of cut would improve the contact area or pressure that could be applied. The customer was very pleased as they had not been able to make measurements
over the entire contact area, measure the pressure being applied or test the effectiveness of different cuts.

EARTH LEAKAGE PROTECTION- SAFE GUARDING YOUR INVESTMENT AND YOUR RESILIENCE
increasing complexity of electrical installations and the loads placed on them can lead to progressive faults, especially in the earthing circuit. Early detection of the increased insulation or development of an earth fault allows the prevention of tripping events, maintains continuity of supply and a resilient installation, be it for the coffee machine or the critical piece of plant for your client’s order. Frer manufacture a series of earth league relays for us on Type AC, A, F and B earth fault protection applications. The X...DX3 series earth leakage relays are designed to measure the leakage or unbalanced currents caused by conductors or appliances insulation loss, and to trip the relay contact if the set limits are exceeded, switching of the power supply to the defective system. All the relays in the series for any of the installation requirements (Type AC, A, F or B earth fault protection) offer the following features, such as real time clock, RS485 and data logging of the event, dependant on model. The MODbus interface makes it very easy to provide communication and early warning of a developing fault. The Frer range offers options for panel or DIN rail mounting. As a manufacturer of Core balanced CT Frer can match your cable/busbar sizes to a CT manufactured in a fast timescale.
