Amplifier converts up to four strain
gauges
The SGA strain gauge amplifier is a compact yet rugged solution to conditioning the signals from up to four devices and transforming them into a choice of industry-standard analogue signals.
The SGA strain gauge amplifier, now available from Magna Projects and Instruments, is an extremely cost-efficient, flexible, and compact yet rugged solution to conditioning the signals from up to four strain gauge devices and for transforming them into a choice of industry-standard analogue signals The SGA is available as a DC-powered unit (SGA/D), and as a mains-powered instrument (SGA/A), though the latter version allows dual use of a DC power supply, for example to protect against mains failures

Magna Projects and Instruments Limited has been awarded an exclusive licence by the UK's National Physical Laboratory to manufacture and market NPL's PCV Pressure Coefficient of Viscosity apparatus
The SGA may be programmed to handled almost any type of strain-gauge based sensor with sensitivities between 0.1 and 30mV/V, and is provided with switchable low-pass filters to allow extraneous noise from, for example, mechanical vibration and electrical sources, to be eliminated from the signals over the frequency range 1Hz to 5kHz.
The excitation voltage for the strain gauges is built into the robust, surface-mount, single-board design.
The SGA allows simultaneous current and voltage outputs, and has user-selectable output ranges of +/-10V, +/-5V, 0-5V, 0-10V, 0-20mA and 4-20mA.
The output may be offset by up to +/-70% of full scale range.
The SGA has full CE approval, has a 3-year manufacturer's warranty, and is mounted in an IP65 ABS field case with cable glands.
The SGA units are available on short delivery times, and may be purchased via Magna's online shop.
The units are useful for research and development applications, for process control engineers, and for educational applications.
