LCM Systems has introduced a series of analogue strain gauge amplifiers that are suitable to measure force and weight. The multi-purpose sensors are suitable for OEM applications. The company also ensures calibration free of cost upon purchase of any of its load cells with the SGA range.
One of the main features of the SGA range is the very stable bridge excitation combined with the amplifiers’ flexibility. The 110/230V ac-powered SGA/A and the 18-24V dc-powered SGA/D ensure 10 or 5vdc on-board excitation. They can power up to 4x350Ù strain gauge bridges. They can also be customized upon request.
It is possible to amplify any sensing device that displays an input sensitivity of ±0.06 to 29mV/V to provide ±10V, ±5V, 0 to 10V, 0 to 5V, 0 to 20mA or 4 to 20mA outputs. A combination of switches used with a potentiometer provides an offset of ±70%FS. Filtering could take place from 1Hz to 5 kHz. The devices are available in IP65ABS field housing with cable glands. The system is ideal for larger instrumentation infrastructure. They can also convert signals of load cells prevailing in applications using long cables.
