USEA Amplificador para sensores con salidas bajas en mV ó µV

• Amplificador Universal USEA: amplifica señales DC de sensores con salidas bajas en mV ó µV.
• Entrada µV ó mV: Salida amplificada para adecuarlo al rango de entrada del registrador.
• Factor de amplificación seleccionable por micro-switch: x2,5, 10, 1520, 50, 100, 200, 500, 1000, 1500.
• No requiere alimentación externa si es conectado a un registrador HOBO (especificar USEA/HOBO).
• Salida para canal externo de HOBO (0 - 2,5Vdc).

The Universal Single Ended Amplifier (USEA) is a two stage non-inverting amplifier, voltage input to voltage output.
It is optimized for amplification of low-level DC signals from transducers/ sensors.
Two internal jumper blocks that allow the user to select any one of ten gain settings ranging from X2 to X1500.
