• Description

  The input range of the cost-effective amplifier is appropriate for sensitivities between 0.5 and 30 mV/V and is also suitable for semiconductor strain gage. The measuring amplifier itself is powered by voltages between 15 V and 30 V. Internally, the highly accurate, short-circuit protected sensor excitation voltage is generated and used to supply the sensor‘s measuring bridge.

  The analog output voltage can be set to a range from 0 to ±5 V or 0 to ±10 V. Alternatively, customer-specific settings are possible. DIP switches are used to set the input range. Fine adjustments and zero point setting are performed by means of multi-turn potentiometers that are mounted on the circuit board. The sensors are connected, and the auxiliary power supplied, through user-friendly screw terminals.

  The amplifier in the IP67 version can, if in fact necessary, be achieved by clamping, gluing, or with the aid of a cable tie. The open circuit board has mounting holes for easy assembly. The amplifier‘s limit frequency is 1 kHz.

  Various housing variants are available. For field use, the IP67 variant with PG screw connection or, alternatively, with an M12 connector on the output side is available. The pluggable version allows for quick and easy installation and removal. Since the sensor is permanently connected to the measuring amplifier, the measuring chain can be installed as a whole. For mounting the measuring amplifier in the control cabinet, we recommend the 2-channel, 3-channel, or 4-channel DIN rail version. For use in the laboratory or as an OEM product, the pure circuit board version can be selected.
