Universal signal conditioner

  • 07-Nov-2010 01:11 EST

With its built-in, high-precision dc and constant current supply, Dewetron’s DAQP-STG module enables direct connection of quarter, half, and full bridges as well as piezoresistive bridges, resistors, potentiometers, and Pt100 to Pt1000 sensors. The signal conditioner can also directly measure voltages to ±10 V. Higher voltages to ±200 V, thermocouples, and IEPE (ICP) or charge sensors are supported using modular smart interfaces. Primarily designed as a high-end bridge amplifier, the module meets all requirements for strain gauge/bridge sensors. It features 13 predefined measurement ranges from ±0.1 to ±1000 mV/V, but any other sensitivity can be programmed. For example, an unusual number such as 2.27 mV/V can be entered. This flexibility allows the engineer to make full use of the dynamic capabilities of the measuring system. The DAQP-STG’s flexibility makes it suitable for very exacting measurements, such as resistance from 25 to 100 kΩ, or for very fast thermocouple measurements with electrical isolation.
