DESCRIPTION
Two channels of high-performance signal conditioning amplifiers for quarter, half and full bridge transducers. May also be used for RTDs, potentiometers, dynamic strain, voltage and voltage mode (ICP type) charge transducers. Each channel has programmable voltage or current excitation, autobalance, voltage and shunt calibration, differential instrumentation amplifier, eight-pole low pass filter and two buffered, ±10 Volt wideband or filtered analog outputs. A separate AC coupled input and current source accommodates dynamic strain and voltage mode charge transducers.
The eight-wire, shielded input has dedicated shunt calibration and remote sense inputs. With remote sensing excitation voltage is regulated at the transducer negating the effect of long cables. Signal conditioning is programmable. There is no need to change components, jumpers or switch settings, just reprogram the transducer type. Two calibration resistors may each be selected to shunt either a remote bridge arm or the bridge completion resistor. Voltage substitution enables calibrating the channel using a traceable standard. Gains are programmable from 1 to 5,000 with 0.05% resolution or using calibrated gain steps. The standard filter is a four frequency, eight-pole, Bessel with plug-in resistor modules determining frequencies. Optionally available is a programmable, 4-pole Bessel filter with 1 Hz resolution from 4 Hz to 1 kHz and 3 Hz resolution from 1 kHz to 10 kHz.
The 6120 is available in two configurations: The basic 6120 has 50 kHz bandwidth and the 6120HF has 100 kHz bandwidth. Optional 4-step shunt calibration using the remote connection.
