Description
Four high-performance, fully programmable signal conditioning amplifiers for quarter, half and full bridge. Each channel has programmable excitation, autobalance, voltage and shunt calibration, differential instrumentation amplifier, low pass anti-aliasing filter and sample and hold amplifier. High-level outputs are multiplexed to a 16-bit ADC.
Individual excitation regulators with remote sensing make the 6032 ideal for use with long input cables. Using remote sensing excitation voltage can be set and regulated at the transducer. An eight-wire, shielded input has dedicated shunt calibration leads or internal shunt can be selected. Excitation voltage can be measured during calibration or the optional excitation monitor continuously digitizes and samples the excitation for each channel. The standard filter is an 4-pole, Butterworth with plug-in frequency selection. Optionally available is a programmable, 4-pole Butterworth filter with 10 frequency steps per decade. Each channel has a continuous analog output.
Specifications Model 6032
| Input | Two to eight wires with shield with programmable completion for 120 and 350 Ohm quarter, half and full bridge transducers. Input connector is 50-pin Type D Subminiature. |
| Excitation | 0 to +12 volts in 1 ±0.1% Volt steps, 50mA individually set and regulated for each channel. Stability is ±0.01%, line and load regulation are ±0.01% using remote sensing. Calibration mode measures excitation voltage using the amplifier. A short on one channel does not affect other channels. |
| Excitation Monitor (Option EM) | Supplemental channel measures excitation using 16-bit ADC, 0.1% accuracy. Dedicated alarms may be used to automatically detect excitation error. |
| Balance | Automatic to ±0.05% of range ±1mV. Stability is ±0.01%, ±0.005%/°C. User adjustable balance range. |
| Input Range | ±2mV to ±10 Volts full scale. Input protected to ±50 Volts. |
| Calibration | Voltage substitution with attenuation of 1, 0.1 and 0.01. Singe-step resistive shunt calibration. Shunt calibration may be applied to external gauge arm or internal completion resistor. |
