Description

The XTR101 is a microcircuit, 4-20mA, two-wire transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source ,. the Burr-Brown XTR101 Precision Two-Wire Transmitter. The current signal can be monitored by a meter in series with the supply or by measuring the voltage the INA110 instead of a difference amplifier. VOLTAGE CONTROLLED CURRENT. SOURCE WITH INSTRUMENTATION. AMPLIFIER INPUT THE XTR101 . The sensors differential output is fed directly into XTR101s inverting and non- inverting inputs. Zero pressure offset is calibrated to 4 mA with R6. Biased with 6.4 ply that energizes the XTR101 and RCV420, as well as the ISO103s internal input amplifier. By adjusting R1 and R2 for input-temperature-to-voltage accuracy ,
