Product Summary
The xtr105pa is a microcircuit, 4-20mA, two-wire transmitter containing a high accuracy instrumentation amplifier (IA), a voltage-controlled output current source, and dual-matched precision current reference. This combination of the xtr105pa is ideally suited for remote signal conditioning of a wide variety of transducers such as thermocouples, RTDs, thermistors, and strain gauge bridges. Applications of the xtr105pa include: industrial process control pressure transmitters, resistance bridge inputs, thermocouple inputs, RTD inputs, current shunt (mV) inputs, precision dual current sources, automated manufacturing and power/plant energy system monitoring.
