Product Introduction

The XTR101 is a microcircuit, 4 - 20mA, two-wire transmitter containing a high-precision instrumented amplifier (IA), a voltage-controlled output current source and dual matching precision current references. This combination is ideal for various remote control signal conditioning such as thermocouples, RTDs, thermistors, sensors and strain gage bridges. The state-of-the-art design and laser fine-tuning, wide temperature range operation, and small size make it ideal for industrial process control applications. In addition, the optional external transistor allows for even greater accuracy.

Two-wire transmitters allow signals and power to be supplied to a monofilament by adjusting the current of the power supply and the input signal source.
