Frequently Asked Questions
What sensors work with XTR105?
The XTR105 supports 2-wire, 3-wire, and 4-wire RTD temperature sensors, as well as resistive bridge sensors (pressure, strain, load cells). It provides two matched 0.8mA excitation current sources for sensor biasing and built-in linearization for Pt100/Pt1000 RTDs.
What is the loop supply voltage range for XTR105?
The XTR105 operates with loop supply voltage from 7.5V to 36V. The minimum compliance voltage depends on the sensor and load resistance. For typical 250-ohm load with 24V loop supply, the device provides full 4-20mA output range.
How accurate is the XTR105UA?
The XTR105UA achieves ±0.05% maximum span error and ±0.005% typical nonlinearity. Combined with the precision excitation sources (0.5% matching), it delivers excellent measurement accuracy suitable for industrial instrumentation meeting standard process control requirements.
What is the difference between XTR105 and XTR106?
The XTR105 is optimized for RTD sensors with two excitation current sources and linearization. The XTR106 is designed for bridge sensors with an integrated instrumentation amplifier. Choose XTR105 for temperature measurement with RTDs, and XTR106 for pressure/strain bridge circuits.
