FP-RTD-122

National Instruments FP-RTD-122 FieldPoint Three-Wire RTD and Resistance Input Module
Features

• Inputs for 100 and 1,000 Ω Platinum RTDs
• Built-In Linearization for Six TCR Values of RTDs
• Direct Resistance Measurements in 400 and 4,000 Ω Ranges
• True Three-Wire Compensation
• 16-Bit Resolution

The National Instruments FP-RTD-122 are known for their accuracy, repeatability, linearity, and long term stability. Each input channel of the FP-RTD-122 can be used to measure the platinum RTDs or to measure the resistance of the RTD or other resistive device directly. The inputs are all filtered against 50 or 60 Hz noise, both common mode and normal mode. The 3-wire compensation works with the most common RTDs and is more accurate than typical bridge techniques.
