2 Wire RTD - Pt1000 (Platinum 1000 Ohm) Probe Design

2 Wire RTD - Pt1000 (Platinum 1000 Ohm) Probe Design

2-Wire RTD Probes with Pt1000 (Platinum 1000 Ohm) with Class A Accuracy Temperature Sensing Elements.

    • Pt1000 RTD temperature sensing element design helps resolve the limitations
      2 Wire RTD Pt1000
      associated with the accuracy and self heating typically associated with 2-wire RTD configurations with long lead wire lengths.
      • The 3.85 Ohms per degree °C change for a Pt1000 has 10 times the output as compared to 0.385 for a Pt100 sensor. The greater nominal resistance of the Pt1000 sensor’s compensates for these added wire resistance errors.
    • The lower power usage of Pt1000 also results in less self-heating and fewer errors in the reading as a result of higher-than-ambient temperatures.
      • Battery-operated applications can also benefit from the higher nominal resistance of the Pt1000 due to a reduced use of electrical current and lower power requirements to operate. 

    • Pt1000 sensors are commonly used in refrigeration, heating, ventilation, automotive, and machine building applications. The Pt100 temperature sensors are utilized more fequently in process applications,
