• 3290
• Standard 3-wire Pt100 RTD probes

Compatibility & Fitment

• Compatible with PID temperature controllers, digital thermometers, PLCs, and data acquisition systems that accept a 3-wire Pt100 input.
• Probe diameters and lengths vary by model to fit different thermowells and mounting requirements.
• Available with process connections such as 1/2 in. NPT threads for secure installation in pipes or vessels.

When to Replace

• Inaccurate, fluctuating, or erratic temperature readings.
• Controller displays an open circuit, short circuit, or sensor error message.
• Visible physical damage to the probe sheath, transition, or cable insulation.
• No response to changes in temperature.

Installation Tips

• Ensure the measurement device is configured for a 3-wire Pt100 RTD input.
• For liquid or gas measurement, ensure the sensing portion of the probe is fully immersed in the flow.
• Do not bend the cable sharply at the probe transition point.
• Verify wire connections are correct per the controller's documentation (typically two common wires and one sense wire).
• Use a thermowell for applications in high-pressure or corrosive environments.
