Siemens Building Technology 544-343-18 Temperature Sensor

Siemens Building Technology 544-343-18 Temperature Sensor

Ensure reliable thermal monitoring in large-scale air handling units with the Siemens 544-343-18 Duct Averaging Temperature Sensor. Engineered for building automation systems (BAS), this high-precision 1k Ohm Platinum RTD sensor utilizes a 375-alpha resistance temperature detector to provide accurate feedback across a versatile range of -40°F to 180°F. The 18-inch rigid probe is purpose-built to combat temperature stratification within ductwork, delivering an averaging signal that represents true air mass temperature better than single-point alternatives. Designed for professional HVAC controls integration, this Pt RTD duct sensor features terminal lead connections and a 2x4-inch electrical box mount for streamlined installation in commercial air streams. Whether you are performing a Siemens HVAC sensor replacement or upgrading a building technology network, the 544-343-18 ensures high-impedance stability and long-term signal integrity without the need for frequent recalibration.

Key Benefits

  • Enhanced Accuracy: Features a 1000 Ohm Platinum RTD element that provides precise linear resistance changes for superior controller feedback.
  • Stratification Compensation: The 18-inch rigid probe length enables averaging temperature sensing, essential for accurate readings in large volume ducts.
  • Rugged Construction: Built for industrial environments with an operating range of -40° to 182° Celsius, ensuring durability in both supply and return air applications.
  • Seamless Compatibility: Standard 375a output signal integrates directly with Siemens Landis & Staefa and most North American building automation controllers.

Common Questions

How do I install the Siemens 544-343-18 in a pressurized duct?

For optimal results, mount the unit using a standard duct flange and gasket. Ensure the 18-inch rigid probe is positioned perpendicular to the airflow to capture a representative cross-section of the air stream. The 20 AWG twisted pair leads should be connected to the controller using shielded cable to prevent electromagnetic interference.

Can this replace a single-point 1k Ohm sensor?

Yes, provided the controller is calibrated for a 1k Ohm Pt RTD (375 alpha) curve. This averaging sensor is often preferred in larger ductwork where temperature variations across the duct diameter might cause a single-point sensor to provide misleading data.

Does this sensor require an external power supply?

No, this is a passive resistive device. It operates via the excitation voltage provided by your HVAC control system or PLC input module.
