Siemens Building Technology 533-376-18 Temperature Sensor
The Siemens 533-376-18 is a high-precision duct temperature sensor engineered for commercial building automation and industrial HVACR environments. This 18-inch rigid probe sensor utilizes a 100 Ohm Platinum RTD (Pt100) sensing element to deliver superior stability and measurement accuracy. Built for integration with modern BAS architectures, it features a 4-20mA output signal, making it compatible with a wide array of controllers from Siemens Building Technology and other major manufacturers using standard loop-powered transmitter inputs.
Designed for medium-to-large ductwork, the 533-376-18 temperature transmitter operates across a calibrated range of 20°F to 120°F (-7°C to 49°C). The 18-inch stainless steel probe provides a significant "reach" into the air stream to bypass laminar boundary layers, ensuring the HVAC temperature measurement reflects the true thermal state of the supply or return air. The unit is housed in a standard 2x4-inch electrical conduit box with lead wire connections, simplifying the field installation process for technicians replacing legacy Siemens 533 series components or installing new building automation sensors.
- High-Accuracy Sensing: The 100 Ohm Platinum RTD ensures minimal drift over time compared to thermistor-based alternatives.
- Industry Standard Output: The 4-20mA signal allows for long cable runs with high noise immunity in electrically noisy mechanical rooms.
- Durable Construction: Features a rigid 18-inch probe suitable for high-velocity duct applications where flexible probes may whip or vibrate.
- Seamless Integration: Specifically designed for Siemens HVAC controls, ensuring plug-and-play compatibility with existing loops and analog input cards.
Is the 533-376-18 compatible with non-Siemens controllers?
Yes, because it utilizes a standard 4-20mA transmitter signal, this sensor is compatible with any HVAC controller or PLC that accepts a 2-wire loop-powered 4 to 20 mA input.
What is the accuracy rating of this sensor?
The Siemens 533-376-18 provides a high level of precision, typically maintaining an accuracy of +/-0.54°F at the 32°F reference point.
Can the 18-inch probe be cut to a shorter length?
No, the probe is a sealed rigid unit containing the RTD element. Cutting or bending the probe will damage the internal sensing circuitry and void the technical performance ratings.
