Siemens Building Technology 535-741-4 Sensor
The Siemens Building Technology 535-741-4 Sensor is a professional-grade duct temperature sensor designed for integration into commercial and industrial HVAC control systems. Utilizing a high-precision 100k Ohm thermistor (NTC Type II), this unit provides an accurate resistance-based output signal to track air temperature fluctuations within air handling units or supply/return ductwork. The 4-inch rigid probe is constructed from durable materials to withstand high-velocity airflow, ensuring long-term reliability for standard duct sizes.
This point-type HVAC duct sensor features a temperature measuring range of -40 to 180 degrees Fahrenheit (-40 to 82 degrees Celsius) with a typical accuracy of +/- 0.50°F at 77°F. The 535-741-4 is housed in a standard 2x4 inch galvanized steel junction box with 1/2-inch knockouts, facilitating a familiar installation process for field technicians. With its lead-style connection and lack of a local display, it is optimized for high-density building automation system deployments where remote monitoring is the priority.
Key Benefits:- 100k Ohm Thermistor: Delivers precise temperature signals for Siemens and other compatible BAS controllers.
- Rigid 4-Inch Probe: Engineered for point-sensing applications in standard duct profiles.
- Wide Operating Range: Reliable performance from extreme cold (-40°F) up to high-heat conditions (180°F).
- Steel Enclosure: Includes an NEC-approved utility box for secure termination and environmental protection.
- Standard Installation: Leads-based connection type integrates seamlessly with 18-22 AWG twisted pair wiring.
- How do I wire the Siemens 535-741-4? The sensor uses a 2-wire lead connection. It is recommended to use twisted, shielded cable pairs to minimize electrical noise in long-distance runs to the controller.
- Can this sensor be used for averaging? No, the 535-741-4 is a point sensor. For large ducts with temperature stratification, an averaging sensor version should be selected.
- Is a mounting flange required? While the attached junction box provides a primary mounting surface, a gasketed mounting flange can be used to ensure an airtight seal at the duct penetration.
