Siemens Building Technology 536-811 Sensor
The Siemens 536-811 is a high-precision duct temperature sensor engineered for critical monitoring in forced-air HVAC systems. Featuring a 100k Ohm thermistor (Type II NTC), this sensor provides an accurate and responsive output signal, ensuring seamless integration with equipment controllers such as the Modular Building Controller (MBC) and Terminal Equipment Controllers. The 4-inch rigid probe is constructed for durability, maintaining a stable position within the airstream for consistent point temperature sensing across a wide operating range of -40 to 180 degrees Fahrenheit.
Designed for the field technician, the Siemens Building Technology 536-811 utilizes a bracket-mounted design. The thin steel mounting plate is easily formed to fit round or square ductwork, while the 18 AWG lead connections facilitate rapid wiring without complex terminals. This HVAC thermistor sensor is essential for contractors requiring a reliable, no-display solution for air temperature monitoring and automation control.
Key Benefits- High-Resistance Precision: The 100k Ohm thermistor element ensures accurate data transmission to high-impedance controllers.
- Versatile Duct Mounting: A flexible steel bracket allows for quick installation on irregular or standard round duct contours.
- Rugged 4-Inch Probe: The rigid probe length is optimized for single-point air measurement in standard commercial duct sizes.
- Wide Temperature Range: Operates effectively from -40 to 180 degrees Fahrenheit, covering extreme heating and cooling cycles.
- Labor-Saving Connection: Includes leads and self-stripping connectors for fast integration with twisted, shielded cable pairs.
Is the Siemens 536-811 compatible with non-Siemens controllers?
This sensor is a 100,000 Ohm NTC thermistor. While designed for Siemens Building Technology systems like the RBC and SCU, it is compatible with any controller that accepts a standard 100k Ohm Type II thermistor input signal.
Does this sensor require a junction box for installation?
No, the 536-811 is a bracket-mounted "no box" design. It mounts directly to the duct exterior using a gasket and the provided self-tapping screws for a low-profile installation.
Can the probe be adjusted or bent?
The 4-inch probe is rigid to ensure it remains centered in the airflow. The mounting plate itself is flexible for duct surface alignment, but the sensing element housing should not be bent.
