Siemens Building Technology 536-778 Sensor
The Siemens Building Technology 536-778 is a high-precision outside air temperature sensor engineered for demanding building automation and HVAC control strategies. Utilizing a 100k Ohm NTC thermistor sensing element, this unit provides a highly stable resistance output that corresponds to ambient thermal changes, ensuring your building controller receives accurate data for outdoor reset and ventilation logic. Housed in a ruggedized metal enclosure, the 536-778 is built to withstand extreme environmental conditions, maintaining performance across a wide operating range of -40°F to 150°F (-40°C to 65°C).
Designed for professional installation, the sensor features lead-wire connections and a terminal-free interface for direct integration into 18 AWG twisted, shielded cable runs. This analog temperature sensor is widely compatible with North American building automation systems (BAS), offering a cost-effective solution for monitoring outside air conditions without the need for locally powered displays. Its accuracy of ±0.5°F at 77°F makes it a reliable choice for energy management systems and industrial process controls where precise outdoor air sensing is critical for system optimization.
Key Benefits- High-Resistance Precision: The 100k Ohm thermistor minimizes the impact of lead wire resistance, providing superior signal integrity over long cable runs.
- Rugged Metal Housing: Built to protect the precision sensing element from corrosion, humidity, and mechanical impact in all climates.
- BAS Compatibility: Native integration with Siemens building controllers and most HVAC automation platforms using standard 100k Ohm resistive input.
- Wide Operating Envelope: Reliable thermal monitoring from sub-zero arctic conditions up to 150°F, ideal for diverse geographic installations.
- Streamlined Installation: Compact design supports through-the-wall or surface mounting using standard hardware, reducing field labor time.
What is the resistance value of the Siemens 536-778 at 77°F?
This sensor utilizes a 100,000 Ohm reference resistance at 77°F (25°C). It is a negative temperature coefficient (NTC) thermistor, meaning resistance decreases as the temperature rises.
Can the 536-778 sensor be used for chilled water applications?
While primarily designed as an outdoor air sensor, its thermal response and metal construction make it suitable for measuring air temperatures near fluid lines; however, for immersion in fluids, a dedicated immersion sensor with a thermowell is recommended.
Does this sensor require a separate power supply?
No, the 536-778 is a passive resistive sensor. It functions by providing a change in resistance that the building controller interprets as temperature; no external voltage is required for the sensor itself.
