OUTDOOR TEMPERATURE SENSORS FOR SALE

An outdoor air temperature sensor is an essential component of any modern HVAC or building automation system. These devices provide crucial real-time temperature data from outside your building, enabling your system to make smart decisions about heating, cooling, and ventilation operations.

These specialized sensors are designed to withstand various weather conditions while maintaining accurate temperature readings. Unlike indoor sensors, they feature robust weather protection and are specifically calibrated to handle wide temperature swings, direct sunlight, rain, snow, and other outdoor elements.

KEY COMPONENTS OF OUTDOOR TEMPERATURE SENSORS

Each outdoor temperature sensor includes several critical components that work together to ensure reliable operation and accurate readings in challenging outdoor conditions:

• Sensing Element: The core component that actually measures temperature, available as either a thermistor or RTD. This element changes its electrical properties based on temperature changes
• Protected Housing: A weather-resistant enclosure (NEMA 3R, 4X, or European style) that shields the internal components from rain, snow, UV radiation, and other environmental factors
• Radiation Shield: Special ventilated design that prevents direct sunlight from affecting temperature readings while allowing proper airflow around the sensing element
• Mounting Hardware: Sturdy brackets and fittings designed for secure outdoor installation, typically on exterior walls or soffits
• Signal Processing Components: In transmitter models, these electronic components convert the temperature reading into a standardized output signal that building automation systems can understand
• Connection Terminals: Weather-tight electrical connections that maintain signal integrity in wet conditions.

TYPES OF OUTDOOR TEMPERATURE SENSORS YOU CAN FIND AT BLACKHAWK SUPPLY

When selecting an outdoor temperature sensor for your HVAC system, heat pump, or boiler installation, it's crucial to choose the right type for your specific application. Our comprehensive range includes sensors for all common building automation needs, from basic outside air temperature monitoring to advanced environmental control systems.

SENSOR TYPES BY MAIN FUNCTION

Understanding the fundamental differences between sensor types will help you select the right device for your application. Our outdoor temperature sensors are divided into two main categories based on how they process and communicate temperature readings:

• Basic Temperature Sensors: These are pure temperature sensing devices that provide direct temperature measurement without additional signal processing. They use resistive elements (like thermistors or RTDs) that change their electrical resistance based on temperature. Perfect for systems that can directly read resistance values, these sensors offer:
  • Straightforward temperature measurement.
  • No need for additional power supply.
  • Direct integration with compatible controllers.
  • Excellent reliability due to simple design.
  • Cost-effective solution for basic temperature monitoring.
• Temperature Transmitters: These more sophisticated devices combine a temperature sensor with built-in signal processing electronics. They convert the raw temperature reading into a standardized output signal that building automation systems can easily interpret. Ideal for modern building control systems, temperature transmitters provide:
  • Standardized output signals for easy system integration.
  • Built-in temperature compensation.
  • Higher noise immunity over long wire runs.
  • Superior accuracy through signal conditioning.
  • Compatibility with a wider range of control systems.

The choice between these two types typically depends on your existing control system's capabilities, wiring requirements, and the level of signal processing needed for your application.

SENSORS BY ELEMENT TYPES SAND OUTPUT SIGNALS

When selecting an outdoor temperature sensor, understanding the element type and output signal is crucial as it determines compatibility with your control system. Our sensors offer various sensing technologies and output options to match your specific requirements.

Resistance Temperature Devices (RTDs)

RTDs work by measuring temperature through electrical resistance (measured in ohms). The resistance changes predictably as temperature changes. We offer sensors various resistance options:

• PT100 and PT1000 for highest precision needs
• 100 ohm (2-wire) for basic applications
• 1000 ohm options in 2-wire and 3-wire configurations

Thermistor Options

Thermistors also use resistance, but show larger resistance changes with temperature. We offer a wide range of thermistor resistance options to match your existing system:

• 10K Type II and Type III for standard applications
• 100K, 20K, and 3K for specific system requirements
• Specialized 10K variants including CSI and 10K with 11K shunt
• 1.8K for unique applications

Output Signal Types

For sensors that convert resistance to standardized signals:

• 4-20 mA current output for excellent noise immunity
• 0-10 VDC voltage output for standard control systems
• 0-5 VDC for specialized applications

SENSOR TYPES BY SENSING ELEMENT

Choose based on accuracy needs and system compatibility:

• Thermistor-based sensors
• RTD-based sensors
• Transmitter-based sensors

SENSOR TYPES BY HOUSING PROTECTION

Select based on your environmental conditions:

• NEMA 3R Bell Box Housing
• NEMA 4X Protection
• Weather Tight European Style
