A Firmcompute 130 mAh Ultra Small Wireless Temperature Sensor Transmitter, FC-153 BT is a device used to measure temperature and convert the measured temperature into an electrical signal that can be transmitted to a monitoring or control system. These transmitters are commonly used in industrial processes, HVAC systems, laboratory equipment, and other applications where accurate temperature monitoring and control are essential. Here are the key features and components of a typical temperature transmitter: Temperature Sensor: The temperature transmitter is equipped with a temperature sensor that detects changes in temperature and converts them into electrical signals. Common types of temperature sensors used in temperature transmitters include thermocouples, resistance temperature detectors (RTDs), and thermistors. Signal Conditioning Circuitry: The electrical signal generated by the temperature sensor is often weak and may need to be amplified or conditioned before transmission. Signal conditioning circuitry within the temperature transmitter processes the raw sensor signal to ensure accuracy, stability, and compatibility with the receiving equipment. Output Signal: The output signal of the temperature transmitter is typically a standardized analog or digital signal that can be easily interpreted by the receiving equipment. Common output signals include 4-20 mA (milliampere) analog signals, 0-10 V (volt) analog signals, or digital signals such as Modbus, HART, or Foundation Fieldbus. Housing: Temperature transmitters are housed in protective enclosures or casings that shield the internal components from environmental factors such as moisture, dust, and vibration. The housing may be made of materials such as stainless steel, aluminum, or plastic, depending on the application requirements. Mounting Options: Temperature transmitters may have various mounting options to accommodate different installation requirements. They can be mounted on DIN rails, directly onto equipment or machinery, or integrated into control panels or cabinets. Calibration: Temperature transmitters are typically factory-calibrated to ensure accurate temperature measurement. Some models may also offer user-adjustable calibration settings to fine-tune the measurement accuracy as needed. Communication Protocols: Advanced temperature transmitters may support communication protocols that allow them to interface with programmable logic controllers (PLCs), distributed control systems (DCS), supervisory control and data acquisition (SCADA) systems, or other monitoring and control devices. Temperature transmitters play a crucial role in industrial automation and process control, providing accurate and reliable temperature measurement data for monitoring, analysis, and control purposes. By transmitting temperature information in real-time, these transmitters help optimize process efficiency, ensure product quality, and enhance safety in a wide range of industrial and commercial applications.
