What are Wireless Sensors in Catalysis?
Wireless sensors are devices that monitor and transmit data regarding various parameters without the need for physical connections. In the context of
catalysis, these sensors can measure temperature, pressure, concentration of reactants and products, and other critical variables that influence catalytic reactions. The data collected by these sensors can be used to optimize and control catalytic processes in real-time.
-
Real-time monitoring: Enables the immediate detection of changes in process conditions.
-
Flexibility: Easier to install and reposition as they do not require wiring.
-
Cost-effective: Reduces the installation and maintenance costs associated with wired systems.
-
Safety: Minimizes the risk of electrical hazards in explosive or hazardous environments.
How Do Wireless Sensors Work?
Wireless sensors typically consist of a sensing element, a microcontroller, and a wireless communication module. The sensing element detects the parameter of interest (e.g., temperature or pressure) and converts it into an electrical signal. The microcontroller processes this signal and transmits it wirelessly to a central data collection system, often using technologies like
Bluetooth,
Wi-Fi, or
Zigbee.
