Frost Sensor is a unit that combines two precise thermistors, or temperature sensors, into one housing. Both sensors are created to look like plant leaves and flower buds, respectively. The SF-110 can be used to predict frost on leaves and buds since it delivers accurate estimates of leaf and bud temperatures.
The device, a frost sensor, monitors the reduction in heat flow brought on by increased thermal resistance of ice (reduced conduction), as well as the reduction in heat flow brought on by airflow obstruction brought on by excessive ice development (reduced convection).
Instead of on a predetermined schedule, the sensor initiates a defrost cycle as necessary. The invention also includes a technique for preventing frost in a system that uses a thermal channel to transmit heat from air to a refrigerant.
The process entails measuring the thermal conductivity of the thermal channel from the air to the refrigerant and identifying a decrease in thermal conductivity brought on by the thermal insulation effect of frost and the reduction in airflow caused by excessive ice development;
Global frost sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Frost Sensor SF-110 Features
The SF-110 combines two precision thermistors (temperature sensors) into a single enclosure. Both sensors are created to look like plant leaves and flower buds, respectively. The SF-110 can be used to predict frost on leaves and buds since it delivers accurate estimates of leaf and bud temperatures.
Even if the air temperature is just slightly over freezing on clear, quiet nights, the temperature of the leaves and buds can go below freezing.
A lack of air mixing (wind) near the surface and a negative net longwave radiation balance at the surface are what cause this phenomenon, known as a radiation frost (more longwave radiation is being emitted from the surface than what the surface is absorbing from the clear sky).
The SF-110 has a temperature measuring range of -40 to +70°C with a precision of 0.1°C from 0 to +70°C. The sensor is intended for use in crop fields and orchards, where frost formation cannot be accurately predicted by air temperature measurements when temperatures are expected to be close to freezing.
