Hebei OSU Electronics OSA-9Y Leaf Temperature Sensor Thermistor

OSA-9YLeaf surface temperature sensor consists of high-precisionNTCIt consists of thermistor and transmitter. With offset compensation and temperature calibration functions,the temperature can be accurately measured within the entire range. The shape of the sensor adopts a blade-like design to truly simulate the characteristics of the leaf surface,so it can more accurately reflect the leaf surface environment.

Low power consumption enables long-term uninterrupted monitoring. It is easy to install and can be hung on the greenhouse or mounted on the mast of the weather station.

（1) imitates leaf surface characteristics and measures quickly and accurately.

（2) Low power consumption design,adopting reasonable power consumption control mode.

（3) selectable analog voltage/current,RS485signal output.

（4) has a high-precision temperature correction function and can independently output the temperature signal.

（5)useABSIt is encapsulated with epoxy resin and uses gold plating process on the sensing surface to ensure a life.

It is widely used in meteorology,environment,agriculture,forestry,water conservancy,electric power,scientific research and other fields that require temperature measurement.
