Relative Humidity & Ambient Temperature & Pressure Sensor (3S-RH&AT&PS)-1

Relative Humidity, Ambient Temperature and Pressure Sensor The Relative Humidity, Ambient Temperature and Pressure Sensor is part of the SEVEN meteorological sensor range, which includes professional and intelligent measuring sensors with a digital or analog interface for environmental and industrial applications such as PV plants. The relative humidity, temperature and pressure sensor is protected by UV resistant shield which is delivered with the product. It is a measuring transmitter used for the measurement of the relative humidity, ambient temperature and pressure. The measured relative humidity, data is transmitted as analog output while it is tramsmitted along with the ambient temperature and pressure as digital output signal to the data loggers and receiver units according to the input requirements. SEVEN products use reliable and high-quality components to provide accurate meteorological information in environmental and industrial applications. They are specially designed according to the requirements of PV plant monitoring systems.
