The temperature and humidity transmitter launched by Shanghai Automation Instrument Co., Ltd. has become a core monitoring equipment in industrial automation, environmental monitoring, and people's livelihood fields due to its highly integrated design and intelligent functions. This product achieves comprehensive improvement in measurement accuracy, environmental adaptability, and operational convenience by integrating temperature and humidity sensors, signal processing modules, and display units, providing accurate and reliable temperature and humidity control solutions for multiple industries.

Core Function: Precise Perception and Intelligent Processing

high-precision measurement

A temperature and humidity transmitter using thermocouple, thermistor or capacitive humidity sensor, combined with linearization compensation algorithm, can achieve temperature measurement range-200℃to+1600℃Humidity measurement range0%RHto100%RHThe accuracy reaches±0.1℃(Temperature) and±2%RH(Humidity). For example, in sterile workshops in the pharmaceutical industry, equipment can monitor temperature and humidity fluctuations in real time to ensure that the drug production environment meets the requirementsGMPStandard to avoid drug degradation caused by excessive humidity.

Multi signal output and remote transmission

Device support4-20mACurrent signalRS485Digital signals and wireless transmission (such asLoRaTheNB-IoT）, can be combined withPLCTheDCSSeamless integration with control systems or cloud platforms. In cold chain logistics, real-time temperature and humidity data of the carriage is uploaded to the monitoring platform through wireless modules, allowing transportation companies to remotely track the status of goods, intervene in abnormal situations in a timely manner, and reduce loss rates.

Self diagnosis and adaptive functions

The built-in intelligent chip can automatically calibrate the zero drift of the sensor, and throughHARTProtocol implementation for remote parameter configuration. For example, in the monitoring of chemical reaction vessels, the equipment can dynamically adjust the measurement range according to the characteristics of the medium, and ensure stable operation in highly corrosive gas environments through reverse protection, current limiting protection, and other designs.
