PR204 Series intelligent temperature and humidity acquisitor uses intelligent connector to connect various thermocouples, thermal resistors and humidity transmitters. The intelligent connector integrates reference end sensor and memory, and can be used as a whole after being combined with the sensor, so as to realize the functions of intelligent identification, classification and editing of sensors, which greatly improves the intelligence level of the acquisitor.
In addition, the acquisitor uses an embedded operating system, which can realize inspection configuration, data viewing, sensor correction, data statistics, curve display and other operations without other peripherals. After using the cloud metrology function, the temperature control deviation, temperature field, humidity field, uniformity, volatility and other parameters of heat treatment furnaces and temperature (humidity) environment experimental equipment can be automatically tested and analyzed online.
Self-locking intelligent connector, using PR2046 intelligent connector to connect with thermocouple, thermal resistor, humidity sensor to form intelligent sensor. The intelligent connector has a self-locking jack, which can quickly and reliably connect the sensor test line. The internal integrated temperature sensor and memory can be used for the measurement of the thermocouple reference end and the storage of sensor number, correction value and other data.
Intelligent sensor identification: After the intelligent sensor is inserted into any channel of the acquisitor, the acquisitor automatically loads the sensor data and automatically classifies and sorts the channels by type and connection order without the need for additional configuration.
It has 24 multi-function channels, any channel supports the measurement of 11 types of thermocouples, four-wire Pt100 and humidity or other types of transmitters with 0-1V output. The measurement channels can be divided into up to four groups for operation, management and storage, which is convenient for the measure of multiple devices being calibrated simultaneously.
The channel switching uses a mechanical relay array, which does not cause additional electrical measurement errors due to leakage current, thereby achieving excellent channel consistency. Another advantage of the relay structure is that the signal loop can withstand 250V AC voltage accidentally entering and can effectively suppress surge voltage impacts under harsh working conditions.
High data reliability, built-in industrial-grade FLASH memory is used to save the original data of each inspection operation. The data can be viewed and copied, but cannot be changed. During the inspection operation, the data can also be saved in an external USB flash drive at the same time, improving the security and reliability of the data through double backup.
The closed structure design adopts aluminum alloy shell, and the safety protection level reaches IP64, which can be used for a long time in harsh environments such as dust and vibration.
It uses a detachable intelligent lithium battery pack, which can run continuously for more than 12 hours when fully charged. The built-in battery management system can accurately estimate the remaining usage time based on the real-time power consumption, and can provide diagnostic information including battery cycle number, charge and discharge status, etc.
The Internet of Things function has built-in Bluetooth and Wifi modules, and can be used in conjunction with the PANRAN Smart Metrology Mobile APP to realize remote real-time monitoring, recording, data output, alarm and other functions of the networked devices; historical data is stored in the cloud for easy query and data processing; the software has rich permission configuration modules, and the user unit can independently manage the account of the unit, support the opening of multiple users online at the same time and the configuration of different user permission levels.
