PDSH12-5,08

PDSH12-5,08 is a kind of electric digital display temperature and humidity transmitters. It is designed based on today’s modern digital technique, and is applicable to meet the demand of various kinds of series installation site environment.

This device has two parts, a main unit and a probe. The main unit is mounted in the cabinet, and the probe is mounted on the site. It monitors the temperature and humidity and transmits the measured information to the main unit for display and recording. Through a series of processing, such as filtering, linear characteristics conversion, conversion algorithm, etc., the measured values will be converted into digital display and voltage signal after processing with correction and compensation.

The PDSH12-5,08 applies a chip module of field extended type as the core, which combines sensor, analog conversion, display, and correction and compensation. This ensures the device to be more accurate and reliable in performance. This device can be installed in the temperature and humidity monitoring system, to meet the demand of site measurement and control.

The main applications of PDSH12-5,08 include meteorology, agriculture, industry, etc. In meteorology, it is used for weather station, air climate monitor, and automatic weather station in observing temperature and humidity. In agriculture, it is used for farm environment observation, soil temperature and humidity observation and archival. As for industry, it is used for environmental monitoring, although it can also be used in material temperature and humidity monitoring, air exchange monitoring, and automatic control.

The working principle of PDSH12-5,08 can be summarized as below. Firstly, when the temperature and humidity are detected by probe, they are then converted into analog voltage signal and transmitted to total station. QHoo cupple then processes the analog voltage signal, corrects and compensates the linear conversion formal characteristic, calculates the converted data and digital displays the measured values on LED’s display unit. At last, the total station converts the analog voltage signal into digital signal and transmits them to the main unit for display.

The working process of PDSH12-5,08 can be divided into three parts: detecting, digitizing and transmitting. When the temperature and humidity are detected by probe, the digital transmitting module in total station converts it into digital signal. After that, the signal is transmitted to the main unit which is in digital frequency output mode. The receiver then displays and transmits the digitized signals by digital technique.

To sum up, the PDSH12-5,08 is a kind of widely used electric digital display temperature and humidity transmitter, which combines sensor, analog conversion, display, and correction and compensation. It is widely used in various fields such as meteorology, agriculture, industrial environment monitoring. Its working principle can be summarized as detecting, digitizing and transmitting.
