Jauntering - Model HL20 -Data Acquisition Datalogger System
The HL20 datalogger is a powerful data acquisition system suitable for various applications including meteorology, hydrology, ambient air pollution, agriculture, industry, wind and solar power energy, water quality & resource , ground water, soil erosion research, debris flow, geotechnical measurement, etc. It can work as a stand-alone station or be operated and controlled by remote IBM compatible PC or through dedicated line, dial-up modem or GSM modem or Internet as a monitoring systems network.
The HL20 measurement and control system consists of an ISO 9001 approved environmental enclosure, a HL20 datalogger, a P12RB AC/DC power with built-in 7AH rechargeable battery, RS232 converter interface, datalogger support software, etc. The HL20 datalogger can provide excitation voltage outputs for sensors while scanning, which absolutely save power consumption and keep system running more longer at sites where have no AC power sources. The data either be stored in internal storage can be directly retrieved by PC through a PC cable, or removable solid state storage module which can be brought back to office to retrieve data by desktop PC.
User programming of HL20 is easily accomplished through an IBM compatible PC with datalogger support software (On-line help). The wiring diagram and comprehensive on board instruction table as program example are included, which can be programmed to perform calculations on any desired channel. Also, the offered program example can be modified easily through datalogger support software.
