GSM/GPRS data logger/ Telemetry System/monitoring

      Relative humidity: 95%

      Storing temp.: -40~+85?C

      Environment temp.: -25~+70?C

      Measurment: 147*147*228.7mm (Excluding antenna and installing parts)

      Protection classIP68,dIIBT4.

      RS232/485default 38400-8-N-1. For direct data logging, it may need to change software depending on instruments.

      Analog inner resistor250ohm,standard 4~20mA(1~5VDC)input,and 0~20mA(0~5VDC) is ok,too.

      Active pulse(valid voltage>5V,invalid voltage<0.5V.

      Passive pulse(valid resistor value<10K,invalid resistor value>1M)

      Transmission: GSM SMS/GPRS.

      Power: battery(DC7.2V),external power (DC8V~26V).

      Support GSM900MHZand EGSM1800 double frequency MH as standard of GSM Phase2/2+.

Technical specification:

      A rugged water-proof enclosure, IP68 protection class.

      A sent message counter for users to know the remaining sum

      A real time monitoring for battery voltage..

      A friendly interaction with mobile phone,and password validated. All data parameters can be set by GSM.

      Data LCD display,the keypad only for inquiry..

      The function of data compensation which means: if you are fail to send the last data, it will compensate it after successfully sending it next time in the valid time.

      For saving cost, one message can contain multi-time data. For example, when want to receive one way flow totalizer, one message sent per day, but the message can contain totalizer of every half an hour.

      Function of intelligent error-correction

      Real time data inquiry (no saving energy mode) and reservation inquiry which is energy saving mode: each other 3 days(147) will open 6 minutes to automatically receive and handle sent messages. The open time can be set.

      While uploading data, uses can set four reception telephone numbers and 2 IP (GPRS) to meet different request. The uploading time can be set in 15s to 1day.

      Timing data saved. The interval can be set between 1hour and 2hours. Can store 14336 data,users can see about valid history data by fuzzy inquiry.

      Alarm functionalarm for switch status (e.g. for power ON/OFF),for upper/lower limit, for abnormal flow rate, those alarm messages will be informed by GSM and telephone. Four alarm telephone numbers can be set.

f. A infrared 38KHz(1200Bit) Port or 33MHz RFIs, for setup and inquiry.

e. A isolated RS232/485port can be used for setting and reading, e.g. flowmeter must be directly data logged.(The flowmeter must have standard RS232/485 Port and communication protocol).

d. A 24VDC(I<45mA) output,can provide power source for pressure transmitter and other small type instruments. The function is available while battery powered.

c. 2 relays (220VAC1A) dry contact output. ON/OFF the relay by GSM telemetry setup, and also set a certain alarm to operate relay.

b. 6 channels pulse/switch input which can be set by software.

a. 6 channels 12gigits analog data logger,resistor 250ohm,standard 4~20mA(1~5VDC) input,also do any input in the range of 20mA. Can set measurement range and zero point.
