Comet U0843M 用于2个外部探头的物联网无线温度数据记录器,具有两个两态输入,内置2G调制解调器 (Li-Ion A8200, 3.6V/5200mAh)

Measured value: Temperature, Two-state signal

Temperature sensor - external probe PT1000:

  Measuring range: -200 to +260 °C

  Accuracy: ±0.2°C; ±0,2 % of the measurement value in a range of +100 to +260 °C

  Resolution: 0.1 °C

  Response time t90 of temperature measurement (temperature step 20°C, air flow approximately 1m/s): according to the connected probe

Binary input:

  Parameters of the voltage contact: "L" level input voltage: < 0,4 V(*);

                                                         "H" level input voltage: > 2 V;

                                                          Minimum voltage applicable: 0 V;

                                                          Maximum voltage applicable: +30 V DC

  Parameters of the voltage-free contact: Contact resistance in "switched-on" state: < 10 kOhm;

                                                                 Contact resistance in the "switched-off" state: > 300 kOhm;

                                                                 Contact voltage in the "switched-off" state: ca 3 V;

                                                                   Minimum state duration necessary for latching the state: 1s

GSM modem parameters:

  Quad-band: 850/900/1800/1900MHz

  Compliant to GSM: Phase2/2+

  GPRS: GPRS mobile station class B

  Class 4: 2W @ 850/900MHz

  Class 1: 1W @ 1800/1900MHz

Operating temperature: -20 to +60 °C

Channels: 2x external temperature probe, 2x binary input

Memory: 500 000 values in noncyclic logging mode; 350 000 values in cyclic record mode

Recording interval to the internal memory: adjustable from 1 second to 24 hours

Recording interval to the COMET Cloud: from 5 minutes

Interval for measuring and evaluating alarms: adjustable 1 s, 10 s, 1 min

Recording mode: noncyclic - data logging stops after filling the memory

                            cyclic - after filling memory oldest data is overwritten by new

Real time clock: year, leap year, month, day, hour, minute, second

Power: rechargeable Li-Ion battery A8200, 3.6V/5200mAh

Protection class: IP20
