Data logger for current 0-20mA, voltage 0-5V and binary signal

Data logger for current 0-20mA, voltage 0-5V and binary signal Data loggers are designed for record of voltage signal 0-5V (optionally 0-10V) or current signal 0-20mA. At the same time state of binary signal can be recorded. Values are stored to a non volatile electronic memory. Data transfer to the personal computer for further analysis is performed via USB, RS232, GSM or Ethernet interface by means of a proper adapter. Main applications of data logger: * Distant places with no electric power * Long term field measurement * Research and development * Laboratories * Technological processes Advantages of data logger: * included traceable calibration certificate from the manufacturer - Comet * fast data transfer to the PC (full memory for approximately 30s) * variability of connection to the computer - USB, RS232, Ethernet, GSM modem * permanent connection to the PC enabled, data is possible to download even during logging * large data memory 32000 values * large dual line display with special symbols, switchable * optional display of minimum and maximum measured values (reset of min/max memory from PC or by magnet) * dual level alarm is enabled for each channel, alarm is indicated by blinking of the value on the LCD display * two alarm modes are enabled: instant or with memory (detected alarm is indicated permanently till alarm memory is cleared) * robust watertight case * easy installation, locking enabled * low power consumption from battery, battery life up to 6 years * indication of remaining battery life, easy replacement of the battery * logging start/stop is enabled: at certain time and date programmed from computer, by external binary signal or by delivered magnet * also special logging mode is enabled, when logging runs only, if some of measured values are out of adjusted alarm limits * input signal is recalculated and displayed in real measured physical units by means of the PC software * each logger is possible to describe with text of maximum 32 characters * each channel is possible to describe with text of maximum 16 characters * password protection is enabled to prevent unauthorized manipulation with logger TECHNICAL PARAMETERS Measurement accuracy: ±0.2% FS Resolution of voltage input: 13 bits (8192 levels) Resolution of current input: 7900 levels Signal character at binary input: from potential-less contact or two-state voltage signal Minimum pulse duration at binary input: 500 ms (shorter pulses may not be recorded) Maximum frequency at binary input: 0.5 Hz (i.e. maximum 5 pulses for 10 s) Power current through contact at binary input: 3 uA (contact closed) Voltage accross open contact at binary input: maximum 3.6 V Low voltage level at binary input: 0 to +0.2 V (maximum current from the input 3 uA High voltage level at binary input: +3.0 to +30 V (maximum current to the input 100 nA Data logging interval: adjustable from 10s to 24hours Display refresh and alarm state refresh: every 10 s Total memory capacity: 32000 values (in non cyclic mode) Data logging modes: noncyclic – logging stops after filling the memory cyclic – after filling memory oldest data is overwritten by new Operation temperature range: -30 to +70°C Real time clock: year, leap year, month, day, hour, minute, second Built-in connector for input signals: Canon 9 pins, male Dimensions without connectors: 93x64x29mm Weight including battery: 130g Power: Lithium battery 3,6V, size AA Typical battery life in operation from -5 to +35°C: (if often operated outside of the above temperature range battery life can be reduced to 75%) 6 years Battery life in continuous on-line mode with interval 1 minute: 4 years Battery life in continuous on-line mode with interval 10 seconds: 1 year Protection: IP67 - protected against influence of temporary immersion into water Warranty: 2 years
