Ethernet Multilogger - thermo-hygro-CO2 meter with 2 MiniDIN and 2 Terminals
Battery powered datalogger with built-in CO2 sensor and 4 universal inputs for measurement of temperature, humidity, 0-10V voltage, 0-20mA current, two-state signal and for counting pulses.
Multilogger can be installed permanently to Ethernet network or work as portable device.
Included is traceable calibration certificate in accordance with EN ISO/IEC17025.
The device is designed for measuring and recording temperature, humidity, CO2 (internal sensor) with adjustable recording intervals from 1 second to 24 hours.
Datalogger can be connected to Ethernet. Then measured values can be viewed on a web browser, as well as stored and downloaded for later analysis.
- on-line monitoring
- recording of data
- alarm warnings
TEMPERATURE SENSOR - external probe Pt1000
±0.2 % from reading from +100 to +600 °C
TEMPERATURE+HUMIDITY SENSOR - external probe T+RH DIGI
GENERAL TECHNICAL DATA
2x binary, counter, voltage and current input
cyclic - after filling memory oldest data is overwritten by new
Up to 4 physical Inputs - 2x TERMINALS + 2x MiniDin
Removable inputs allows connection of:
- Sensors with woltage output (range 0-10 V; accuracy ±10 mV)
- Sensors with current output (range 0-20 mA; accuracy ±20 µA)
- Devices with two-state output (potential-less contact or voltage signal 0-30V); may be applied to input 3 and 4
- Devices with pulse signal (potential-less contact or voltage signal 0-30V); may be applied to input 4
- Temperature probes Pt1000 with built-in configuration memory (serie xxx/M)
- Temperature/relative humidity probes with digital output - DigiS/M, DigiL/M, DIGIH/M
- The probes are interchangeable without calibration to a specific device and regardless of the length of the cable. The length of the cable can be 1, 2, 5, 10, 15 meters
- Internal CO2 sensor with range 0-2000 ppm (custom range 0-10.000ppm)
Evaluation of up to 16 variables
The measured values are stored in the internal non-volatile memory. Memory capacity is up to 1 million values. Logging mode can be adjusted as non-cyclic, when logging stops after filling the memory, or cyclic, when after fulfilling the memory oldest stored values are overwritten by new ones.
Measured values are displayed on the screen with backlight option and the ability to change the size of display digits
Multilogger can be powered by AC adapter or by rechargeable batteries with charging capability. Batteries are always a part of the device (you can also use standard alkaline AA batteries). Batteries power the device for several months.
While using the AC adapter, the batteries provide backup operations and provide recording and measurement during power failure. Thanks to the Ethernet output the device informs about the failure via e-mail message.
Alarm limits and alarm indication
It is possible to set two independent alarm limits for each channel (i.e. measured or calculated value).
Alarm signalization can be acoustic (built-in beeper), optical, sending an e-mail alert or an alarm output. The alarm output is for connecting an external audio or visual alarm.
Multilogger is always equipped with USB connector for communication, data analysis and also for charging of the rechargeable batteries.
- send an e-mail when an alarm state starts or ends
- use DATALINK: display current values or download values from memory to COMET Database in your PC. Software COMET Database contains many useful tools for data analysis - graphs, tables, statistics, etc.
- simple wireless communication with Wi-Fi TP-LINK router
- third-party applications to read the actual measured values using universal protocols SNMPv1 and XML
- view current measured values using your web browser
Output ALARM OUT
- Output can be used for controling other devices when alarm is launched, such as external buzzer, telephone dialer etc.
- Type of output - open collector transistor
- Max. switching current - 100 mA
- Max. voltage on output - 24 V
- Auxiliary voltage at terminal - +5 V (only when the mains supply is present)
- Users can receive alarms if the values go outside the paramters set. Alarms are indicated through an internal buzzer , 3 LEDs or email alerts via Ethernet port.
