Ethernet Multilogger - universal datalogger with 4 inputs

Battery powered datalogger with 4 universal inputs for measurement of 0-10V voltage, 0-20mA current, two-state signal and for counting pulses.
Signals are connected to four detachable terminal blocks.
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 Multilogger is a battery operated datalogger capable of measuring and recording sensor and electrical values through its Inputs.
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.

Features

Up to 4 physical Inputs - TERMINALS

Sensors with voltage output (range 0-10 V; accuracy ±10 mV)
Sensors with current output (range 0-20 mA; accuracy ±20 µA)
Sevices 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

Evaluation of up to 16 variables

Up to 16 variables may be calculated from the four connected probes / sensors. This is the sum of the measured and calculated values. The calculated values can be a further expression of moisture – dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. It can be also the result of inter-channel conversions, e.g. the difference of two connected temperature probes.

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

Power supply

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.

Communication interfaces

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

Multilogger - Alarm limits and alarm indication

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 - 12 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.
