Features
Features
Up to 4 physical MiniDin Inputs
- 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.
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 email when an alarm state begins or ends
- Use DATALINK: display current values or download values from memory to the COMET database on your PC. COMET Database software contains many useful tools for data analysis: graphs, tables, statistics, etc.
- Easy wireless communication with TP-LINK Wi-Fi router
- Third-party applications to read actual measured values using universal SNMPv1 and XML protocols
- View current measured values using your web browser.
Output ALARM OUT
- The output can be used to control other devices when the alarm is triggered, such as an external buzzer, telephone dialer, etc.
- Output type: Open collector transistor
- Maximum switching current: 100 mA
- Maximum voltage at output: 12 V
- Auxiliary voltage at terminal: +5 V (only when mains supply is present)
- Users can receive alarms if values go outside the set parameters. Alarms are indicated via an internal buzzer, 3 LEDs or email alerts via the Ethernet port.
