Battery operated 16 input-channel datalogger with Ethernet interface
Multilogger
- use DATALINK: display current values or download values from
device memory to your PC - view current measured values using your web browser
- third-party applications to read the actual measured values using
universal protocols SNMPv1 and XML - send data to COMET DATABASE software which contains many useful tools for data analysis - graphs, tables, statistics, etc.
Main features
- up to 6 hardware inputs for measuring and recording, 16 virtual channels
- - temperature
- - humidity
- - dew point
- - atmospheric pressure
- - current 0 - 20 mA and voltage 0 - 10 V (-60 to 140 mV)
- - two-state events
- - pulses
- - CO2
- memory for 1 million values
- indication of alarm conditions via
- - SMS
- - integrated acoustic siren LEDs
- - stwo-state output to control other devices
- analytical software for data processing and configuration - Comet Vision
- communication interfaces - USB, RS232 and Ethernet (SNMPv1 and XML)
4 inputs
All models have 4 input connectors for external probes or signals. These may be supplemented by an internal atmospheric pressure transducer and / or CO 2 sensor.
Temperature probes Pt1000 (serie xxx/M)
Temperature/relative humidity probes with digital output (serie DIGI)
Sensors with bipolar output voltage and a range of- 60 to + 140 mV (heat flux sensors, etc.)
Devices with two-state output (monitoring of machine run, door open/ close, etc.)
Device with pulse output (gas and water meters, counter pieces on a production line, etc.)
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)
- the result of inter-channel conversions
(eg. the difference of two connected temperature probes)
Alarm limits
It is possible to set two independent alarm limits for each channel (ie. measured or calculated value) which can be configured either as an upper and lower limit or two limits exceeding in a consistent direction. Alarm signalization can be acoustic (built-in beeper), optical (3 LEDs), alarm output or sending an e-mail alert.
Power supply
Power is provided from an external AC adapter, and operation of the device (except Ethernet interface) is backed up by replaceable batteries. The device can be used permanently installed or as portable device with the option to charge batteries directly using the AC adapter or using standard alkaline batteries size AA. Battery life is several months.

Monitoring systems MS - models and variations
MS6D and its variations
Each Monitoring System contains 16 software configurable inputs.
MS55D
The user can select the hardware modules to be fitted into the monitoring system MS.
MS6-Rack - For mounting to 19“ rack
MS6R - MS6R - For deskopt use
| main differences | MS6D | MS55D |
|---|---|---|
| inputs | 16 software programmable inputs | 1 - 16 hardware input modules |
| maximum measured DC current | 20 mA dc | 5 A dc |
| maximum measured DC voltage | 10 V dc | 75 V dc |
| most sensitive measuring range of dc voltage | 18 mV dc | 100 mV dc |
| maximum measured AC current | - | 5 A dc |
| maximum measured AC voltage | - | 50 V ac |
| input for measurement of frequency | - | 0 to 5 kHz |
| input for counting of pulses | - | Yes |
Recording
Recorded values are stored to a non volatile electronic memory.
Various options for data recording
In addition to continuous recording mode with a constant interval can also enjoy a variety of other options. You can record data with its own interval only when certain conditions are valid, which may depend on measured values , time or direct user intervention. For example, you can control recording via an external contact or it is possible to set faster sampling mode during alarm conditions.
In case of power failure
In the event of a power failure, the backed up datalogger will continue to measure. Recorded data contains date and time of power failure. If the data logger is connected to GSM modem, the operator is immediately aware of difficulties.
Alarms and Communication interfaces
- Alerts via:
- » External siren or lights re
- » Email messages
- » SMS texts via connected
- GPRS modem or router
- » Telephone dialer
Relay on
Monitoring system MS activates selected relays (integrated relay ALARM OUT or external relays module) depending on alarm states.You can combine up to 16 switching external relay depending on arisen conditions. One of these conditions can be controlled via SMS messages.
Communication through GSM modem, GPRS / EDGE router
Modems can be used to set up a monitoring system MS, reading the recorded data, reading the current values and to communicate via SMS messages. The offered modems have been thoroughly tested to ensure maximum reliability.
Alerts via SMS texts
All data loggers are equipped with RS232 interface. GSM modem (GPRS router)
can be connected to that port for transmitting alarm SMS texts. Up to four phone numbers can be set. Using text messages
can also read the current values .
Email messages
Because of Ethernet interface you
can expand communication possibilities of measuring system MS. Then alarm emails are sent directly to your email inbox.
You can also read the current data via web browser.
