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

Temperature probes Pt1000 (serie xxx/M)

Temperature/relative humidity probes with digital output (serie DIGI)

sensors

Sensors with bipolar output voltage and a range of- 60 to + 140 mV (heat flux sensors, etc.)

devices with two-state output

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.

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

Measuring and recording system MS has been developed to meet all requirements for the possibility of alarming. Each of the 16 channels offers setting of hysteresis, a delay and up to four conditions to active alarm. Alarm can be presented as sound (buzzer) and as visual signal (LED 1-32). For each alarm you can assign actions to be performed.
  • Alerts via:

  • » External siren or lights
  • re
  • » Email messages
  • » SMS texts via connected
  •    GPRS modem or router
  • » Telephone dialer
data logger

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.

Common connectivity options

Monitoring system MS may be configured for almost any desired measurement application. Sensors can be wired to datalogger in star-like connection as well as in serial. Combination of both is also possible. The monitoring system MS is characterized by a wide range of communication interfaces such as the RS232, RS485, USB, Ethernet and GSM or GPRS modem. Thanks to Wi-Fi routers several measuring systems MS can be wirelessly connected to a network.
