Delphin LogMessage Connectivity

Secure data storage

The LogMessage's data storage capability enables it to function without PC or network support.

  • Measurement data can be assigned to groups and used as triggers
  • No data loss in the event of power failure
  • Alarm management with pre and post alarm data

Comprehensive signal processing

Software channels, configurable according to requirements, can be used for online calculation, monitoring, and many other functions. This enables data to be generated that is immediately usable.

  • Online calculations performed on measurement data (e.g. temperature differentials)
  • Integration functions (e.g. flows to volumes)
  • Limit value monitoring with alarm functions (switching digital outputs)
  • Counter function and operational data acquisition

Galvanic isolation included

LogMessage devices are fully protected against earth loops enabling measurements from non-isolated sources.

  • All analog inputs can function as differential inputs
  • Isolation voltage between analog inputs: 110 VDC to a maximum of 650 VDC Galvanic isolation between power supply and each interface
  • No earth loop problems

Resolutions for demanding requirements

LogMessage devices are suitable for both slow- and high-speed measurements. Time resolution for analog measurement data is at 100-µs precision levels; digital resolution at millisecond precision. The devices are equipped for precision measurement with 24-Bit ADCs.

Web server included

LogMessage devices are equipped with internal web servers. The standard version displays current measurement data in a channel list as well as extensive configuration and maintenance   information.

Software channels

Software channels are capable of performing computations on online measurement data, and used for visualisation, storage or monitoring purposes. The processing of signals takes place independently within the LogMessage device and requires no PC support. There is virtually no limit on the number of software channels that can be used. Software channel computations run parallel to data acquisition and logging. Software channels are included in delivery

Versions

LogMessage devices are available in nine different versions. The versions differ in the number of inputs and outputs. All versions are identical in respect of interface options, internal functions, galvanic isolation and data logger memory. LogMessage is available in nine different versions. LogMessage is a genuine high-speed logger with sampling rates of up to 10,000 measurements per second.

The LM 5000 version has an increased isolation voltage of up to 650 VDC between inputs.
