DM650/HM : Humidity & Temperature Gauge With Data Logging, Alarm & Messaging

  • %rh, temperature, dew point, delta t
  • Alarm relay / user set display messaging
  • Usb and nfc interface
  • Battery powered
  • 5000 point data logger

The DM650HM humidity gauge has been designed to display % relative humidity, temperature, dew point and delta temperature, on a 6- digit LCD display. The instrument offers an advanced display-mode, allowing the user to display not only process variables but one or two (1 – 32) character messages. This feature is further enhanced by the ability to split a process range into eight user-set bands, each band having independent user selected messages. The DM650HM also has a changeover-type relay with multiple programmable options allowing the user to set a high, low or deviation alarm.  Wall and duct-mounted versions are available.

FEATURE HIGHLIGHTS

RELAY
The instrument is equipped with single volt-free change-over type relay. The user may select one of
several actions, including deviation operation, with fully adjustable set-point and dead-band. An option is
provided to trigger an alert-event when a relay contact is on. The relay can be used to alarm on any of the values of relative humidity, temperature, dewpoint or delta temperature. A battery-monitoring function is also provided.

DATA LOGGING FUNCTION
DM650HM humidity gauge also provides a powerful data logging-function. The log points can be set up to 5000 points, each
point is time and date stamped together with %RH, temperature and relay-state information.
The log rate is selectable in steps. The start of log can be delayed if required. Either fixed or rolling logs
may be performed.
Two methods of reading the log are available. The USB configuration reads the log and allows the user to
save to a text file. The NFC android interface allows data transfer to compatible android phones or
tablets; by using the downloadable App, the data can be graphed and forwarded by email, Bluetooth etc.
The NFC interface is also capable of starting a new log with different log periods and modes.

FLEXIBLE DISPLAY OPTIONS
The DM650HM can display any combination of the following process variables: % relative humidity,
temperature, dew point and delta temperature.

REAL-TIME CLOCK
Date and time can also be displayed with the input values. The real-time clock is used to record the data
logged points

In addition to this, on board datalogging is also available to record process details at up to 5000 points.

FEATURE HIGHLIGHTS

RELAY TRIP
The instrument is equipped with a volt-free changeover type relay. The user may select one of seven
actions, including deviation operation, with fully adjustable set-point and hysteresis. The Relay may be
turned off if not required to extend battery life. An option is provided to trigger a display alert-event
when the relay contact is on. The relay can optionally be used to indicate a low battery condition.

DATA LOGGING FUNCTION
The digital temperature gauge also provides a powerful data logging function. The log points can be set up to 5000 points, each point is time and date stamped together with temperature and relay state information.
The log rate can be selected in steps. The start of log can be delayed if required. Either fixed or rolling logs
may be performed. Two methods of reading the log are available. USB interfaced software reads the log and allows the user
to save to a text file for export to other programs. The NFC android interface allows data transfer to
compatible android phones or tablets by using the downloadable App. The data can be graphed and
forwarded by email, Bluetooth etc. The NFC interface is also capable of starting a new log with different
log period and modes.

BATTERY POWERED
The instrument is powered by a single AA 3.6 V lithium battery. The battery life is dependent on the
number of active features such as the relay contact and alert LED. Battery life 1-year minimum (longer
depending on options selected)

REAL-TIME CLOCK (RTC)
Date and time can also be displayed with the input temperature. The RTC is also used to time stamp the
data logged points which will also give relay state.

DM650/PM : Digital Pressure & Temperature Gauge With Data Logging, Alarm & Message Display

  • Pressure/ temperature gauge
  • Gauge or Absolute pressure
  • High accuracy
  • Alarm relay, max/ min information
  • 5000 point data logger with usb and nfc interface

The DM650PM battery powered digital pressure gauge accepts gauge or absolute pressure and displays the gauge or absolute sensor pressure in BAR, PSI or the user’s engineering unit on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert event to occur when the pressure is within a band. A change-over relay can be used together with the messaging and alerts to provide switching at user set points. In addition to this, on board data-logging is also available to record process details at up to 5000 points.

DM650/LP : Loop Powered Indicator With Data Logging, Alarm & Message Display

  • (4 to 20) mA LOOP POWERED
  • CAN BE USED AS A LOOP POWERED PROCESS SWITCH
  • USE ON TOP OF TEMPERATURE PROBE OR SURFACE MOUNTED
  • USB AND NFC INTERFACE
  • BATTERY BACKUP
  • 5000 POINT DATA LOGGER
  • ABS PLASTIC, STAINLESS OR ALUMINIUM HOUSING

The DM650LP loop powered process switch and indicator, accepts a (4 to 20) mA signal and displays the process value in the appropriate engineering units on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages.

Additional to the messages, the user may select an alert event to occur when the temperature is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user set switch points. This means the instruments can be used as a loop powered process switch depending on which type of process the (4 to 20) mA loop is measuring. For example temperature or pressure.

In addition to this, an on board datalog function is also available to record process details at up to 5000 points. In this case a battery needs to be fitted so the log can continue to be monitored in case of loop failure. The battery life is dependent on the number of active features such as the alert LED and logging options. Battery life 2-year minimum (longer depending on options selected).

LOOP POWERED The instrument is powered by the loop current. A single AA 3.6V lithium battery is also fitted to allow display function and datalogging to continue on mA loop current loss. This is useful for displaying error messages and maintains the log function, allowing the user to determine the loop loss period.

RELAY TRIP The instrument is equipped with a volt-free changeover-type relay. The user may select one of several actions, including deviation operation, with adjustable set point and hysteresis. The Relay may be turned off if not required. An option is provided to trigger a display alert-event when the relay contact is on.

DATA LOGGING FUNCTION DM650LP also provides a powerful data logging function. The number of log points can be set up to 5000; each point is time and date-stamped together with input process value (PV) and relay state information. The log rate is selectable in steps. The start of log can be delayed if required. Either fixed or rolling logs may be performed.

Two methods of reading the log are available. USB interfaced software reads the log and allows the user to save to a text file for export to other programmes. The NFC android interface allows data transfer to compatible android phones or tablets by using the downloadable App. The data can be graphed and forwarded by email, Bluetooth etc. The NFC interface is also capable of starting a new log with different log period and modes via the Android app.

TEMPERATURE TRANSMITTER COMPATIBLE As well as working with any (4 to 20) mA signal the DM650LP has space inside its housing to mount a Status Instruments (4 to 20) mA temperature transmitter. Our range of temperature transmitters can be used with the DM650LP in the SCH4 housing to give a local temperature display.
