The DM650TM digital temperature gauge accepts RTD or thermocouple temperature sensors and displays the sensor temperature in °C or °F 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. In addition to this, on board datalogging is also available.
FEATURE HIGHLIGHTS
RELAY SWITCHING
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.
