DM670TM

Temperature gauge with data logging, dual alarm & messaging.

The DM670TM is a large digital temperature gauge. It 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 two changeover relays 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 to record process details up to 5000 points.

FEATURE HIGHLIGHTS

DUAL RELAYS
The instrument is equipped with 2 volt-free changeover-type relays, operating independently. The user
may select one of seven actions, including deviation, latched or non-latched operation, with fully
adjustable set-point and hysteresis. The Relays may be turned off if not required to extend battery life.
An option is provided to trigger an alert-event when a relay contact is on.

DATA LOGGING FUNCTION
The large digit 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 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 for export to other programmes. While 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 3.6 V lithium battery. The battery life is dependent on the number
of active features such as the relay contacts and alert LED. Battery life 1 year minimum (longer depending
on options selected)

REAL-TIME CLOCK
Date and time-stamped maximum, minimum and average temperature values, as well as relay on and
relay off data, is recorded and can be displayed along with the current time and date. The RTC is also
used to record the data logged points.
