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

  • 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.

We have a full range of diaphragm seal to go with this digital pressure gauge. 

Feature Highlights 


The instrument is equipped with single volt-free changeover-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.


DM650PM 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 process value, 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. The USB configuration 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.


5-point calibration can be applied using the USBSpeedLink software. As well as straight line interpolation, up to 22 points (x,y) of user-linearisation are available for creating custom curves and corrections.


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