DR72 Digital manometer


The DR72 can be used as process manometer/vacuometer and reference standard instrument in calibration tasks. It incorporates a pressure sensor with ranges from vacuum to 350 bar. Datalogger, digital and analog output.

The DR72 series of digital manometers offers a dual alternative of use: process manometer/vacuometer on the one hand, reference standard instrument in calibration tasks on the other. The equipment incorporates a pressure sensor with overlapping ranges from vacuum to 350 bar. The material in contact is aluminium for pressures above 1 bar and therefore admits liquids or gases compatible with that material. For lower pressures it is only suitable for inert gases.

The DR72 series is equipped with a front cover that incorporates a tactile button panel for on/off/zero/configuration states. The manometer offers a wide range of functionalities such as auto power off time, maximum and minimum readings, change of engineering units, tare, alarms, password and additional functions configurable from the keypad itself.

The pressure gauge is encapsulated in a aluminium IP67 box 110 mm in diameter with housing for three AA size batteries that illuminate a large LED display of 350 segments for a numerical and alphanumeric indication backlit at will with LED and high visibility.

It has an external 24 Vdc power input to facilitate its installation in process. In addition, the DR72 can be supplied with a 4-20 mA analog output or configured as a slave in a network of sensors connected via MODBUS RTU RS-485 protocol, which gives the DR72 perfect scalability in distributed control systems (DCS).

Available types of pressure: relative pressure, absolute pressure, vacuum, combined ranges, differential pressure.
