The DR72 series of digital pressure gauges offers a double alternative of use: process pressure/vacuum gauge on the one hand, reference standard instrument in calibration tasks, on the other hand. Its accuracy, time stability, autonomy and communications characteristics make it the ideal instrument for a wide range of industrial applications.

The instrument incorporates a pressure sensor with overlapping ranges from vacuum to 350 bar. The material in contact is AISI 316 stainless steel for pressures above 1 bar and therefore accepts liquids or gases compatible with this material. For lower pressures it is only suitable for inert gases. The DR72 series is provided with a front cover that incorporates a touch button panel for on/off/zero/setting status.

The gauge offers a wide range of functionalities such as auto-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 110 mm diameter 316 stainless steel case with a housing for three AA-size batteries that illuminate a large 350-segment LED display for numeric and alphanumeric indication, backlit with LEDs as desired and highly visible. It has an external 24 Vdc power input for easy in-process installation. In addition, the DR72 can be supplied with 4-20 mA analog output or configured as a slave in a network of sensors connected via MODBUS RTU RS-485 protocol, giving the DR72 perfect scalability in distributed control systems (DCS).
