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. The equipment 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 faceplate that incorporates a tactile keypad for on/off/zero/setup 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 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 installation in the process. In addition, the DR72 can be supplied with a 4-20 mA analog output or configured as a slave in a sensor network connected via MODBUS RTU RS-485 protocol, which gives the DR72 perfect scalability in distributed control systems (DCS).
