DIGITAL TEST GAUGE

nnnn

The all new DX digital gauge from Budenberg is designed to

nnnn

offer a truly simple, cost effective digital gauge to cover a wide

nnnn

range of applications from calibration laboratory to in-field use.

nnnn

The DX is offered in a choice of standard ranges up to 700 bar

nnnn

in conformance with the EN-837 standard. Alternatively units

nnnn

can be factory programmed to offer the precise range and

nnnn

pressure units required for any particular application.

nnnn

Based around a high specification Peizoresistive silicon sensor,

nnnn

the DX has an accuracy of 0.1 % of the calibrated span which

nnnn

is fully temperature compensated across the range of -10 to 50

nnnn

Deg C thereby allowing accurate readings to be taken over a

nnnn

wide range of ambient conditions.

nnnn

The unit has a large five digit LCD display that incorporates a

nnnn

vertical bar graph to indicate the %age of the range being

nnnn

displayed. Menu keys allow the user to define or reconfigure

nnnn

the mode and characteristics of operation if required.

nnnn

Dial Size

nnnn

86 mm (3.4")

nnnn

Mounting

nnnn

Direct

nnnn

Connection

nnnn

1/4" NPT or BSP male connection in 316 stainless steel.

nnnn

An integral filter in the inlet prevents the ingress of solids whilst

nnnn

an in-built oil filled isolation seal protects the sensor.

nnnn

Compatibility

nnnn

All liquids and gases compatible with 316 Stainless Steel

nnnn

Scale Ranges

nnnn

Ranges from Vacuum to 700 bar can be provided in either

nnnn

standard ranges as defined in EN-837 or specially programmed

nnnn

to suit the requirement. (Please see overleaf).

nnnn

Pressure Scales

nnnn

psig, bar, mbar, kPa, Mpa, mmHg, "H20, "Hg, mmH20, mH20,

nnnn

Kg/cm2. Two active pressure units can be pre-programmed

nnnn

at the factory or user selectable via the menu keys.

nnnn

Accuracy

nnnn

0.1 % of calibrated span on all pressure scales and units

nnnn

0.25% of vacuum range of-14.5 to 0 psig

nnnn

All units may be safely used to measure vacuum, but only units

nnnn

with a calibrated range of 0-7 bar or less will be rated and

nnnn

tested for vacuum operation

nnnn

Temperature

nnnn

Operating & Compensated: -10 °C to +50 °C

nnnn

Storage: -40 °C to +70 °C

Over Scale Range

nnnn

The DXwill read up to 10% above the selected primary pressure

nnnn

range

nnnn

Overpressure capability

nnnn

-1 to +7 bar ranges then max overpressure is 21 bar

nnnn

7 to 70 bar ranges then max overpressure is 140 bar

nnnn

70 to 0-700 bar ranges then max overpressure is 1400 bar

nnnn

Display

nnnn

Large five full seven-segment LCD digits, digit height = 0.66"

nnnn

Internal resolution always exceeds the displayed resolution

nnnn

Display rate - 4 readings per second

nnnn

Vertical Bar Chart to show %age of scale
