| measuring range: | -10.0 mbar to +420.0 mbar (-7.5 mmHg to +315.0 mmHg) |
| overload: | max. 1 bar |
| resolution: | 0.1 mbar (0.1 mm Hg) |
| additional pressure units: | bar, kPa, MPa, PSI, mH2O |
| accuracy (typ. values): | hysteresis and linearity: ±0.1 % FS temperature influence from 0 to 50°C: ±0.4 % FS option higher accuracy available: already integrated |
| pressure connections: | 2 |
| display: | 2x 4½-digit LCD |
| sensor: |
Piezoresistive differential pressure sensor internally built into the instrument. Suitable for air and non-aggressive gases. (Note: not suited for water!) |
| pressure connection: | 2 universal pressure ports for 6 x 1 mm (4 mm internal diameter of tube) or 8 x 1 mm (6 mm internal diameter of tube) plastic tubes |
| output: | interface or AAG |
| serial interface: | yes |
| analog output: | 0 V to 1 V, freely scalable (resolution 12 bit) |
| power supply: | 9 V battery, mains adapter |
| sensor adjustment: | digital offset and scale input |
| peak value memory: | ≥1 ms |
| measuring cycle: | "slow": 4 measurements / s "fast": (with filter): ≥1,000 measurements / s „peak-detect“ (peak value memory): ≥1,000 measurements / s The min- / max- value memory stores unfiltered pressure peaks ≥1 ms. |
| averaging function: | Integrates the meas. values during a selectable period of time and then calculates the average display value. |
| low power logger mode: | (only in measuring cycle „slow“) Only one measurement carried out at the end of the respective logger cycle. The battery life is considerably prolonged. For long-term recordings (e.g. leaktest). |
| controlling function: | with the help of the switching module GAM3000 (optionally) external devices can be controled (switch on/off) or alarm monitored |
| logger functions: | - manual: 99 data sets - cyclic: 10,000 data sets (max. 64 recording sequences), adjustable cycle time: 1 s to 3,600 s |
| battery life: | approx. 500 h (slow mode) approx. 120 h (fast = 1,000 Hz) |
| working conditions: | -25°C to +50°C, 0 % to +95 % r.h. (non-condensing) construction type EX: -10°C to +50°C, 0 % to 95 % r.h. (non-condensing) |
| housing: | 142 x 71 x 26 mm (H x W x D) (without pressure connection pin - pin approx. 16 mm protruding at front side of device), impact-resistant ABS, membrane keypad, transparent panel, integrated pop-up clip |
| weight: | approx. 170 g construction type EX: approx. 210 g (incl. leather case) |
EX qualification: II 2 G Ex ib IIC T4 Gb
