Features
Applications
Testo 6445-1 is used for continuous leak detection in industrial companies.
| Sensor | Thermal silicone chip sensor, mass flow principle |
| Media | Compressed air, air, nitrogen, non-corrosive gases (attention: areas with explosion hazard not permitted) |
| Measuring range | 0 to 80 Nm/s, min. 1 Nm/s (0699 6445 / 1) or 0 to 150 Nm/s, min. 2 Nm/s (0699 6445 / 2) |
| Accuracy | ± 3% of actual value ± 0.4% of final value |
| Pressure dependency | Measuring principle pressure-independent (Mass flow measurement). For flow velocities < 10 Nm/s: pressure influence 0.3 % of value per bar |
| Temperature dependency | Compensated at 25° C, differing temperatures: 0.1% of value |
| Reaction time | t90 approx. 5 seconds |
| Voltage supply | 12 to 24 VDC ± 10%, current consumption < 100 mA (Starting current 500 mA for a short period) |
| Electrical connection | Precision plug connection and 10 metres of cable are included in delivery of the compressed air counter 0699 6445 /1 and 2 |
| Analog output | 4 to 20 mA = 0 to 80 or 0 to 150 Nm/s, 4-wire, max. load = 500 Ohm, max. length 250 m (use shielded cable!) |
| Digital output | RS232, max. cable length 15 metres, in combination with junction box |
| Ambient temperature | -10 to +60° C |
| Storage temperature | -40 to +80° C. Frost is to be avoided |
| Weight | Compressed air counter: 840 g, display: 140 g, 10 metres of cable: 640 g, screwed clamping ring: 100 g |
| Housing | Aluminium, painted, IP 65, however permitted only for interior installation |
