Fits pressurized gas leak detection by sound where you need a Rosemount Incus (GDU-Incus)—ultrasonic acoustic detector with four sealed piezoceramic sensing heads, coverage about 40 m in low noise or 20 m in high noise, and 4–20 mA / HART outputs.
Key advantages
- Sensing — Four sealed piezoceramic ultrasonic heads (quad)
- Coverage — ~40 m low-noise (~54 dB); ~20 m high-noise (~74 dB)
- Response — Instantaneous (<1 s with HART; programmable delay)
- Outputs — 4–20 mA analog or stepped; HART; configurable relays
- Use — Pressurized gas leak acoustic detection
Typical applications
- Offshore / onshore gas modules.
- Compressor station leak monitoring.
- High-pressure process areas.
Selection guide
- Noise environment
- Relay / HART config
- Mounting height
Common mistakes
- Ignoring background ultrasonic noise.
- Coverage assumed in all directions equally.
- Alarm delay left at default wrongly.
When to RFQ / what to tell us
- Area noise class, options.
- Quantity, ship-to.
