Robust telemetry architectures designed for hazardous area (Ex ia) integration for chemical processing, hydrocarbon refining, and pressurized midstream transport. Detects micro-fissure valve passing, steam trap blow-through, slurry pump cavitation, and piping stress vibrations complements API 670 machinery protection systems and fugitive-emissions monitoring programs.
High-pressure steam and toxic gas passing through worn valve seats generates high-frequency acoustic turbulence. Our wideband acoustic sensors (20 Hz to 10 kHz) continuously monitor valve bodies and steam traps non-invasively, designed to detect small leaks (application-dependent) without drilling pipe walls or halting production.
Aggressive chemical slurries and high-pressure sour gas subject centrifugal pumps, blowers, and reciprocating compressors to continuous cavitation, mechanical seal failure, and bearing fatigue. Synchronous tri-axial acceleration up to 25.6 kS/s calculates ISO 20816-3 velocity RMS and envelope spectra directly on-sensor.
Process plants span vast distances where pulling new industrial Ethernet conduit is cost-prohibitive. Using 10BASE-T1L Single Pair Ethernet (SPE), our nodes transmit deterministic IP telemetry and bus power over existing single-pair instrumentation wiring across runs up to 1000 meters.
Continuous acoustic sensing records automated valve sealing verification logs, supporting plant operators' LDAR (Leak Detection and Repair) programs. Standard interfaces connect via OPC UA and Modbus to plant DCS and SCADA platforms such as Emerson DeltaV, Yokogawa Centum, and Foxboro.
