Net Safety Monitoring has announced the addition of the Banshee343 ultrasonic gas-leak detector to its advanced flame and gas detection product portfolio.

The product is designed to provide reliable, wide-area gas detection (toxic and/or combustible) coverage in any hazardous-area application where pressurised gas is present – regardless of the environmental conditions.

Ultrasonic gas-leak detection is commonly utilised together with traditional fixed detection technologies as a first line of defence against dangerous gas-leak situations in oil and gas installations.

It offers several performance advantages, according to Net Safety Monitoring.

It does not have to wait until a gas concentration has accumulated to potentially dangerous concentrations; it offers a wide area of coverage; it does not require a gas cloud to eventually make physical contact with a sensor; and the response is instantaneous for all gas types.

The Banshee343 ultrasonic gas-leak detector only triggers an alarm when inaudible ultrasound is detected (between 25-100kHz) which is only produced with the release of highly pressurised gas.

This makes for reliable and efficient performance by the detection system as there is no poisoning of sensors, it never requires field calibration, and all background noises are effectively filtered.

The available analogue, relay or modbus outputs can communicate directly with any existing plant control system (DCS, PL/PLC, Fireandgas panel, or Scada).

Mike Nugent, vice-president of sales and marketing at Net Safety Monitoring, said: ‘The speed of response with ultrasonic technologies can bridge the dangerous gap between gas detection in difficult conditions and the actual ignition of gas, when flame detection offers the final opportunity for automatic detection/reaction.

‘When ultrasonic gas-leak detection is combined with advanced fixed gas, flame and smoke/oil mist detection, comprehensive safety coverage for end users is ensured,’ he added.

The Banshee343 is said to offer several advantages over competitive ultrasonic gas-leak detection solutions: factory-tuned sensors are calibrated for life; four piezoelectric sensor heads are sealed in a virtually indestructible ceramic housing and have no moving parts; a wider and more reliable coverage area (four independent sensor heads – 20m radius, approximately 1,600m2 from centre); and the Soniccal Diagnostic system, which automatically cleans the sensor head and gives a true ultrasonic broadband self-test every 15min to confirm continuous operation.

Net Safety Monitoring offers full onsite sound mapping surveying and detector allocation, onsite commissioning assistance, and will provide personnel with training and testing equipment.

The Banshee343 detects deadly gas leaks at the speed of sound without being affected by inclement weather, wind direction, leak direction or any potential gas dilution.
