MSA Brand leak detector Model Surveyor Ultrasonic

Description

The Surveyor is a non-concentration based gas detector used to detect leaks from high pressure systems.

Like other ultrasonic gas monitors, the Surveyor responds to the airborne ultrasound generated from gas releases in open,

well ventilated areas, where traditional methods of detection may be unsuitable or dependent on ventilation.

Because the Surveyor responds to the source of a gas release rather than the dispersed gas,

it is unaffected by changing wind directions, gas dilution, and the direction of the gas leak. Further, with its maximum coverage radius of 20 meters,

it can supervise a relatively large area with a single device.

The Surveyor is immune to many false signals and can be configured to filter short timescale ultrasonic noise that can produce nuisance alarms.

Frequencies below 25 kHz are removed by a high pass filter, effectively eliminating interference from audible and low frequency ultrasonic noise.

At the same time, setting the alarm trigger level above the ultrasonic background noise ensures immunity to other noise sources.

The result is a reliable method of detection, able to monitor environments with high levels of ultrasound such as turbine rooms and compressor stations.

Besides high-pressure gas applications, the Surveyor is suited for installations restricted to low power (< 1 W).
