- Description
- Specifications
Acoustic Resonant Transducers (ARP) are designed to measure pre-explosive concentrations of methane, ethane, propane, butane, isobutane, pentane, cyclopentane, hexane, hydrogen, benzene, ammonia in air, the volume fraction of carbon dioxide, 12 and 22 refrigerants, and sulphur hexafluoride (SF6), as well as alarm about the presence of combustible gases and vapours and their mixtures in air, as well as hazardous concentrations of refrigerants, and the transmission of the measurement information to the external devices.
ARP can be operated in environments containing halogens and other catalytic poisons. ARPs are used both as acoustic gas detectors, as well as part of gas detecting, or process control systems.
