Accutech AM20 Acoustic Monitor Datasheet

The Accutech AM20 wireless acoustic monitor field unit is ideal for monitoring pressure relief valves, steam traps, automatic tank cleaning (CIP) systems, and other applications that generate ultrasound. It can also monitor on/off conditions of compressors and pumps, and is optimal for vapor/gas vent determination. The Acoustic Field Unit is suitable for compressible fluid applications.

The effectiveness of the acoustic measurement varies under different industrial environments, but has been demonstrated to work under the following conditions:

• Leak detection, steam: 30PSIG min.
• Leak detection, other gas: 50PSIG min.
• Leak rate: 6 standard cubic feet per hour (SCFH) at 100 PSIG min.

All Accutech field units automatically report field data to a centralised Accutech base radio over distances of up to 3000ft (~1000m). Each field unit is self contained, featuring an integrated 900MHz or 869MHz (license-free band), frequency hopping, spread-spectrum transceiver and antenna, and longlasting battery that offers 3+ years of maintenance-free service (up to 10 years depending on data rates and battery options).

Accutech networks are highly scalable with the possibility of 100 field units per base radio and 256 base radios per installation. Accutech field units are housed within a compact and weatherproof NEMA 4 enclosure with options for a remote sensor and remote antenna on select models. Field units are available in a wide range of certifications and are protected by an industryleading 3-Year warranty (parts and labor).
