Wireless Multi-Input Field Unit

Ideal for adding wireless capabilities to existing or new wired measurement sensors such as radar tank gauges, flow meters and chemical analyzers, the Accutech AI10 and AV10 wireless multi-input field units provide dual analog inputs in either current (4-20mA) or voltage (0-10V) configurations. Each unit also includes two discrete contact closure inputs for simple apparatus use.


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 2.4GHz (license-free band), frequency hopping, spread-spectrum transceiver and antenna, and long-lasting 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 weather-resistant NEMA4 enclosure with options for a remote sensor and remote antenna on select models. Field units are available in a wide range of certifications and come with a 3-Year warranty.
