Description

The wireless pressure gauge is a key component of the AKS FieldPORT™ wireless monitoring systems. There are a wide variety of pressure ranges available with more on the way. Each gauge is fully characterized over temperature providing outstanding performance at a reasonable price. Each gauge is self-powered and contains a pressure sensor, signal conditioning circuitry and an RF transceiver operating in the 902 MHz to 928 MHz ISM license-free band. Remote mount sensors and high-gain antennas are available as options for the gauge pressure units.

Data from the sensor are transmitted to a Base Radio Logger for centralized monitoring and data acquisition. You may specify updates between once per second and once per minute based on how frequently the process is monitored and how often the data is transmitted.
