Description

The wireless level gauge is a key component of the AKS FieldPORT™ wireless monitoring systems. The temperature gauge comes in both RTD and thermocouple versions. The selection of sensor type depends on the AKS Technologies package that is selected and the specific measurement required.

Each gauge is self-powered and contains a temperature sensor, signal conditioning circuitry and ar 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. Sensor lengths may be selected aid options for weld or spring-Ioad are available.

Data from the sensor are transmitted to the Base Rad 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.
