Accuracy

0.1 % of sensor URL including combined effects of linearity, hysteresis, repeatability and temperature (applies to standard unit without isolating seals)
NOTE: addition of seals will reduce accuracy due to thermal effects of fill fluid.

Stability

Combined zero and span stability: less than 0.1% of sensor URL per year at 70°F

Gauge Pressure Field Unit Description

Output Resolution

The Gauge Pressure Field Unit is self powered and contains a pressure sensor, signal conditioning circuitry and a 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. The field units are completely free of field wiring for power and signal transmission, making them ideal for automating remote pressure monitoring in all types of industrial environments. Data from the sensor is transmitted to the Base Radio for centralized monitoring and data acquisition. The user may specify sample and transmit updates between once per second and once per minute. Transmit rate changes can also be triggered based on events that are defined in terms of measurement limits or rates of movement. This function allows for maximization of battery life while ensuring that all important process events are monitored. A variety of seals are available for applications that require them including sanitary clamp seals for pharmaceutical, food and beverage process areas. 24 bit Analog to Digital conversion - see specification sheets for the Base Radio and Analog Output Modules for descriptions of analog and digital output options.
