Smart transmitters have higher accuracy and precision along with faster dynamic response than the analogue ones. This will give the smart models an advantage to produce tighter process control.
Smart transmitters can be configured and serviced in the field or from a remote location, such as the control room, along the 4-20 mA line. This ease of field service can be very important to quick field troubleshooting and improves maintenance issues.
Smart transmitters communicate through HARTTM (Highway Addressable Remote Transducer) protocol, a platform ready for complete digital integration of your process system. The HART communication protocol is capable of performing simultaneous analogue and digital communications. HART protocol allows multi-drop instrument installation, operation over remote telephone communication lines and transmission of multiple variables when operating digitally.
PAKKENS Smart Pressure Transmitters are two-wire microprocessor-based instruments, which can receive a pressure lines, and indicate the value of the fluid pressure on its LCD display, and generate a 4-20 mA output signal directly or inversely proportional to the pressure of the input lines. Digital communication for remote calibration and monitoring is also provided, superimposing a digital signal on the same pair of wires that carries the 4-20 mA signal.
PAKKENS Smart Series utilize the proven piezo resistive silicon technology. Deflections of the diaphragms under pressure are transferred by a manometric fluid to the sensor to produce very highly accurate measurements.
Thermal drift is automatically compensated using the signal from an integrated thermistor into the pressure sensor. The high accuracy sensor coupled with the temperature compensation feature has a measurement precision,
Due to the materials and technology used in the construction of these pressure transmitters, instruments are excellent in reliability, resistance to corrosion against the majority of chemically aggressive media and withstanding mechanical shocks.
