LF620 and LF622 Magnetic Flowmeter Signal Converter
Multi-functional converter LF620 (Integral) and LF622 (Remote) equipped with its patented Noise-Sentry original noise- suppression circuit and advanced algorithms. IR (Infrared) switches enable parameter setting of the converter without removing the cover. Flow direction can be set in either way, and its unique 128 x 128 dot matrix LCD display allows the LCD to be rotated electronically to 90, 180 and 270 degrees without opening the cover.
• HART protocol (Highway Addressable Remote Transducer) is a communication protocol for industrial sensors recommended by the HCF (HART Communication Foundation).
• DevComm2000 Smart Device Communicator available for performing HART device configurations on PC or laptop is available through the supplier.
• PROFIBUS is the communications protocol for factory and process automation that the PROFIBUS Organization recommends. Instead of analog control with a conventional analog signal (4-20 mA), it is fieldbus which digitizes all signals. Flowmeters support PROFIBUS-PA.
• Modbus is the communication protocol that Modicon Inc. developed. Physical layer is RS485.
