displacement level transmitter adopts stress measuring method by applying the lever principle.
displacement level transmitter adopts stress measuring method by applying the lever principle to acquires the signal being consistent with fluid level change and being measured through high precision spectacles cantilever stress sensor. Via being processed by A/D converter, MPU and D/A converter, the measured signal is transferred into 4-20mA analog signal and digital signal that is conformity with HART PROTOCOL and is superimposed on the analog signal, and then the processed signal is output. It is provided with the function of highly accuracy for linearity treatment, strong interfere- resistance, remote configuration, checking, maintenance and adjustment. This meter can work together with equipment being conformity with HART protocol in the field bus so as to realize the digital two-way communication, process checking and automatic controlling. It also is compatible with analog meter. It features pretty external appearance as its fashionable shell structure design. This structure makes each chamber separately to make the meter more reliable and safe. Also the meter is added a precise static pressure adjustment device so as to keep high precision and reliability. Both shell structure design and the static pressure adjustment device have been granted the national patents.
The patent number for external appearance design: 99 3 21507.6
The patent number for static pressure adjustment device: 99 2 23728.9
PerformancesLCD display: field display related variables
Local and remote configuration function: through the magnetic switch in the transmitters head, or a handle communicator or a computer with commissioning software to read and write and configure all kinds of process variables, the signal (4~20mA)on which every parameter and variables being conformity with HART protocol
