WWDP series differential pressure
transmitter for liquid
product manual:
Selectable range, optional output signal
Although there are only three models of WWDP series differential pressure
transmitters for liquids, each model has thirty functions that can be selected on site. The WWDP series can select single vector path or bidirectional positive and negative range on the spot, and can select the output signals of 0-5, 1-5, 0-10VDC, and 4-20 mA. It also has the function of automatic zero calibration. The function of high and low pressure interface can be selected on site, and it is not necessary to reinstall for the wrong installation direction on site. Optional LCD display for on-site instructions and simultaneous output of signals. The degree of protection of the cast aluminum enclosure is NEMA 4 (IP66). These functions make WWDP differential pressure
transmitters widely used for monitoring gas, liquid flow,
filter pressure drop, liquid level in pressure vessels, etc. in energy management systems or process control systems.
