DL3351 intelligent transmitter
Uses: can be widely used in petroleum / chemical / electrical / wastewater treatment / metallurgy / pharmaceutical / paper / machinery / shipbuilding and other industries
Detailed introduction
DL3351 the use of a new generation of intelligent transmitter of advanced digital technology, the direct digital capacitance circuit in principle to replace the analog signal amplifying circuit and A/D conversion circuit, the digital compensation technology to compensate for temperature, pressure, improve the measurement accuracy, temperature drift reduction. The series transmitter has the characteristics of small size, high reliability and good long-term stability. With a high price and become the mainstream product transmitter market, can be widely used in oil / Petrochemical / chemical, electricity / gas / other company city utilities, pulp and paper, steel, nonferrous metal / ceramic / mechanical / shipbuilding industry. Features: use the microprocessor to increase flexibility, strong function; range covers: 0-0.12KPa ~ 41.37MPa; the accuracy is better than 0.1% + 0.075% range is better than 40:1; have strong self diagnosis ability; zero and span adjustments do not affect each other; both remote and local range, zero adjustment; second, in line with the HART protocol, and type ROSE-MOUNT275 and HART375 manipulator for digital communication and analog output terminal; sensor with nonvolatile memory; good stability, high precision, adjustable damping, one-way anti overload ability; all general parts, sensors and electronic exchange board does not affect its characteristics, maintenance is convenient; the diaphragm material contact medium optional explosion-proof structure of excess housing.
