Product Details ofVLF-219 Pressure Transmitter
Product description
VLF-219 pressure transmitter adopts the diffused silicon pressure sensor core of the internationally famous company, and converts the pressure of the measured medium into 4~20mA, 0~10VDC analog signals and IIC, RS485 and other standard digital signals through the highly reliable amplifying circuit and precision digital temperature compensation and nonlinear correction technology. Self -opening waterproof plug with fully sealed welding process to ensure excellent quality and best performance. Users can easily, quickly and accurately measure the pressure of all kinds of fluids. The ultra-high cost performance can be widely used in petroleum, chemical industry, metallurgy, electric power, frequency conversion pump, complete water supply, refrigeration, air conditioning, air compressor and other fields.
