This is the first radio frequency capacitive continuous measure level transmitter. By adopting the special chip designed by ourselves, it's the first time to complement demarcate by feeding once. It's a perfect union of low cost and powerful functions. Presenting our company advance with time. The level transmitter is constituted by sensor and secondary instrument. The probe is extended to the bam, while the secondary instrument is placed in other suitable area. The level changes are converted to proportional electrical impulse and remote transmitted to secondary instrument. With streamers display the level, upper/lower limit alarm and 4-20mA transmit output. It's suitable for liquid and solid materials' level display, control, alarm and remote transmission or system constitusion.
