SK-203 RF capacitor boiler water level transmitterDetailed product description：

Principle
By placing the RF capacitor in the measured liquid through a feeder, the change in liquid level can be detected by the absorption value of the RF radiation as the liquid level height changes. Due to the significant difference in the absorption of radio frequency radiation between liquid and vapor phases, while temperature, pressure, medium, and specific gravity have little effect, this transmitter is more accurate in detecting liquid levels than differential pressure transmitters and electric float level transmitters. It is also cheaper and more advanced than the combination of electric contact level gauges and dual color level gauges.

Characteristics
Our unit has recently developed a technology that combines an RF capacitive liquid level transmitter with an on-site boiler water level gauge. By taking advantage of the intuitive features of the on-site water level gauge and the ability to remotely transmit and process the signal from the liquid level transmitter, and using one signal to control the luminous display on site, an SK RF capacitive boiler water level transmitter can achieve two principles of measurement and three types of measurement
The purpose of display. Namely:
⑴. Visual display of on-site water level (by viewing the water level through a glass window and calibrating the remote transmission signal);
⑵ On site water level luminous display (clear red and green through the luminous display, with an observation range of up to 30 meters, especially suitable for dark and dusty occasions);
⑶ Remote signals can be transmitted to the control room and controlled through instruments and computers.
