- Key Products/Technologies
- The main product lines include level switches, level transmitters, flow switches, and other sensors. Level switches are ON/OFF control solutions utilizing the principle of float buoyancy and the opening/closing of a reed switch. Representative models using this principle include DFR, DC, and DQ. Designed to be compact and lightweight, these sensors are applicable in various environments and offer customizable production capable of up to 4-point contact signal output. Technical specifications include an operating temperature range of -40℃ to 100℃, a maximum pressure of 10 kgf/㎠, SPST signal output, connection ratings of 5VDC 0.5A / 220VAC 1A, and insulation resistance of 500 MΩ (min.). Stem, socket, and float materials are SUS304 (option SUS316), with the head made of aluminum die-casting.The main product lines include level switches, level transmitters, flow switches, and other sensors.

- Level transmitters are solutions that continuously measure liquid levels, ensuring process stability. These products convert tank storage levels from 0-100% into instrumentation signals of DC4-20mA or 1-5V. The product range includes various measurement methods such as pressure, radar, and capacitance type. Specifically, the capacitance type utilizes the change in capacitance formed between a probe and the tank wall as a contact sensor technology.Level transmitters are solutions that continuously measure liquid levels, ensuring process stability.
