ST-600 Float Type Level Transmitter

Type & Model Float Type Level Transmitter

Principle A circuit, in which the resistance and the reed s/w is serially connected in intervals of 1-2cm, is installed inside the pipe. When the float, equipped with the magnet, moves up and down the pipe by buoyancy, the reed s/w is cut short, and the total resistance value changes until the cutting is summed. The resistance value that had changed based on the level of the fluid is transformed into an electric current signal DC 4-20mA, and put out. This is the most general level control and instruction device. - Separately sold Control Unit

SFP Pneumatic Type Level Switch

Type & Model Pneumatic Type Level Switch

Principle A pipe (with its lower part opened) is cut in the length of the electric contact's location, and sealed with a sensor, and then installed; the level of the fluid rises, increasing the pressure in side the pipe, and this water pressure pushes up the expanded diaphragm in the lower sensor, operating the Micro S/W connected to the upper part, for output. It is mostly used for open type fluid tanks that do not have pressure. When a H/L electric contact is required, two sensors are used. The on-off operation static head difference is 20mm. This model also is a unique product of our company.
