Magnetostrictive level measurement MS

Magnetostrictive level measurement MS

Overview
High accuracy, high resolution float level sensor that operates based on the Wiedemann effect. Intrinsically safe model available (TIIS Exia ⅡC T5)
Features
High accuracy (±1 mm/±0.1%F.S.) and high resolution
Applications
Applications that require high accuracy such as chemical in pharmaceutical plants, drink blending tanks.

Hydrostatic Level Measurement PLD (removable)

Hydrostatic Level Measurement PLD (removable)

Overview
Suspended or sunk in a liquid, the sensor receives liquid pressure with the diaphragm at its end. The incorporated semiconductor pressure sensor continuously converts the pressure to electric signals.
Features
Operational right after being suspended or placed in water. Without moving parts and easy to operate.
Applications
Wastewater treatment facilities, manhole pumping stations, water reservoirs, deep wells, dams, rivers, and silos.

Hydrostatic Level Measurement PLD4000 (digital correction, removable)

Hydrostatic Level Measurement PLD4000 (digital correction, removable)

Overview
2 wire sensor with high lightning resistance, improved stability and easier maintenance.
Features
Operational right after being suspended or placed in water. Simple design without moving parts. Replaceable detector.
Applications
Water intake stations of hydraulic power plant

Air bubbler system LA

Air bubbler system LA

Overview
Controller sends air to the sensor placed in liquid, and measures the back pressure with a pressure sensor to give continuous level indication.
Features
Simple design without moving parts. Operational even in corrosive liquids.
Applications
Level measurement of sludge, highly viscous or corrosive liquids and liquids with suspended solids.

Pressure Transmitter PKD120/130

Pressure Transmitter PKD120/130

Overview
Continuous level sensor whose diaphragm at the center of the flange receives liquid pressure, and semiconductor pressure sensor converts the pressure to electric signals.
Features
Extremely simple and low cost.
Applications
Pure water, wastewater or chemicals.
