The TK-YB Static Pressure and TK-HB Air-Guided Liquid Level Transmitters provide continuous liquid level measurement for industrial and municipal applications. TK-YB measures level through hydrostatic pressure. TK-HB transfers the liquid pressure through an air guide pipe, reducing direct contact between the sensor and the medium and making it suitable for hot, viscous, oily, slurry or corrosive liquids.
- Municipal water supply, drainage, water and wastewater treatment.
- Reservoirs, rivers, marine services, oil tanks and water towers.
- Petroleum, chemical, electric power, coal and metallurgy equipment.
- Level measurement for hot, viscous, oily, slurry or sulfuric acid media.
- Sites requiring IP68 protection and hazardous-area certification.
- Two measurement structures: Select hydrostatic or air-guided construction according to the medium and installation.
- Reduced media exposure: TK-HB transfers liquid pressure through an air guide pipe where direct sensor contact is undesirable.
- Continuous measurement: Suitable for tanks, wells, rivers and industrial vessels.
- Flexible installation: TK-YB supports frame or plate installation; TK-HB supports frame installation or a customer-specified flange.
- Selectable output and communication: 4-20 mA two-wire analog output and HART protocol options.
