Closed-Tank Level Transmitter

Model No: KCPT-LT-TX

Closed-Tank Level Transmitters are designed for continuous liquid-level measurement in pressurised and sealed vessels using differential pressure measurement.

The transmitter measures the pressure difference between the bottom and top of the vessel, automatically compensating for tank pressure to provide an accurate level signal. Depending on the installation, the transmitter can be connected through direct impulse lines or remote diaphragm seals with capillaries.

Available with 4–20 mA output, HART or RS485 Modbus RTU communication, local LCD indication, flameproof enclosure, and SS316L, Hastelloy C, Tantalum or PTFE-coated diaphragm options, the transmitter is suitable for demanding process applications involving pressure, temperature or corrosive media.
