LST Series Level Transmitter
The stainless steel level transmitter is engineered to provide continuous and reliable liquid level measurement. With selectable output signals of either 0–5 VDC or 4–20 mA, this transmitter utilizes magnetic reed switches integrated with a resistor network to generate precise, proportional output corresponding directly to the float’s position.
Designed for flexibility, the transmitter supports current or voltage outputs, and includes a four-wire low-level alarm option. It can be externally installed via a 2" NPT connection or flange, providing ease of installation and adaptability. Featuring an optional LCD display for clear and convenient monitoring, the sensor operates reliably within a broad temperature range of -30℃ to 125℃, and withstands working pressures from 1.5 MPa to 4.0 MPa.
- Excellent corrosion resistance ensures longevity and consistent performance
- Supports remote liquid level display and control functionality
- Optional LCD display available for convenient monitoring
- Wide operating temperature range for versatile industrial use
The level transmitter is suitable for demanding applications involving sanitary, toxic, corrosive, or explosive media. Industries extensively utilizing this transmitter include petrochemicals, medical equipment manufacturing, research laboratories, food and beverage production, chemical storage tanks, and other specialized fields requiring precise and safe liquid-level monitoring.
