Submersible Liquid Level Transmitter

Model: PT124B-220

Description:

The PT124B-220 Submersible Liquid Level Transmitter is a high-precision hydrostatic level sensor designed for continuous liquid level measurement in water, wastewater, and industrial fluids.

Built using a diffused silicon piezoresistive pressure sensor, it delivers accurate and stable readings by converting liquid pressure into a standard electrical signal for monitoring and control systems.

With its IP68 fully sealed design, the transmitter can be directly submerged in tanks, wells, reservoirs, and pipelines, making it ideal for long-term, maintenance-free operation.

Features:

  • High-Accuracy Hydrostatic Measurement: Uses advanced piezoresistive sensing technology for precise liquid level detection.
  • Fully Submersible (IP68 Rated): Designed for continuous immersion without water ingress or performance degradation.
  • Wide Measurement Range (1m–50m): Suitable for shallow tanks to deep wells and reservoirs.
  • Multiple Output Signals: Supports 4–20mA, voltage outputs, and integration with PLC/SCADA systems.
  • Temperature Compensation: Ensures stable readings even in fluctuating environmental conditions.
  • Long-Term Stability: Low drift and high repeatability for reliable industrial performance.

Application:

The PT124B-220 is widely used in:

Water & Wastewater

  • Storage tanks
  • Sewage treatment plants
  • Reservoir level monitoring

Industrial & Process Control

  • Hydraulic systems
  • Cooling water systems
  • Industrial tanks

Environmental & Municipal Systems

  • Groundwater monitoring
  • Rivers and lakes
  • City water supply systems

Other Applications

  • Petroleum storage
  • Metallurgy processes
  • Agricultural irrigation systems
