Description

The OULD PT-928 Submersible Pressure Level Transmitter operates on the principle of measuring hydrostatic pressure, which is directly proportional to the height of the liquid column above the sensor. It utilizes a high-performance diffused silicon sensor core with integrated signal conditioning, providing a stable and temperature-compensated 4-20mA analog output signal.

Engineered for continuous submersion, the transmitter features a breathable cable to prevent gauge pressure errors and a protective cover over the pressure inlet to guard against sediment and debris. Its robust construction and wide supply voltage range (10-36V DC) ensure reliable operation in water treatment, irrigation, chemical processing, and environmental monitoring applications.

Key Features

  • Submersible pressure transmitter with 0-10 meter integral cable.
  • High-accuracy 4-20mA two-wire output with ±0.5% FS precision.
  • Advanced digital temperature compensation and nonlinear correction.
  • Wide operating temperature range from -40°C to +85°C.
  • Protective sediment cover for the pressure inlet port.
  • Breathable cable design to eliminate atmospheric pressure errors.
  • Robust construction for long-term stability in demanding environments.
  • Wide 10-36V DC supply voltage compatibility.

Applications

  • Continuous level monitoring in water storage tanks and reservoirs.
  • Depth measurement in boreholes, wells, and groundwater monitoring.
  • Process tank level control in chemical and pharmaceutical industries.
  • Irrigation system water level management and pump control.
  • Liquid level sensing in wastewater treatment and environmental sumps.

Frequently Asked Questions

What is the power supply requirement for the PT-928 transmitter?

The PT-928 operates on a wide-range 10-36V DC power supply, which is standard for two-wire 4-20mA loop-powered transmitters. The same two wires carry both the power and the output signal, simplifying installation.

How do I install and mount this submersible level sensor?

Installation involves submerging the sensor to the desired depth in the liquid. The transmitter body should be securely fixed, and the integral cable routed out of the tank or well. Ensure the protective sediment cover is clean and unobstructed for accurate pressure reading.

Can the output signal be converted or interfaced with a data logger or Arduino?

Yes. The 4-20mA signal can be converted to a voltage using a precision resistor (e.g., 250Ω for 1-5V) and read by an analog input on a PLC, data logger, or microcontroller with an ADC. Ensure your reading device is compatible with the loop power configuration.

What is the purpose of the 'breathable cable' feature?

The breathable cable prevents a vacuum from forming inside the cable sheath, which could cause a gauge pressure error if the atmospheric reference at the transmitter end becomes disconnected. This ensures the sensor always references ambient atmospheric pressure correctly.
