Description

The PR-PT604-H is an economical, fully sealed submersible level transducer designed for permanent installation in liquid media. Its core utilizes a high-stability, German-imported piezoresistive pressure sensor coupled with a precision signal conditioning circuit, all housed within a durable stainless steel body. This integrated construction outputs a standard 4-20mA signal, enabling straightforward connection to control systems without the need for additional signal converters.

Engineered for harsh environments, the sensor features surge protection, RFI/EMI resistance, and is rated for 1.5x standard overload and 5x burst pressure. Its compact size, light weight, and 3-meter integrated PE cable make it suitable for deployment in water tanks, fuel storage, drainage systems, hydrology monitoring, and various industrial process control applications where reliable liquid level data is critical.

Key Features

High-value build with a fully sealed, IP68 submersible stainless steel housing.
Stable 4-20mA two-wire current output ensures signal integrity in electrically noisy industrial settings.
Wide operating temperature range and excellent resistance to shock, vibration, and media erosion.

Frequently Asked Questions

What is the wiring configuration for the 4-20mA output?

This is a two-wire 4-20mA loop-powered sensor. Connect the red wire to your positive DC power supply (12-30V) and the black wire to your data acquisition input or PLC analog input module. The same two wires carry both power and the proportional current signal. Ensure your receiver is configured for a current loop input.

Can this sensor be used with liquids other than water?

Yes, the stainless steel housing and PE cable are compatible with many non-corrosive, non-clogging liquids such as fuels, oils, and certain chemicals. However, for aggressive media, verify chemical compatibility with the housing and cable material. The sensor measures hydrostatic pressure, so the density of the liquid will affect the level reading and may require calibration scaling.

How do I mount and install the PR-PT604-H sensor?

For submersible level measurement, lower the sensor into the tank or well until the sensing port is at the desired zero-reference depth. The sensor can be suspended by its cable or mounted via a threaded fitting (check datasheet for specific thread size). Ensure the cable gland is properly sealed. The sensor must be fully submerged for accurate measurement, and the vent hole in the cable must remain above the liquid level and be exposed to atmospheric pressure.

What is the difference between accuracy ratings of 0.5% FS and 1% FS?

The sensor typically achieves ±0.5% Full Scale accuracy under standard conditions. The 1% FS rating is a more conservative, guaranteed specification. Accuracy can be influenced by temperature, installation, and media properties. For critical applications, refer to the detailed datasheet for temperature coefficients and non-linearity specifications to calculate total measurement uncertainty.
