submersible pressure transmitters, are pressure sensors with a specific design. They are responsible for hydrostatic level measurement in tanks, wells, shafts and boreholes and guarantee unsurpassed leak tightness as well as media resistance.

WIKA defines a pressure transmitter as a pressure sensor with standardised electrical and mechanical interfaces and a standardised output signal.

SITRANS Level Measurement (Siemens)

Siemens SITRANS devices are used to measure liquid, solid, and slurry levels in tanks, silos, and vessels across industries like water, cement, food, and chemicals.

📏 Main Types of SITRANS Level Measurement 1. 🌐 Ultrasonic Level (SITRANS LU Series) 🔹 Examples:

• SITRANS LU150
• SITRANS LU240

🔹 Principle:

• Sends ultrasonic waves → measures echo time

🔹 Features:

• Non-contact
• Easy installation
• Good for liquids and some solids

🔹 Applications:

• Water tanks
• Wastewater plants
• Open channels

2. 📡 Radar Level (SITRANS LR Series) 🔹 Examples:

• SITRANS LR100
• SITRANS LR250

🔹 Principle:

• Microwave radar signals reflect from surface

🔹 Features:

• High accuracy
• Works in dust, vapor, temperature
• Suitable for harsh conditions

🔹 Applications:

• Chemical tanks
• Cement silos
• Fuel storage

3. 🧪 Guided Wave Radar (SITRANS LG Series) 🔹 Example:

• SITRANS LG250

🔹 Principle:

• Radar travels along a probe (rod/cable)

🔹 Features:

• Works in foam, turbulence
• Measures interface (liquid-liquid)

🔹 Applications:

• Oil-water separation
• Chemical industries

4. ⚖️ Capacitance Level (SITRANS LC Series) 🔹 Example:

• SITRANS LC300

🔹 Principle:

• Change in capacitance with level

🔹 Features:

• Simple and cost-effective
• Good for solids and liquids

🔹 Applications:

• Powder, grain, bulk solids

5. ⚙️ Hydrostatic Level (Pressure Type) 🔹 Example:

• SITRANS P

🔹 Principle:

• Measures pressure due to liquid height

🔹 Features:

• Reliable for liquid level
• Works in closed tanks

🔹 Applications:

• Water reservoirs
• Tanks

6. 🚨 Point Level Detection (Switches) 🔹 Examples:

• SITRANS LVS100
• SITRANS LPS200

🔹 Function:

• Detects HIGH / LOW level (not continuous)

🔹 Applications:

• Overflow protection
• Dry run protection

ITRANS LR560 2-wire, 78 GHz FMCW radar level transmitter for
continuous monitoring of solids and liquids to a range of 100 m
(328 ft).

SITRANS LR560 is the first choice and easiest-to-use solids radar transmitter on the market. With a high frequency of W band (78 GHz), 4-degree narrow beam, and short wavelength, it performs reliably on solids material from practically any installation location.

This loop-powered device provides accurate level measurement up to 5.5 m (18') and is the ideal choice for more challenging coating or scaling liquids, including sodium hydroxide, wastewater, resin, wax, liquor, and bleach. An ultrasonic sound wave is pulsed 2 times per second from the base of the transducer.
