Custom Submersible Level Sensors

Custom submersible level sensors offer cost and competitive advantages

First Sensor offers diverse possibilities to customise its broad range of Sensortechnics submersible level sensors. These include special pressure ranges, calibrations and output signals as well as specific materials for the housing, sensing element, O-ring seals and sensor cable. The fast and cost-effective sensor modifications from First Sensor allow OEM device manufacturers to shorten their development time and achieve competitive advantages through fast innovations to the market.

First Sensors hydrostatic liquid level sensors are optionally based on long term stable stainless steel or ceramic pressure sensor elements with measuring ranges from 50 mbar (0.5 mH₂O). The submersible level sensors ensure excellent media compatibility for many corrosive and aggressive liquids. Flush mount versions are suitable for viscous media. Optional coatings (e.g. Parylene) achieve additional protection for particularly rough environments. The sensor housings can be constructed very rugged or slim with an outside diameter of only 21.8 mm for probe tubes or tanks with small apertures. The housing material consist of stainless steel or PPS plastic, on request also titanium is possible. All common current and voltage output signals are available such as e.g. 4...20 mA, 0…20 mA, 0...10 V, 1...6 V. Optionally First Sensor offers digital interfaces (RS-232, RS-485 etc.), temperature outputs as well as sensors with HART protocol and ATEX certification. 3 V supply versions are ideal for battery powered applications.

Important features of the custom submersible liquid level sensors:

• Stainless steel or ceramic pressure sensor elements
• Measuring ranges from 50 mbar (0.5 mH₂O)
• Current or voltage output signals, digital interfaces
• Stainless steel or PPS plastic sensor housings

Custom Sensortechnics submersible level sensors are ideally suitable for level control of tanks and liquid supplies as well as level measurement in rivers, wells, water reservoirs and waste waters.
