All-In-One Sensor Technology Developed for the Most Rugged Aqueous, Oil & Hydrocarbon Based Applications


  • Trouble-Free Output, No Moving Parts - solid-state open collector, sinking or sourcing, wet or dry signal.
  • Compact Construction - fits in small spaces, ideal for mobile applications.
  • Wash-Down & Dust Ingress Protection - IP6K9K direct-spray rating for outdoor use in harsh environments.
  • Low-Intrusive Design - minimal internal exposure to sensing element.

The ULS-100 Universal Level Sensor’s sealed construction meets the IP6k9k rating for high-pressure wash-downs. It covers a wide temperature range of -40°F to +185°F (-40°C to +85°C) and a high-pressure range of 300 PSIG (20 BAR) to meet the most extreme conditions. Shock and vibration resistance makes the Universal Level Sensor the one choice for mobile applications.

The sensing element is made of reinforced a PBT/ PC blend, and it features a flush face design. This advanced material and unique flush surface construction reduce false signals caused by coating and build-up that often affect other sensor types.

The ULS-100 Universal Level Sensor utilises a solid state open collector output for point level sensing with high accuracy and repeatability. Without mechanical moving parts, the sensor lasts much longer than common float-type switches which are prone to wear and can fail over time.

The ULS-100 Universal Level Sensor works with a wide variety of media. It eliminates failure caused by moving parts and works well in high-viscous, high-pressure, humid, and reflective applications. It does not rely on specific gravity or conductivity. It is simplifying product selection and reducing inventory with ONE common sensor type to replace them all.

Features & Benefits:

  • Compact – the level sensors feature a small footprint and less intrusive flush sensing element for maximum flexibility.
  • Reliable – accurate and repeatable point-level detection using advanced sensing technology with electronic solid state switching.
  • Durable – universal level can withstand harsh conditions and outdoor environments with IP6K9K rating, wide temperature range and high pressure capabilities.
  • Versatile – reduces inventory and simplifies product selection by replacing several different sensor types with one universal unit for aqeuous, oil and hydrocarbon based media.
  • Approvals - CE and RoHS.

Technical Specifications:

  • Configuration Options – including Wet or Dry, Sinking or Sourcing, Time Display on Rising or Falling and High or Low Dielectric.
  • Physical – 1/2"-14 NPT mounting, Less than 3" overall length, 316L Stainless Steel housing and PBT/PC blend sensing element.
  • Environmental – up to 300 PSIG, from -40°C to +85°C and sealed to IP6K9K ingress protection..
  • Electrical – 9 to 32 VDC supply, 3-Pin Deutsch Connector, 15 mA Max. Current Consumption (No Load) and Open Collector Output (30 mA Max).

Example Applications:

  • Excavators, Earth Movers, Backhoe
  • Harvesters, Sprayers, Planters
  • Buses, Fire Trucks, Ambulances, Refuse Trucks
  • Mining, Military Vehicles, Forestry
  • Power Generation, Renewable Energy
  • Coolant, Hydraulics, Engine Oil
  • Braker, Power Steering, Transmission Fluids
