HNL40-A Rotary Paddle Level SwitchFor powders, granules, and bulk solids. A rotating paddle stops when material covers it — that triggers the switch. Simple. Mechanical. Reliable.
-
HNL10-A Float Level SwitchCompact float switch for liquid level control and alarm. Magnetic reed switch inside a sealed tube – float rises and falls with liquid level, magnet
-
One device. Two measurements. Liquid level switch + temperature sensor in a single housing. Mounts through one tank opening. Saves space, saves installation time. Level output:
-
Continuous level measurement. 4-20mA analog output tells you exactly where the liquid level is – not just “high” or “low”. Hall-effect magnetic sensor inside. External float rises
-
HNL20-B Level + Temperature Sensor – Multi-OutputContinuous level and temperature measurement in one unit. LED digital display shows values at a glance. Up to 4 switch outputs + 2
-
HNL50-A RF Admittance Level SwitchElectronic level switch for liquids, slurries, powders, and solids. No moving parts. No mechanical wear. Probe senses material contact via
-
HNL60-A Capacitive Level Switch – Smart Frequency ScanningCompact capacitive level switch for liquids, pastes, and granular media. Smart frequency scanning technology adapts to
-
HNL70-A Submersible Level SensorDrop it in. Measure liquid level. Diffused silicon or ceramic piezoresistive sensor inside. Measures hydrostatic pressure — level = pressure ×
-
HNL80-A Magnetostrictive Displacement SensorBuilt-in cylinder position sensor for hydraulic systems. Measures piston position and velocity simultaneously. Non-contact — no wear.
-
HNL100-A Ultrasonic Level SensorNon-contact level measurement. Mount it above the tank — no contact with media. No corrosion. No clogging. No cleaning. Range: up to 40m. Accuracy:
-
HNL110-A Radar Level GaugeNon-contact level measurement for liquids, slurries, and solids. 26GHz or 80GHz electromagnetic pulse. Unaffected by dust, steam, foam, or temperature
-
HNL120-A Tuning Fork Level SwitchLiquid. Slurry. Powder. Granules. One switch measures them all. Piezoelectric crystals drive the fork to vibrate at its natural frequency. Contact
Rotating paddle level switches are basically a spring loaded, eccentricaly driven rotating vanes (or blades) which rotate at one revolution per minute, using an ac synchronous motor. When no...
Rotating paddle level switches are sensors with an electrical contact output at a specific powder or bulk level. Applications include mining, silos, hoppers, food & beverage, and grain silos. The...
The rotary paddle type level switch is driven by a micro motor and the drive shaft is connected to the clutch. When the material is not in contact, the motor...
The principle of rotary paddle level switches is based on an electric motor that turns at a low speed, via a transmission and a shaft equipped with one or more paddles. This type of switch is used in...
Depending on the requirements the rotary paddle level sensors are used as a full, demand or empty detector in storage silos or process vessels and is suitable for use in almost all solids. With their...
Rotary paddle level switch – SITRANS LPS200 Rugged, ready, and precise Featuring state-of-the-art safety technology and multiple paddle options, the SITRANS LPS200 is as reliable as it is...
