How it works

 

 

A waveguide wire runs inside the stainless steel probe. A magnetic float rides on the outside of the probe. When the float moves, it creates a strain pulse that travels back to the sensor head. The electronics measure the pulse return time - that time equals position.

 

HNL30-A prin

 

What that means for your tank:

  • ±0.1mm accuracy - not ±5mm, not ±10mm
  • No moving parts inside the probe - no mechanical wear
  • No calibration - no drift, no re-zeroing
  • 25-2500mm range - one sensor covers most tank sizes

 

 

 

Where to use it

 
HNL30 24

Water treatment tanks
Clean water and wastewater level monitoring. SUS304 wetted parts handle mild corrosive conditions. 4-20mA output to SCADA or PLC.

Hydraulic oil reservoirs
Long-range level detection up to 2500mm. High resolution detects oil consumption trends. RS485 output for digital communication to DCS.

Industrial storage tanks
General chemical and solvent level monitoring. SUS316L option for improved corrosion resistance. No calibration - install and forget.

Cooling water towers
Level monitoring in open and closed-loop cooling systems. IP67 rated for outdoor installation. Thread or flange mounting options.

Food processing
Sanitary level monitoring in food-grade tanks. Stainless steel wetted parts meet hygiene requirements. RS485 or 4-20mA output to control system.

HNL30-A Magnetostrictive Level Gauge Parameters

Specific Parameters

Value / Description

Measurement Principle

The HNL30-A magnetostrictive level gauge is a high-precision continuous level measurement instrument based on the magnetostrictive effect. It calculates the liquid level height by detecting the propagation time of the magnetic coupling signal. It features high accuracy, high stability, and non-contact measurement, and is widely used in continuous level/interface monitoring in industrial processes. It supports the measurement of various media such as conductive/non-conductive, viscous/corrosive media.
