A magnetostrictive level transmitter is a contact level instrument that measures liquid level by timing a pulse between the transmitter head and a magnetic float. It is also known as a magnetostrictive level sensor or magnetostrictive level gauge. With millimeter-level accuracy, it is one of the most precise technologies for tank gauging. The CZ80 series from Silver Automation Instruments measures level, oil-water interface and up to 5 temperature points from one probe, with ±0.5 mm accuracy.
Full specifications, dimensions and the ordering code are in the data sheet.
Inside the stainless steel probe runs a special wire called a waveguide. Around the probe sits a float with permanent magnets in it, and that float simply rides on the liquid surface.
Every measurement starts with a short current pulse sent down the waveguide by the electronics. As the pulse passes the float, its magnetic field meets the field of the float magnets. This twists the wire slightly at that exact spot and sends a small strain pulse back up to the head, where a sensing coil picks it up.
In short, a magnetostrictive level transmitter measures level by timing that return pulse. The pulse always travels at the same speed, so the delay converts directly into float position, which is the liquid level.
For interface measurement, a second float is added. It is heavier than the top liquid but lighter than the bottom one, so it settles at the boundary, for example where oil sits on water.
Which model fits depends on your tank. The CZ80 magnetostrictive level sensor comes in six versions, from standard storage tanks to high-pressure vessels, deep tanks and retrofits on magnetic level gauges already in service.
| Model | Type | Measures | Probe | Best for |
|---|---|---|---|---|
| CZ-81 | Single parameter | Level or interface | Rigid rod | Small and medium tanks, pools, water tanks |
| CZ-82 | Multi-parameter | Level, interface, 1 to 5 point temperature | Rigid rod | Storage tanks needing inventory and temperature data |
| CZ-83 | High pressure | Level, interface, 1 to 5 point temperature | Rigid rod, titanium alloy, custom float | High-pressure vessels up to 10 MPa |
| CZ-84 | High temperature | Level, interface, 1 to 5 point temperature | Rigid rod, stainless steel, custom float | Hot process media |
| CZ-85 | Flexible cable | RS-485: level, interface, multi-point temperature. 4-20 mA: level or interface | Flexible cable up to 20 m | Deep tanks, tank farms, underground fuel tanks |
| CZ-86 | Strap-on | Level or interface | Mounted outside a magnetic level gauge | Adding a remote 4-20 mA or RS-485 signal to an existing magnetic level indicator |
Magnetostrictive, radar and ultrasonic level transmitters all give continuous level, but they suit different jobs. Pick magnetostrictive for millimeter accuracy and interface measurement in clean liquids. Pick a radar level transmitter when the medium is sticky, crystallizes or carries solids.
| Magnetostrictive | Radar | Ultrasonic | |
|---|---|---|---|
| Measuring method | Float on probe, pulse timing | Microwave, non-contact | Sound wave, non-contact |
| Typical accuracy | ±0.5 mm | Millimeter range | About 0.2% of span |
| Interface measurement | Yes, with second float | Limited (guided wave only) | No |
| Multi-point temperature | Yes, 1 to 5 points | No | No |
| Contact with medium | Yes | No | No |
| Best for | Fuel and chemical inventory, oil-water interface | Sticky, dirty or high-temperature media | Water and wastewater, open tanks |
