The LD320 series has been replaced by the new and improved LD320A series. Many ranges are in stock, available for immediate shipment.

The LD320 Series displacement sensors have a stainless steel body with improved IP67-rated sealing, coupled with new polymer guides with rigid carriers. These transducers are accurate and reliable, especially in wet and corrosive conditions. An unusually large bore-to-core clearance is maintained throughout the range, even on transducers fitted with on-board signal conditioning. This makes installation easier and helps prevent misalignment.

Regarding LD320-100 is there a spec. for the number of turns or transformation ratio at full scale? Empirically I measured 2.132Vrms when my excitation signal is 3Vrms at 5kHz. But is this spec indicated anywhere?

Asked by: Amr1
There is no documentation indicating this specification. Please send your question to email We would then be able to research your question and respond to you directly with an answer.

What is the resolution?

Asked by: Jackie123
Jackie, We don&rsquo;t spec resolution for this transducer. It is dependent on the electronics that you are using to read the output, for example a digital display that reads to three decimal places. Feel free to contact us if you have any further questions!

One end clearly has a male M6 thread. What is on the other end? Looks like a rounded off square boss. Is there a thread?

Asked by: Elliot
The end of sensor where the cable exits the unit has a threaded plug that can be removed and replaced with a rod end from the LD-UJOINT-KIT. The thread at that end is a M6 female thread.
