Many of Delta’s customers have successfully used the linear position transducers with SSI output listed below.
The RMCs accept both Binary and Gray Code options, but Delta recommends Binary coded transducers because it is easier to monitor the signals using an oscilloscope scope, and Gray code has no benefits in these situations.
# of Bits
Delta typically recommends 24 bits. The RMCs can handle up to 32 bits, but going beyond 24 can cause the Actual Position to lose resolution. This occurs because the Actual Resolution is stored as a 32 bit floating point number which is limited to 24 bits of precision.
Delta typically recommends the highest available resolution. Even if the machine need not be that accurate, higher resolution improves the functionality of the Differential Gain or Double Differential Gain. In rare cases, very long lengths and high resolution can cause the data to exceed 24 bits (see discussion above), so the resolution may need to be reduced.
R-series: Magnetrostrictive sensor with SSI output.
Make sure to specify the synchronized 02 option, as described on page 14 of the pdf below. If using the Advanced options, it is any of the synchronized options.
Most customer use the No Filter option.
E-series: The economical line. The SSI option works with the RMC, but the resolution isn’t as high as the R-series.
BTL5, BTL7: Magnetrostrictive sensors with SSI output. Make sure to specify the synchronized option B, as described in the Balluff transducer catalog.
BML series: This is an absolute SSI linear magnetic tape sensor with high resolution. Make sure to specify SSI.
AMETEK Gemco 953S
Magnetrostrictive sensors with SSI output. Make sure to specify the Synchronous Position Update option.
