7.4: Notes
1.
Primary voltage absolute value and drift is not specified. The LDX-4 uses ratio-
metric techniques to compensate for primary voltage drift.
2.
The way in which the LDX-4 functions means a special configuration must be
used for transducers outside of the standard range. This is selectable by links.
The majority of Omega LVDT transducers are within the standard range. See
section 5.
3.
LDX-4 can drive into a 1 KW load but this offers no advantage. 10-100 KW is
recommended.
4.
Output voltage range can be adjusted as required anywhere within this range
by using a combination of gain and offset, for example. ±10 VDC, ±5 VDC, 0-5
VDC, 0-10 VDC, 4-20 mA.
5.
Current output may be used at the same time as voltage output. Calibration of
voltage and current cannot be individually adjusted.
6.
Protection applies to the product when fully installed according to the user
manual. During installation the top of the enclosure has to be removed for ac-
cess to user adjustments. At this time standard ESD handling precautions for
electronic equipment should be followed.
7.
The LDX-4 complies with the toughest electrical emissions and immunity
regulations. Compliance requires installation according to the user manual.
Compliance does not guarantee performance as the installation environment
may be outside of test specification limits. The flexibility of LDX-4 means it can
be installed in a variety of ways according to user requirements. Simple instal-
lations with short non-screened cables will meet the lesser light-industrial im-
munity regulations. Heavy industrial installations, especially with longer cables,
will need more careful installation with screened cables.
