Geometry
Actual case diameter and tolerance, clamping zone, body length, core length, thread, datum, attachment and connector envelope. Nominal Ø19 mm and 3/4 inch (19.05 mm) are different.
MODEL-BY-MODEL ENGINEERING
A matching diameter
is the start of a replacement review.
Send the full part number, suffix, drawing and electrical specification. LVDT Precision Metrology evaluates a proposed LVP configuration against the installation; listed brands are independent comparison references.

| Original reference | Review route | Critical check |
|---|---|---|
| Macro Sensors HSD 750; Schaevitz DC-EC; HBM WA with amplifier / bridge-interface review | LVP-DC · DC conditioned ↗ | Confirm 12–24 V supply variant, output loading and cable length. |
| Solartron AX / DP; Macro Sensors GHSA / GHSDR; Mahr, Marposs and Tesa probe configurations | LVP-PRB · AC / conditioned variants ↗ | Request repeatability at a defined contact force, approach direction and test method. |
| Macro Sensors CD 375 / MD 375; Schaevitz MHR / XS-B; G.L. Collins miniature configurations | LVP-MIN · Passive AC ↗ | Specify maximum case length, rod attachment and moving mass. |
| Macro Sensors HSTA / HSTAR; Honeywell / Kavlico; turbine feedback configurations | LVP-HT · Passive AC ↗ | Provide continuous and peak temperatures, dwell time and thermal cycling; specify a temperature-qualified metal mounting arrangement. |
| Macro Sensors LPC-2100 / LVC-4000; Schaevitz ATA-2001 / MP2000 configurations | LVP-AMP · Signal conditioning ↗ | Match excitation amplitude, frequency, sensitivity, topology and cable load. |
HSTA / HSTAR 750 are AC-operated families. HBM WA configurations include inductive bridge interfaces; HSD supply requirements must be checked by exact model. Solartron Orbit digital probes and analogue half-bridge probes require their own interface review. Neither is a generic direct RS485 or DC substitute.
Four checks decide whether a candidate can fit.
Electrical chain
Excitation amplitude/frequency, sensitivity, phase, topology, supply, load, scaling, pinout and any digital protocol. A matching connector shell does not prove pin compatibility. Core and coil must be reviewed as a matched assembly; do not assume an existing core can be reused.
Mechanical duty
Working range, pre-travel, overtravel, rod guidance, side loads, spring force, tip thread and expected cycle duty.
Environment & acceptance
Temperature, medium, pressure, ingress, cable/connector seals, vibration and required qualification evidence. Agree acceptance criteria before release.
Send the evidence that makes comparison useful.
Include the full original data sheet, installation drawing, nameplate details, required output and controller model. Tell us which dimensions are fixed and which can change.
Original names and trademarks identify the customer’s installed equipment. There is no claimed affiliation, authorization or pre-approved interchangeability. Prices, availability and delivery are confirmed in the quotation.
