LVP-HT / Passive AC
Passive AC displacement transducer configurations with remote signal conditioning for hot valves, hydraulic test systems and harsh-environment development. Review temperature and pressure together.
Requests to 220°C, optional 350°C or 250 bar are configuration targets, not simultaneous certified ratings.
Steam-turbine valve development, hot materials tests, hydraulic pressure systems and aerospace actuator research.

Wire count and cable colour do not identify a universal pinout. Use the released sensor and conditioner drawings.
+V → sensor
Common ↔ PLC reference
Signal → voltage / current input
Separate supply and output; check output load. Colours such as red, black and green are examples only.
Supply + / supply return
Signal + / signal return
Confirm isolation and reference
A fourth wire may have another purpose. A two-wire 4–20 mA loop needs its own wiring diagram.
2 primary excitation leads
4-wire: opposed secondaries internally joined
5-wire: centre tap; 6-wire: separate coils
Match phase, amplitude, frequency and topology to the conditioner. Pair with LVP-AMP after review.
3-wire may be an inductive half-bridge
RS485: power, A/B and reference per model
Orbit requires its network interface
Half-bridge, analogue AC and digital networks are distinct interfaces.
MECHANICAL SELECTION
Separate the moving core from the coil body. External guidance must maintain clearance; the electromagnetic sensing element has no sliding electrical contact.
A guided assembly simplifies linkage. Review side load, rod alignment, bearings and usable travel before integrating.
A contact tip follows the measured surface. Review tip force, pre-travel, overtravel and contact wear.
Concept schematics. Non-contact induction does not make bearings, springs or contact tips wear-free.
CONFIGURATION RELEASE
Agree bipolar range, null, sensitivity and residual error against a reference displacement stage. State whether error is % of full range or reading.
Define approach direction, probe force, electronics, filtering, temperature and sample method. Resolution alone does not describe repeatability.
Check temperature drift, warm-up and mounting stress. Confirm pressure, medium, cable and sealing conditions for the complete assembly.
A proposed review plan, not a claim that a specific LVP model has completed qualification.

Send the working range, mechanical arrangement and electrical interface. Add the original model when reviewing a replacement.
[email protected] ↗No. The listed values define the selection request envelope. The quote and released drawing identify the exact range, body size, electrical interface and acceptance conditions.
Yes. Include your installation envelope and required file format in the RFQ. Configuration-specific documentation follows engineering review; an illustration on this page is not a release drawing.
Review the sensor manufacturer’s mounting recommendations. Magnetic materials and excessive clamping force can affect some designs. Specify the clamp material, bore tolerance and torque rather than assuming every metal clamp is unsuitable.
Provide the configuration, quantity and delivery destination. Engineering will confirm the quotation, available documentation and schedule for that request.
