LVP-DC / DC conditioned
Conditioned displacement feedback for industrial controls, hydraulic presses and valve position measurement. Specify the supply, signal and mechanical interface as one configuration.
A built-in conditioner simplifies integration; loop current and voltage variants have different connection requirements.
Hydraulic press stroke, test-machine displacement and industrial valve feedback.

Check the replacement process ↗LVP-DC / DEFINE THE INTEGRATION
A DC-LVDT request needs an electrical boundary as well as a displacement range. Identify the receiver, supply and signal reference before choosing a housing or ordering a replacement.
Identify whether the PLC channel supplies loop power or expects an active transmitter. Request the supply range, minimum operating voltage, receiving resistance and cable-drop allowance together.
A 4–20 mA label alone does not establish loop compatibility. Do not connect two powered outputs together.
Specify the output at both physical travel endpoints, the null position, receiver impedance and shared or separate returns. State whether a negative rail is available.
A ±10 V signal request does not imply that every transmitter can run from one +24 V rail.
Request the protocol and register map, signed position units, baud rate, addressing, scaling and grounding. Define update time with the required filtering.
RS485 is a physical interface; it does not establish a register map or direct Orbit compatibility.
Technical background for these interface distinctions. Manufacturer references do not establish LVP ratings.

Provide maximum body length, core or rod length, datum-to-null distance, thread, connector clearance and permitted overtravel. Dimension letters differ between original manufacturers. Use the exact released drawing for an installation comparison.

EXCITATION & CONNECTION TOPOLOGY
Use these circuit principles to identify the required sensor and conditioner. Cable colour, shield count and connector shell do not establish a pinout.
The loop supply, sensor and receiving load form one series circuit. Check minimum sensor voltage, receiver burden and maximum cable drop.
Open circuit at full size ↗
Supply, common and conditioned signal are distinct functions. Voltage and active current versions require their corresponding PLC input mode.
Open circuit at full size ↗
This example separates the power and output returns. It does not imply isolation; other four-conductor definitions require the actual drawing.
Open circuit at full size ↗P1/P2 and S1/S2 identify winding functions; they are not physical connector pin positions. Digital RS485 additionally requires supply, reference, polarity, termination and register-map confirmation. Orbit needs its own network interface.

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.
OPERATING CONDITIONS TO SEND WITH THE RFQ
Illustrative requirement checklists for engineering review. Supply your actual operating conditions and acceptance limits.
Provide cylinder working travel, maximum overtravel, linkage geometry, vibration, oil exposure and PLC input. Specify the operating temperature at the sensor and connector.
State valve closed/open datums, required output direction, linkage play and adjustment access. A position indication must be assessed separately from any protective control function.
Give extension/compression travel, required sampling rate, uncertainty target and fixture movement. Separate the transducer displacement from specimen strain and machine compliance.
AGREE THE METHOD BEFORE THE ORDER
Proposed review steps. The quotation and agreed test plan define the actual test points, conditions, tolerances and deliverables.
Confirm supply at the sensor under the intended load, then record the zero and span outputs using the agreed receiver and cable.
Compare indicated displacement with a suitable reference across the agreed working range. Record direction, residuals, return-to-null and the method used for linearity.
Repeat checks after final clamping, warm-up and the defined temperature condition. Agree acceptance limits before the order; no numerical pass threshold is supplied by this guide.
These steps are a planning framework. No measured LVP data or completed qualification is represented.
REQUEST A CONFIGURATION REVIEW
LVP-DC · DC-DC LVDT Position Sensors
Choose the required configuration, then add the mounting envelope, environment and original model. Drawings, compatibility and commercial scope are confirmed with the quotation.
inquiry@lvdtsensor.com ↗No. Loop-powered and separately powered current-output versions use different connections. State the PLC input mode and power arrangement, then request the selected model drawing.
That depends on the electronics variant. Request the actual supply requirements and output compliance; a signal labelled ±10 V does not establish the required power rails.
Send the full original suffix, supply schematic, output endpoints, body/core dimensions and connector mating view. The replacement review must cover the receiver as well as the sensor.
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.
