Vibration TransmittersMeasuring range / features
Requested displacement 0–10 / 20 mm peak-to-peak, or heavy-duty low-frequency velocity. Confirm operating frequency and maximum shock independently.
VTX-SCR / HARSH DUTY REVIEW
Mining screen & harsh-duty vibration sensors
Measure the process motion before judging the machine.
Specify vibration measurement sensors for screens, crushers and mills, or review vibration monitoring for oil and gas machines. Measurement range, low-frequency response and installation conditions come first.
BEFORE YOU SPECIFY VTX-SCR
A screen vibrates by design. Monitor stroke, frequency, symmetry and change from baseline; do not apply a normal motor severity threshold to the screen box.
An Ex-style housing does not establish ATEX / IECEx approval. Supply zone, gas or dust group, temperature class and certificate requirements before any hazardous-area recommendation.
SIGNAL ARCHITECTURE / VTX-SCR
From the measurement point to your control interface.
Plan the power and data path as one installation. The receiving input, cable or network and selected model determine the final connection.
Power & output
4–20mA output with overload / saturation behavior to confirm; armored cable routing and plant grounding review.
Mounting & wiring
Rigid, prepared machine pad and protected armored cable. Mount position, machine movement and cable fatigue need a site drawing.
Machine / process fit
Mining vibrating screens, crushers and mills; separate certification-led review for oil and gas rotating machinery.
Configuration targets for quotation. Final ratings, released drawings, available reports and delivery are confirmed for the selected model.
MODEL / DETECTOR / BAND / INTERFACE
Build a VTX-SCR request configuration.
Select a model request profile and the interfaces to review. The written quotation establishes the final ordering code and released ratings.
VTX-SCR
4–20mA displacement [mm peak-to-peak]
Specify stroke, frequency, shock and cable restraint drawing.
Carry this configuration to RFQ →Request evaluation units →| Profile | Measurement | Band / timing | Interface | Confirm in quotation |
|---|---|---|---|---|
| VTX-SCR Screen stroke / heavy-duty motion | 0–10 / 20 mm peak-to-peak requested | Operating frequency and shock to confirm | 4–20mA + protected cable | Specify stroke, frequency, shock and cable restraint drawing. |
| VTX-420-EX Hazardous-area configuration review | Velocity / acceleration by configuration | Machine-specific band to confirm | 1/2 NPT / M20 conduit request | Certification availability, full marking and loop parameters require review. |
Size the screen stroke and the overload separately.
Screen stroke → velocity RMS
Use this sine-motion example to check whether a normal motor transmitter range fits intentional screen motion.
900 RPM and 10 mm stroke give about 333.2 mm/s RMS under sinusoidal motion. Actual waveform, overload survival, passband and output saturation require the selected sensor documentation.
Stroke and operating frequency
Provide normal and maximum peak-to-peak stroke, machine speed, axis and impact duty. Quote the displacement band, overload limit and saturation behavior together.
Moving cable restraint
Show the sensor location, restrained lead, moving loop, bend radius and transition to stationary cable. Include guarding against flying material and the maintenance removal path.
VTX-420-EX area review
Specify gas/dust area, temperature class, ambient range, certificate requirements and 1/2 NPT or M20×1.5 conduit request. For intrinsic safety, include the barrier entity parameters and cable capacitance/inductance.
Review the compliance document list →HOUSING / CONNECTION / INSTALLATION
Start with stroke and speed, then design the mounting.
Low-frequency housing examples help plan the installation. Required displacement span, shock survival and overload behavior need separate configuration evidence.
Cable entry and strain relief
Review movement, impact exposure and routing. Request the required cable protection rather than infer it from a housing photo.
A rigid mounting interface
Check surface preparation, stiffness, adhesive qualification or a machined mounting face for the measurement point.
Matched stud engagement
Specify both mating threads, engagement depth and installation torque in the controlled drawing.
Take the VTX-SCR configuration to purchasing.

RANGE / THREAD / CONNECTOR REVIEW
Metric or imperial.
Verify the complete interface.
| Interface | Metric request | Imperial request | Check before ordering |
|---|---|---|---|
| Velocity units | 0–10 / 20 / 25 / 25.4 / 50 mm/s RMS | 0–0.5 / 1.0 / 2.0 in/s = 12.7 / 25.4 / 50.8 mm/s | Confirm RMS, Peak or derived Peak and the original full scale |
| Mounting stud | M8 × 1.25 or M6 | 1/4–28 UNF | Pitch, thread depth, gender, seating face and torque |
| Connection | M12 4-pin | 2-pin MIL-C-5015 | Exact pinout and mating connector; not implied by connector shape |
| Other interfaces | Integral cable / protected cable | 1/2 NPT conduit entry where applicable | A conduit thread is not interchangeable with a mounting stud |
For screen displacement, specify mm peak-to-peak and operating frequency; velocity units do not define stroke.
INSTALLATION KIT / FEWER LOOSE ENDS
The mounting pad is
part of the signal chain.
A suitable pad, correctly wired cable and matched readout can simplify a plant rollout. Choose only the accessories your output needs in the form below.
Glue-on pads require a rigid, prepared mounting surface and qualified adhesive. Thin motor fins, fan guards and flexible covers are unsuitable default measurement points.
01 Prepared mounting pad & matched stud
02 PUR / armored cable or matched wireless gateway
03 Local display / relay monitor where applicable
04 Handheld meter for comparable spot-check readings
All kit options quoted separately. No preselected purchase obligation.What to send for a VTX-SCR review
Can you review an existing sensor?
IMI 645B and Hansford references require full-range and passband review. An original mil-scale displacement transmitter is not an automatic match for a 10–20 mm screen stroke. These are identification references only. Send the full suffix, datasheet and wiring drawing; there is no automatic drop-in or authorization claim.
What about calibration, sealing and area certificates?
List the required calibration method and traceability, enclosure rating, local conditions and certification scope. Only configuration-specific documents establish suitability; a housing style or series name is not evidence.
How do I plan a 10, 50 or 200+ point rollout?
Share an asset list, measurement points per asset, control architecture, cable lengths and destination. Request a pilot configuration before a larger rollout. Pricing and lead time follow the reviewed bill of materials.
Quote the sensor and installation kit line by line.
| Request code | Item | Quantity basis | Fit and environment review |
|---|---|---|---|
| VTX-ACC-PAD | Prepared glue-on pad / fin-mount adapter review | per mounting point | Rigid load path, actual fin geometry, adhesive, cure, temperature and installed response. |
| VTX-ACC-CBL | 5 m PUR / armored cable request | per cable assembly | Length, sheath, connector coding, pinout, cable restraint and temperature. |
| VTX-DIN | Local display and relay monitor | per monitored channel | Loop powering, engineering units, relay ratings and reset. |
