Configuration

330750	High Temperature Velomitor system
20	2 m integral hardline cable
05	Multiple approvals (CSA, ATEX and IECEx)

Applications

High-temperature velocity measurement on turbines, compressors and other rotating machinery.

Mount the sensing head on surfaces up to 400 C while locating the electronics in a cooler area.

Use for continuous machinery protection and condition-monitoring velocity channels.

Select hazardous-area wiring and approvals to match the installed location.

Installation

Sensor mounting	Use the four-hole sensor-head pattern and dimensions shown in the 330750 drawing.
Cable routing	Maintain the 51 mm minimum bend radius and protect the integral 2 m hardline cable.
Electronics location	Keep the signal-conditioning electronics within the -55 to +121 C limit.
Interconnect wiring	Use the required two-conductor, double-shielded cable and maintain polarity.
Environmental protection	Install the electronics in a protected enclosure and add splash protection where required.

Compatibility

Monitoring input	Compatible Bently Nevada machinery protection or condition-monitoring velocity input
External cable	Two-conductor double-shielded interconnect cable; maximum 305 m
Mating interface	2-pin MIL-C-5015 receptacle
System identity	Do not substitute 330752 without checking integral-cable length and dimensional differences
Approval match	Use the 05 multiple-approval execution only where its entity and installation requirements are met

FAQ

Q1. How can I verify that the quoted product is the exact 330750-20-05 configuration?

Require a clear nameplate and package photo showing 330750-20-05 in full. Cross-check every option against the official ordering table: 330750 = High Temperature Velomitor system; 20 = 2 m integral hardline cable; 05 = Multiple approvals (CSA, ATEX and IECEx).

Q2. How can I distinguish a new unit from a used or refurbished one?

Inspect the label, connector, cable, mounting surfaces and packaging. New hardware should not show installation marks, repaired cable, contamination, refinished surfaces or inconsistent date and serial labels.

Q3. How should I verify that the supplier is legitimate and reliable?

Check the supplier legal entity, business address, domain-based email, bank beneficiary and traceable quotation. Require the quotation and invoice to state 330750-20-05 in full and identify the Bently Nevada 330750/330752 High Temperature Velomitor System family.

Q4. Which technical details should an engineer confirm before purchase?

Confirm 2 m integral cable, 400 C sensor-head rating, 121 C electronics limit, 5.7 mV/mm/s sensitivity, MIL-C-5015 connector and 05 approval option. Verify the connected monitor or signal-conditioning chain and the installation environment before replacement.

Q5. What physical evidence should be requested before payment?

Request time-stamped photos or video showing the sensor head, 2 m hardline cable, separated electronics housing, MIL-C-5015 connector, full label and approval markings. Ask for close-ups that allow the ordering code and condition to be read without relying on a catalog image.

Q6. Can a similar suffix or related model replace 330750-20-05?

Not automatically. 330752 and other cable-length options have different mechanical arrangements or lengths and are not automatic substitutes. A replacement requires documented mechanical, electrical, environmental and approval compatibility.
