Question 1

What is the difference between a monitor and a transmitter?

Accepted Answer

A monitor (like the 3500/42M) lives in a protection rack: it drives alarms and trips locally and reports to the DCS. A transmitter (like the 3300/65A) packages the full measurement chain in one loop-powered device and delivers a 4–20 mA signal straight to the PLC — no rack, no trip logic, lower cost. Monitors are for machines where the trip decision must sit in the protection system; transmitters are for smaller machines where the PLC handles alarming. Both have their place, and we stock both.

Question 2

How should I store spare 3500 modules?

Accepted Answer

Three rules: keep them in their ESD packaging until the moment of installation, store them in a dry room-temperature cabinet (not on top of the rack, not next to transformers), and keep the configuration memory intact by avoiding unnecessary handling. Modules do not need periodic powering in storage, but the cabinet should be frost-free and free of condensation. Label the shelf with the module type and slot it serves — a spare that takes twenty minutes to find is not a spare.

Question 3

How can I get a quote or a retrofit plan?

Accepted Answer

Send us the list — model numbers, nameplate photos, or even a photo of the rack — through the contact form or WhatsApp. Within one business day you receive a line-by-line quote with availability and lead time. For retrofit planning, include the machine train and what you want to achieve (system renewal, obsolescence cover, or spare-pool build-up) and we will return a staged plan: what to keep, what to replace, and in which order to buy.

Question 4

Are your Bently Nevada products genuine and factory-new?

Accepted Answer

Yes. Every module we ship is either factory-new in original packaging or a tested surplus part that is explicitly labelled as such on the quote — never refurbished without disclosure, and never counterfeit. Surplus units are functionally tested, cleaned, and packed with ESD protection, and carry our own warranty on top of the description. If you require factory-sealed stock only, say so in the inquiry and we will quote accordingly.
