The PR9268/301-000 est sensor passivus electrodynamicus velocitatis ex serie EPRO PR9268 Emerson, specifice constructus ad mensuram vibrationum absolutarum in carcasso machinarum turbinae criticarum . Constructus est ad installationem horizontalem, the PR9268/301-000 delivers a sensitivity of 28.5 mV/mm/s across a 4 to 1000 Hz frequency range . The PR9268/301-000 requires no external power supply and generates its output signal via electromagnetic induction. With a rugged aluminum housing, 5‑meter armored cable, IP55 rating, and ATEX/IEC‑Ex intrinsic safety certification, the PR9268/301-000 is ideal for harsh industrial environments on steam turbines, gas turbines, compressors, pumps, and fans .
Orientatio Montandi – Horizontal only, within ±10° of horizontal plane; no lifting/sinking current required .
Superficies Montandi – Secure firmly to bearing housing or machine casing using the threaded mounting hole (M8 or equivalent).
Directio Cavi – Use the 5‑meter armored cable; observe minimum bend radius to avoid damaging the PTFE insulation and stainless steel armor .
Electrica connectio – Standard Harting plug connector (or open cable ends depending on variant). Connect to a high‑impedance input circuit (nominally 100 kΩ) to maintain specified sensitivity.
Tegumentum – Usare cavo a coppia ritorta schermata per le estensioni; collegare lo schermo solo all’estremità del sistema di monitoraggio.
Grounding – Assicurare che la custodia del sensore sia collegata a terra tramite la staffa di montaggio per evitare loop di massa.
Funzionamento passivo e autonoma – Nessuna tensione di eccitazione esterna richiesta; genera il segnale tramite induzione elettromagnetica
Orientamento orizzontale – Ottimizzato per installazione orizzontale entro ±10° senza corrente di sollevamento/affondamento
Alta Sensibilitas – 28,5 mV/mm/s fornisce un segnale d’uscita forte per un monitoraggio affidabile delle vibrazioni
Latitūdō Frequentiae Latiōris – 4–1000 Hz copre macchinari a bassa e ad alta velocità
Construktio Robusta – Custodia in alluminio (Al Mg Si Pb F 28) con protezione IP55
Armored cable – 5‑meter PTFE‑insulated cable with stainless steel armor for durability
Certificatum pro Locis Periculosis – ATEX, IEC‑Ex, CSA intrinsic safety (ia) approvals
Low Transverse Sensitivity – 0.27 @ 110 Hz minimizes cross‑axis errors
The PR9268/301-000 is a seismic velocity sensor based on the moving‑coil principle. It consists of a permanent magnet fixed to the sensor housing and a coil assembly suspended by a spring system. When the machine casing vibrates, the housing and magnet move relative to the inertial coil mass. This relative motion causes the coil to cut through the magnetic field, inducing a voltage proportional to the relative velocity .
The sensor‘s mechanical spring‑mass system has a natural frequency of 4.5 Hz . Superius hac frequencia, voltatio exiens directe proportionalis est velocitati vibrationis per intervallum 4 ad 1000 Hz. Sensor est autoalimentatus et nullam excitationem externam requirit; tamen ad intritum alti impedimenti (100 kΩ nominalis) connectendus est ut sensibilitas specificata maneat. Exiens est signum voltationis alternantis quod proportionalis est velocitati absolutae vibrationis tegumenti machinae in axe horizontali.
Q1: Quae differentia inter PR9268/301-000 et alias variantes PR9268?
A1: Ille PR9268/301-000 specifice parata est pro horizontal fixatio (±10°). Variantes verticales includunt PR9268/20x-x00 (±30°) et PR9268/60x-x00 (±60° cum currente descendente). Sensibilitas et intervallum frequentionum etiam variant inter diversas formas.
Q2: Num PR9268/301-000 necessitat alimentationem externam?
Responsum 2: Minime. PR9268/301-000 est sensor passivus autoalimentatus qui signum suum exiens generat per inductionem electromagneticam. Nullam voltationem excitationis requirit sed ad circuitum intritionis alti impedimenti (100 kΩ nominalis) connectendus est.
Q3: Quae est maxima amplitudo vibrationis quam sensor mensurare potest?
A3: Limitis mechanicus est 3000 µm (4000 µm pico-ad-picum) . Sensor sustinere potest usque ad 10 g accelerationem continuam et 20 g intermittenter. .
Q4: Num PR9268/301-000 in locis periculosis uti potest?
A4: Ita. PR9268/301-000 certificatio intrinsecae securitatis (ia) pro ATEX, IEC-Ex, et CSA habet, quare idoneus est ad atmosphaeras explosivas (Zona 0/1).
Q5: Quae est longitudo normalis cavi et typus connexoris?
A5: Configuratio normalis includit cavum armatum quinque metrorum cum connexore Harting . Aliae longitudines cavi et optiones extremorum apertorum cavi disponibiles sunt ut versiones speciales.
