990 Vibration Transmitter e etselitsoe haholo bahlahisi ba lisebelisoa tsa mantlha (OEMs) tsa centrifugal air compressors kapa lipompo tse nyane, li-motor, kapa li-fan tse ratang ho fana ka lets'oao le bonolo la 4 ho isa ho 20 mA le thothometsang e le kenyelletso ho sistimi ea bona ea taolo ea mochini.

Transmitter ke terata e 2, sesebelisoa se nang le looppowered se amohelang ho kenya letsoho ho tsoa ho proximity probe ea rona ea 3300 NSv* le thapo ea eona ea ho atolosoa (e fumaneha ka likhetho tsa bolelele ba sistimi ea 5 m le 7 m).

Transmitter e beha lets'oao hore e be likarolo tse loketseng tsa boenjineri ba tlhōrō-to-tlhōrōng ea "vibration amplitude", 'me e fana ka boleng bona e le lets'oao le leka-lekaneng la 4 ho isa ho 20 mA indasteri e le tlhahiso ho sistimi ea taolo moo ts'ireletso ea mochini e tšosang le ho utloahala1.

Transmitter ea 990 e fana ka lintlha tse latelang tse hlokomelehang:

• Proximitor e Kopanetsoeng* Sensor ha e hloke yuniti e kantle
• Li-terminals tsa "PROX OUT" le "COM" tse sa arohaneng hammoho le sehokelo sa coaxial ho fana ka molumo o matla oa vibration le gap voltage signal output for diagnostics2.
• Li-zero tse sa sebelisaneng le li-potentiometer tsa span tlas'a label ea Transmitter li tšehetsa phetoho ea loop.
• Lekola Input pin bakeng sa netefatso e potlakileng ea tlhahiso ea lets'oao la loop, ho sebelisoa jenereithara ea ts'ebetso joalo ka kenyo.
• Potoloho e sa Lokileng/Signal Defeat e thibela liphetho tse phahameng kapa lialamo tsa bohata ka lebaka la proximity probe e fosahetseng kapa khokahanyo e hlephileng.
• Khetho ea li-clips tsa DIN-rail kapa li-screws tse kenyang li-bulkhead kaha likhetho tse tloaelehileng li nolofatsa ho hlongoa.
• Kaho ea lipitsa bakeng sa mongobo o phahameng (ho fihla ho 100% condensing) tikoloho.
• Ho lumellana le 3300 NSv proximity probe e lumella ho kenngoa ha transducer libakeng tse nyenyane tse nang le tumello e fokolang, e tloaelehileng ea li-compressor tsa moea tsa centrifugal.
