  1. PRESSURE SENSOR CREATED BY : ARISSETIAWAN (29850) J. TULUS S. (29231) HERI SUTANTO (29616) CINDRA P.A. (29859) SAPUTRA D.N. (29953) DEDDY PRIMA (29258)

  2. PRINSIP PRESSURE • Static Pressure : Fluida tak bergerak / diam • Dynamic Pressure : Fluida bergerak • Gauge Pressure : Pg = Pabs – Patm • Unit : Satuan-satuan yang terkait  P=F/A • Head Pressure : P=ρgh; ρ=m/v; P= ρwh

  3. JENIS-JENIS SENSOR • Bourdon Tubes • Bellows • Semiconductor Pressure Sensors

  4. Bellows

  5. Semiconductor Pressure Sensors

  6. Bourdon Tubes PrinsipKerja sejenispipapendeklengkung , dansalahsatuujungnyatertutup. Jika bourdon tubes diberikantekananmakaiaakancenderunguntuk “menegang”. Perubahan yang dihasilkansebandingdenganbesarnyatekanan yang diberikan.

  7. Bourdon Tubes

  8. KELEBIHAN • Tidak mudah terpengaruh perubahan temperatur • Baik dipakai untuk mengukur tekanan antara 30-100000 Psi KEKURANGAN • Pada tekanan rendah 0-30 psi kurang sensitif • dibanding bellows

  10. The Armfield Pressure Measurement and Calibration unit has been designed to introduce students to pressure and how different techniques can be employed to measure this variable. Different fixed pressures are generated using a simple Dead-weight Pressure Calibrator for the purpose of calibrating the measuring devices. • A Bourdon type pressure gauge and electronic type pressure sensor are connected to the calibrator to allow their characteristics, including accuracy and linearity, to be determined.
