Pressure Switch

Pressure sensor / Pressure Switch adalah alat pendeteksi tekanan, baik tekanan berupa udara, air, oli atau steam, tekanan udara dihasilkan oleh kompresor, tekanan air dihasilkan oleh pompa air, tekanan oli dihasilkan oleh pompa oli atau hidraulic unit, sedangkan tekanan steam dihasilkan dari boiler atau sisa pembakaran generator dll.


Cara Kerja.

Didalam sensor ini terdapat kontak listrik sebanyak dua buah yaitu A kontak dan B kontak [ NO,NC ], namun ada juga yang hanya mempunyai satu kontak saja yaitu B kontak, ketika sensor mendeteksi adanya tekanan dibagian input, maka kontak-kontaknya akan bekerja, ini berarti A kontak terhubung dan B kontak terlepas.
Pada bagian dalam sensor terdapat baud “set” untuk mengatur besarnya tekanan yang akan dideteksi, pengaturan ini mempengaruhi cara kerja sensor, contoh sensor di atur pada setting rendah, maka ketika ada press atau tekanan yang masuk beberapa Kg/cm saja, maka sensor sudah dapat bekerja, begitupun sebaliknya.

Proximity Sensor

Sensor jenis ini banyak sekali digunakan di dunia industri..

“Proximity sensor” mencakup semua sensor yang melakukan penginderaan/deteksi secara non-kontak, dibandingkan dengan sensor lain, seperti limit switch, yang mendeteksi objek dengan fisik menghubunginya. Proximity Sensor mengubah informasi tentang gerakan atau kehadiran obyek menjadi sinyal listrik. Ada tiga jenis sistem deteksi yang melakukan konversi ini:


1.Sistem yang menggunakan arus eddy yang dihasilkan di obyek penginderaan logam dengan induksi elektromagnetik,

2. Sistem yang mendeteksi perubahan dalam kapasitas listrik ketika mendekati objek penginderaan.

3. Sistem yang menggunakan magnet atau reed switch .

Panduan Teknis mendefinisikan semua sensor induktif yang digunakan untuk mendeteksi benda-benda logam, sensor kapasitif yang digunakan untuk mendeteksi benda-benda logam maupun non-logam, dan sensor yang memanfaatkan medan magnet DC sebagai Proximity Sensor.

FBD vs Ladder

Pemrograman bahasa FBD (function block diagram) dan ladder digunakan untuk pemrograman PLC.

Mungkin pembaca berpikir seperti apa ya bahasa fbd itu??? jawabanya kalau yang sudah belajar pernah belajar sistem/teknik digital akan cepat mempelajarinya karena bahasa fbd itu bahasa dengan bentuk komponen IC sesungguhnya.

misalnya untuk logika and di fbd seperti ini :

dan untuk logika and di bahasa ladder seperti berikut :

Smart Relay Zelio

Smart Relay zelio merupakan keluaran dari schneider electric.

smart relay zelio biasanya digunakan untuk aplikasi-aplikasi kecil seperti pneumatic system dengan jumlah valve sedikit atau kurang dari 10. smart relay zelio hanya berupa contact relay.

Programming smart relay zelio menggunakan software zelio soft 2.

software tersebut dapat menggunakan bahasa ladder dan FBD (tergantung tipe smart relay untuk fbd), perbedaan bahasa ladder dengan fbd dapat anda lihat di sini. zelio soft juga ada sistem simulasi tanpa harus connect dengan smart relay zelio. untuk software zelio soft dapat klik di sini.

Moreover, ASEI will cover the insured from asset liability and protect the Obligee (Project Owner) from unfinished project development by the Principal (Contractor).
