Deskripsi Produk
Instrumen Pengukuran Tekanan
SAF dan EAF membutuhkan pemantauan parameter tekanan utama termasuk tekanan ruang tungku, tekanan gas, tekanan air pendingin, dan tekanan sistem hidrolik untuk memastikan tekanan tungku stabil,keamanan peralatan, dan operasi proses yang tepat.
2.1 Transmitter Tekanan
| Jenis | Prinsip Pengukuran | Jangkauan Pengukuran | Keakuratan | Sinyal output | Aplikasi |
|---|---|---|---|---|---|
| Transmitter Tekanan Kapasitif | Perubahan kapasitas | -0,1 ~ 40MPa | 00,075% ~ 0,1% FS | 4 ~ 20mA+HART | Tekanan umum, tekanan diferensial |
| Piezoresistif Pressure Transmitter | Efek Piezoresistif | -0,1 ~ 60MPa | 00,1% ~ 0,25% FS | 4 ~ 20mA | Sistem hidrolik, pemantauan tekanan minyak |
| Transmitter tekanan yang disegel diafragma | Diafragma terisolasi | -0,1 ~ 10MPa | 00,1% ~ 0,2% FS | 4 ~ 20mA | Media yang mudah tersumbat, viskositas tinggi |
| Transmitter tekanan diferensial rendah | Resonansi kapasitif/silikon | 0 ~ 1 kPa | 0.1% FS | 4 ~ 20mA | Kontrol tekanan mikro diferensial tungku (± 15Pa) |
2.2 Saklar Tekanan
| Jenis | Pengaturan Jangkauan | Peringkat Kontak | Kelas Perlindungan | Fitur | Aplikasi |
|---|---|---|---|---|---|
| Saklar Tekanan Mekanis | -0,1 ~ 40MPa | 10A/250VAC | IP65 | Struktur sederhana, biaya rendah | Alarm tekanan tinggi/rendah, perlindungan interlock |
| Penukar Tekanan Elektronik | -0,1 ~ 60MPa | 0.5A/24VDC | IP67 | Keakuratan tinggi, titik pengaturan yang dapat disesuaikan | Pemantauan tekanan sistem kontrol otomatis |
2.3 Referensi Pilihan Instrumen Tekanan
| Skenario Pengukuran Tekanan | Instrumen yang direkomendasikan | Alasan Pemilihan |
|---|---|---|
| Tekanan ruang tungku (DP rendah) | Transmitter DP rendah (≤1kPa) | Keakuratan tinggi, stabilitas yang baik, kesalahan absolut <± 15Pa |
| Tekanan gas | Transmitter tekanan tertutup diafragma | Buktinya, tahan korosi |
| Tekanan air pendingin | Transmitter tekanan kapasitif | Tujuan umum, hemat biaya |
| Tekanan sistem hidrolik | Transmitter tekanan piezoresistif | Jangkauan yang luas, tahan benturan |
| Perlindungan alarm/interlock | Saklar tekanan | Tanggapan cepat, keandalan tinggi |
