Perkenalan produk

This differential pressure sensor uses a silicon MEMS element to measure the small pressure differences found across cleanroom doors, walls, filters and airflow devices. Separate high and low ports accept clean tubing from the monitored and reference sides. The compact module can mount inside a room controller or protected enclosure, keeping the sensitive element away from direct handling. Temperature compensation and accessible zero adjustment support stable readings near zero where room-pressure decisions are made.

Fitur utama:

Rentang skala penuh rendah memberikan resolusi berguna untuk cascades tekanan cleanroom.

Barbed high and low ports keep the reference direction physically clear.

Temperature-compensated MEMS sensing reduces drift across normal indoor conditions.

Papan kompak atau format penutup terintegrasi ke dalam tampilan, pengontrol, dan pemancar.

Solusi untuk aplikasi Anda

Tekanan diferensial close-zero mudah terdistorsi oleh kesalahan tabung, sensor drift dan rentang pengukuran yang berlebihan.

Sensor jangkauan tinggi menunjukkan perubahan kecil di seluruh pita operasi ruang pembersih.Elemen MEMS jangkauan rendah memberikan resolusi lebih halus sekitar setpoint tekanan yang diperlukan.

Tabung terbalik membuat ruangan positif tampak negatif.Port tinggi dan rendah yang ditandai dengan jelas mengatur arah referensi yang dimaksud.

Small zero drift menciptakan alarm palsu ketika ruangan stabil.Penyesuaian nol yang dapat diakses dan kompensasi suhu mengurangi offset Dekat nol.

Eksposur langsung terhadap aktivitas pembersihan merusak elemen sensor.Tabung tekanan jarak jauh memungkinkan modul sensor untuk tetap dalam pagar terlindungi.
