상품 소개

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.

주요 기능

Low full-scale ranges provide useful resolution for cleanroom pressure cascades.

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

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

Compact board or enclosure formats integrate into displays, controllers and transmitters.

고객 제품 관심사

Near-zero differential pressure is easily distorted by tubing errors, sensor drift and excessive measurement range.

A high-range sensor shows little change across the cleanroom operating band.A low-range MEMS element provides finer resolution around the required pressure setpoint.

Reversed tubing makes positive rooms appear negative.Clearly marked high and low ports preserve the intended reference direction.

Small zero drift creates false alarms when the room is stable.Accessible zero adjustment and temperature compensation reduce offset near zero.

Direct exposure to cleaning activity damages the sensing element.Remote pressure tubing allows the sensor module to remain in a protected enclosure.
