▶ 제품명 : 절대압 트랜스미터(Absolute Pressure Transmitter),

절대진공을 기준으로한 절대압력을 고정도로 측정하는 트랜스미터로 자기진단 기능과 원격 쌍방향 통신기능은 분산된 지역에서 유지보수에 시간과 비용을 절감시켜드리며 압전영향(Piezoresistive)센서가 주위온도 및 압력을 보상 합니다.

* Carbon Steel heads are Zinc-plated. Not recommended for water service due to hydrogen migration.

Use Stainless Steel heads.  

** Vent/Drains are Tefron coated for lubricity.

*** If STA122 operating below 50mmHgA, see Figure 2 in Specification 34-ST-03-61 and contact Marketing Applications for a "Special" Silicone DC704 Quote.
