Description
Overview
GAOTek high quality diaphragm pressure anemometer adopts diaphragm as a sensitive element, and it could choose different materials based on different measure mediums. The pressure gauge mainly applys to measure the micropressure of gas, liquid in industry of course, especially fits to medium of corrosion and viscidity, non-solidification and non-crystal. The pointer of the instrument will make contacts turn on or cut with the contacts of the set fingr, causing the cut and turn-on of the control system for the purpose of automatic control and alarm.
Features
- Minimum pressure is down to 4 KPa
- According to different corrosion-proof reguests
- Liquid filling models can be supplied
