Low Differential Pressure Gage

Transcription

1 Low Differential Pressure Gage Manostar Gage General purpose type Low Differential Pressure Gage RoHS compliant Broad line-up of product Supporting the air volume scale and the air velocity scale (refer to p.7) Readable wide-angle scale (Angle of the pointerrocation is 270 ) It is easy to convert polarity enable by piping Even when the pressure becomes excessive, the original mechanism avoid damage to moving parts. Small hysteresis is realized by the silicone rubber diaphragm. The pointer is not fluctated by the original bandlinked mechanism.
