SH 0526


• This type gauges have horizontal pressure element and also called Schaffer type.
• Horizantal Diaphragm (Schaeffer type) gauges are used to measure low pressure or low vacuum.
• Diaphragm is directly connected to movement, gauge readouts are swift and stable when compared to Bourdon tubed gauges
• All diaphragm groups are manufactured from AISI 316L. Hastelloy C276 or Monel 400 diaphragms can be manufactured upon request
• Diaphragm can be PTFE coated on request
• Diaphragm Separated types should be used if the process fluids are highly viscous, corrosive or cloggable, 
• Highly suitable for pressure measurement of viscous fluids or crystallisable mediums.
• Diaphragm groups which are used to measure low pressures.
• Can not be used in vibrating environments or with pulsating pressures.
Industry Sector: Petro-chemical plants, Mining industry, Machinery Manufacturing and Hydraulics/Pneumatics
