• 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.
