Main features

Environment friendly

The use of a pushrod design eliminates the risk of resin contamination by the filling such as mercury.

Main specification

• Pressure transducing method : 4 edge bonded strain gauge type Wheatstone bridge.
• Range (Rated pressure) : Refer to pressure range code.
• Accuracy and Linearity :
  ±1.0% of span (Type exceeding 70MPa : ±2.0% of span)
  [When diaphragm temperature is 150°C]
  * For Hastelloy C : Contact to RKC
• Hysteresis :
  ±0.5% of span
  ±1% of span (Type exceedingr 50 MPa )
  ±2% of span (Type exceeding 70 MPa )
  Within ±0.2% of span (1MPa type)
  * For Hastelloy C : Contact to RKC
• Allowable maximum temperature of diaphragm : 400°C
• Allowable maximum temperature of diaphragm: 150°C
  * When the surface temperature of the lower part of the external case is
  134°C,  the  temperature of the strain gauge is 150°C.
  If the temperature of the strain gauge exceeds 150°C, performance cannot
  be maintained. Please isolate the sensor from the heat source by covering
  the heat source.
  Another solutions may include: Extending the sensor stem length, installing
  the sensor at an angle or horizontally, and so on. These methods are expected
  to suppress the temperature rise on the strain gauge.
• Allowable overload pressure : 120% of span
  [1000% of span for LLA type (0.5MPa), 500% of span for LLA type (1MPa)
• Marginal overload: 150% of span
  [2000% of span for LLA type (0.5MPa), 1000% of span for LLA type (1MPa)]
