High Quality Factory Directly Low Differential Pressure Sensor

High accuracy
0.2% accuracy for all calibrated spans is the standard feature for pressure transmitter covering 40 to 3000kPa, 0.1% accuracy as option. The compositive monocrystalline piezoresistive sensor assures this accuracy for all elevated or suppressed calibration ranges without additional adjustment.

Minimum environmental influence
The Advanced Cell design, which protects the pressure sensor against changes in temperature, static pressure, and overpressure substantially reduces total measurement error in actual field applications.

Span, range
Working pressure Span (kPa abs) Range (kPa) Over range
Type (kPa abs) Min. Max. LRL URL MPa
SKA 01 0~40 2 40 0 40 0.12
SKA 02 0~250 2.5 250 0 250 0.75
SKA 04 0~3000 30 3000 0 3000 9 Note: LRL= Lower Range Limit; URL= Upper Range Limit.
To minimize environmental influence, span should be greater than 1/40 of the max. span in most applications.

Process temperature
(-40~85)℃
(-20~85)℃(for explosion proof units)

Performance Specifications for Linear Output
(Zero-based calibrated ranges, reference conditions, silicone oil fill, 316L SST isolating diaphragms and 4 to 20mA analog output in linear mode.)

Accuracy rating (including linearity, hysteresis, and repeatability)
Standard:For spans greater than 1/10 of URL: ±0.2% of span Option(21st digit: H,Not available for 40kPa abs and 250kPa abs):
For spans greater than 1/10 of URL: ±0.1% of span
Temperature effect
Effect per 28℃ change between the limits of -40℃ and +85℃
Over range effect
Zero shift: ±0.2% of URL for any over range to maximum limit
Stability
±0.2% of upper range limit (URL) for 10 years.
Mounting position effect
Zero shift: less than 0.1kPa for a 10° tilt in any place .No effect on span. This error can be corrected by adjusting zero.
