Monocrystalline Silicon Differential Pressure Transmitter ( Model: SYDM-26 )

Monocrystalline silicon differential pressure transmitter is used to measure the differential pressure of liquid, steam or gas.
If some industry has high requirement, core components can adopt Endress+Hauser’s ceramic sensor and Manufacture technology.

 ● Turndown ratio: 100 : 1
 ● Accuracy option: ±0.075%, ±0.1%, 0.2%
 ● Span effect:
    > For accuracy 0.075% (Range code B – F):
when Turndown ratio is 1:1 ~ 10:1, effect is 0.075% of calibration range;
when Turndown ratio is larger than 10:1, effect is ±[ 0.002×Turndown ratio -0.1 ] %.
   > For accuracy 0.1% (Range code A – F):
when Turndown ratio is 1:1 ~ 10:1, effect is 0.1% of calibration range;
when Turndown ratio is larger than 10:1, effect is ±[0.025×Turndown ratio -0.125 ] %.
   > For accuracy 0.2% (Range code A – F):
when Turndown ratio is 1:1 ~ 10:1, effect is 0.2% of calibration range;
when Turndown ratio is larger than 10:1, effect is ±[0.03×Turndown ratio -0.1 ] %.
 ● Stability: within 36 months, error is ±0.2% of Maximum span
 ● Temperature effect:
   > For accuracy 0.075%: error of zero point or full Span is ±0.15% of Maximum span / 28℃
   > For accuracy 0.1%: error of zero point or full Span is ±0.2% of Maximum span / 28℃
   > For accuracy 0.2%: error of zero point or full Span is ±0.25% of Maximum span / 28℃
 ● Power supply effect: less than ±0.005% of calibration range / V
 ● Vibration effect: less than ±0.05% of Maximum span / g
 ● Installation effect: zero point drift is not more than 0.25Kpa, this error can be eliminated by zero point calibration, which does not affect instrument range.
 ● Electrical characteristics
    > Power supply (E ): 24VDC ( 10.5 ~ 36 VDC )
    > Output option: 4-20mA , 4-20mA(2-wire) + HART protocol
