Monocrystalline Silicon Differential Pressure TransmitterModel:SYDM26

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

● Load (R) characteristic:



Parameter of intrinsically safe explosion-proof: Ui=28VDC, Ii=93mA, Pi=0.65W, Ci=0μF, Li=0mH
Electromagnetic compatibility: comply with IEC 61000-4
