DP Series Smart Pressure Transmitter


Accuracy

 

Linear Output : ± 0.075% ~ ±0.1% (span ratio 1:1) including comprehensive inaccuracy of linear, changing difference and repeatability.

 

Evolution Output : ± (0.2% of calibrating measuring range + 0.05% of upper limit) at time of 4~100% output pressure.

 

Stability : For DP span code 3, 4, 5, it is ±0.2% of the highest span; for other code, it is ±0.25% of the highest span.

 

Main features


Output Signal : 4 ~ 20 mA DC

 

Transmission Form : Two-wire system.

 

Humidity : 0 ~ 100% relative humidity.

 

Starting TIme : At most 2 seconds for minimum damping.

 

Volume Change : Less than 0.16 cm³.

Damping : Electrical damping is 0 ~ 32 seconds, continually adjustable at an interval of 0.1 second. Sensitive components have 0.2 seconds constant damping time. (Span 3 is 0.4 seconds).

 

Zero Point Inaccuracy : ±0.25% of highest span for 14Mpa; ±0.5% of highest span for Span3, correct through adjustable zero-point.

Span Inaccuracy : Each 6Mpa can be connected to ±0.25% of input reading. This accuracy can be eradicated before mounting.

 

Zero Point (Effect of Temperature) : ±3% of span for each 100°F (56°C).


Total effect includes span and zero point inaccuracy:±3.5% of span for each 100°F(56°C);
For Span 3, the effect doubles.


Shock Effect : At time of 0 ~ 200 Hz of shock frequency on any direction, the error is 0.05%/g of the highest one.


Power Effect : Less than output range by ±0.005%/V.
Installation Position Effect : Zero drifts no more than 0.24kPa. The error could be resolved by zero reset and has no effect on measuring range.

 

Separation Spacer : 316L Stainless Steel, HC-276, Monel or Ta.


Exhaust Valve : 316 Stainless Steel, H or Monel.


Filling Liquid : Silica Oil


Bolt : Cadmium plated carbon steel.


Electronic Circuit : Low Cu Al.
Pressure Connection Part : ¼ - 18 NPT for joint thread in pressure room,
½ - 14 NPT for joint thread in pressure guiding joint.
