• Application : Liquid , Gas and steam
• Pressure Range : 0 ~ 0.16kpa ~ 0 ~ 40Mpa
• Output : 4 ~ 20mA DC (banding adjustable damp)
4 ~ 20mA DC (stacking Hart. The digital signal)
• Power Supply : 12 ~ 45VDC(standare 24VDC)
• The Characterlize Load : It is related power supply and some one power
voltage is accur to appear as like Fig.1
Load resistance RL and power voltage VS formula is RL<50(VS-12)
Fig.1 The characterlize resistanc load.
• The display graph : There are 3kind of indication display,
1. 0 - 100 scale indicate line indication.
2. Root extraction 0-10 scale
3. 3? LCD display (0 - 100%)
• Explosive : Explosive proof : Exd IICT5 (MAX Amb 85°C)
Intrinsic safety : Exia IICT5
• Accuracy : ±0.20%, 0.25%, 0.50%. For details refer to the selection guide specification sheet.
• Stability : Within 6 months, error does not exceed the absolute value of the basic error with
reference to the maximum measuring distance.
• Measuring Range / zero point : It is available external control continiousely.
• Positive / Negative Transfer : The zero point will be transferred positive or negative,
Positive transfer : up to 500%
Negative transfer : up to 600%
• The positive / Negative maximum transfer will be limited 10% with in calibrations.
• Temperature : 1. -29 ~ +93°C (standard)
2. Component for silicon oil filled up : -40°C ~ +104°C
3. Flange type high-Temp silicon oil filled up : +15°C ~ +315°C
4. Standard silicon oil : -40°C ~ +150°C
• Static pressure over load : 4, 10, 25, 32 Mpa
※ See reference our model pressure table
• Humidity : 0 ~ 100%
• Capacity volume : <0.16 cm?
• Damper : When silicon oil filled up. 0.2 ~ 1.67S continuously can be controlled.
• Starting time : 2sec. (It is non necessary pre-heating)
• Zero and span Adjust : It can be adjusted outside
• Effect of vibration : With 200Hz frequency on a random axis, error is ±0.05%/g of the full scale
range.
• Effect of power supply : 0.005% / V of the transmission distance.
• Effect of load : No influence on the load if power supply is stable.
• Effect of installation location : Maximum 0.24 Kpa zero point error may occur, but it can be
calibrated and does not affect the accuracy of the full scale range.
• Structure material : Isolation membrance, 316L stainless steel, Hastelloy C-276, Monel or
tantalum.
Air / liquid vent valve : 316L stainless steel, Hastelloy C, Monel
