Senex AP type intelligent absolute pressure transmitter differential pressure transmitter

Usage object: liquid, gas or vapor
Measuring range: Range 4 0-2.0~37.4kPa (0-15~280mmHg) absolute pressure
Range 5 0-4.7～186.8kPa (0-0.7～26.9 psia) absolute pressure
Range 6 0-17.3～690kPa (0-2.5～99.4 psia) absolute pressure
Range 7 0-51.7～2068kPa (0-7.49～298 psia) absolute pressure
Range 8 0-172.3～6890kPa (0-24.98～992.2 psia) absolute pressure
Output signal: 4~20mA output superimposed with HART® protocol digital signal (two-wire system)
Power source: external power supply 24V DC, (power supply range 12V~45V)
Load characteristics: Maximum load resistance allowed by the load resistance loop Rmax=(E-12)/0.02(Ω)
Installation in hazardous locations: explosion-proof dllCT6;
Intrinsically safe iallCT6
Load characteristics: Regardless of the output, after positive and negative transition, the upper and lower limits of the range must not exceed the limit of the range. The maximum positive migration is 0.975URL; there is no maximum negative migration L.
Temperature range: medium temperature -40～104℃
Storage temperature -40～85℃
Machine operating temperature -40～85℃
-20～70℃ (with digital meter);
Relative humidity: 0～100%
Overpressure limit: The pressure transmitter will not be damaged when 0 (absolute pressure) ~ 13.78MPa is applied; the flange can withstand 68.9MPa pressure; the normal working pressure should be between 0kP (absolute pressure) and the upper limit of the transmitter range.
Volume less than 0.16cm3
Damping: The time constant is adjustable between 0.2~32.0s.
Start-up time: 3s, no preheating required.

Performance indicators (under no migration, 316 stainless steel isolation diaphragm and other standard test conditions)

Range ratio: 40:1
Accuracy: Range is 3, 4, 5
When the range ratio is 1:1 to 10:1, it is ±0.15% of the adjustment range.
When the range ratio is 10:1 to 40:1, it is ±0.075 (1+0.1URL/range)% range
Stability: six-month error is ±0.2% of maximum range
Temperature influence: Zero point error is ±0.25%/55℃ of the maximum range
The total error inc range and zero point is 0.5% of the maximum range/55℃.
Effect of overpressure: After pressurizing 140kgf/cm2, the error is ±0.25% of the maximum range.
Power supply influence: less than 0.005%/V of the output range
Vibration effect: in any axis direction, the frequency is 200Hz, the error caused is ±0.05%/g of the maximum range
Load influence: As long as the input voltage of the transmitter is higher than 12V, there is no load influence in the load working area.
Influence of installation position: The maximum zero error can be no more than 0.25 kPa, but it can be corrected and has no effect on the measuring range; the rotation of the measuring body relative to the flange has no effect.
