HMHP Capacitive high static pressure differential pressure transmitterDetailed product description：

HMHP capacitive high static pressure differential pressure transmitter

Target audience: liquids, gases, or vapors
Measurement range: 0-6Kpa to 0-180KPa
Output: 4-20mADC
Power supply: 24VDC, no load transmitter can operate at 12VDC, up to 45VDC
Positive and negative transfer:
Regardless of the output, after positive and negative scaling, the upper and lower limits of the range must not exceed the limit of the range.
Maximum positive transfer amount -500% of the minimum calibration range;
Maximum negative transfer -600% of the minimum calibration range
Temperature range:
Amplifier operating temperature -25~+90 ℃; Sensor operating temperature -40~+104 ℃
Relative humidity: 1-100%
Sensor volume change: less than 0.16cm3
Damping: The time constant is continuously adjustable between 0.2 and 1.67 seconds.
Indicator (on-site): pointer type, digital display type

Explosion proof type:
Explosion proof type ds Ⅱ BT5 intrinsic safety type ia Ⅱ CT5
Range and zero point: externally continuously adjustable
Static pressure and overpressure limits:
Maximum working static pressure 40Mpa
Maximum safe static pressure 42Mpa
Unidirectional maximum pressure 32Mpa
Flange pressure resistance 60Mpa
Static pressure effect:
Zero point error: When the working pressure is 32MPa, the zero point error is ± 2% of the maximum range.
Range error: The error is ± 2%.
This is a systematic error, which can be adjusted according to the actual static pressure before installation to eliminate the error.
Start time: 2 seconds, no preheating required.

performance metrics
(Note: Tested under non migration, 316 stainless steel isolation diaphragm and other standard conditions)
Comprehensive accuracy: ± 0.25% of the calibration range
Stability: ± 0.25% of maximum range (six months)
Temperature impact:
In the maximum range state:
Zero point error is ± 0.5% of the measuring range/55 ℃
The total error of zero point and range is ± 1.0% of the range/55 ℃
In the minimum range state:
Zero point error is ± 3.0% of the measuring range/55 ℃
The total error of zero point and range is ± 3.5% of the range/55 ℃

Overpressure impact:
For different ranges, according to regulations, the overpressure error is within ± 1% to ± 5% of the maximum range.
Vibration impact:
In any axial direction, at a frequency of 200Hz, the error caused is ± 0.05%/g of the maximum range.
Power supply impact:
Less than 0.005%/V of the output range.
Load impact:
As long as the terminal voltage of the input transmitter is higher than 12V, there will be no load impact.
Installation location impact:
The maximum zero point error that can be generated is 0.24Kpa, but it can be calibrated and has no impact on the measurement range.
