ZAXDP33 Differential Pressure Transmitter-Double Flange
The ZAXDP series intelligent pressure/differential pressure transmitters feature a central sensing unit utilizing advanced high-precision silicon pressure and differential pressure sensor technology. The sensors are positioned at the top of the metal housing, maintaining mechanical and thermal isolation from the medium contact surface. Integrated glass-sintered sensor leads ensure robust electrical insulation from the metal substrate, enhancing circuit flexibility and transient voltage protection capabilities. With platinum-grade accuracy of ±0.05% and unidirectional overpressure capacity up to 25MPa, the transmitters demonstrate exceptional static pressure performance. Their static pressure error is optimally controlled within ±0.05%/10MPa, while temperature influence remains minimal at ±0.04%/10K.

- Range
Please select a range code within rated range. Adjustable range within rated range
- Zero Point Settings
-
The zero point and range can be adjusted to any value within the measurement range of the meter, provided that the calibrated range is greater than or equal to the minimum range.
- Installation Position Affects
Keep installation position perpendicular to the diaphragm do not cause zero drift. However, if the installation position deviates from the diaphragm by more than 90°, a zero drift of <0.4kPa may occur. It can be corrected by adjusting the zero point and no effect to full range measurement.
- Output
Two-wire 4-20mA HART system compliant with NAMIR NE43 standards, linear or square root output are optional.
- Output Limit
Imin=3.9mA ,Imax=21.0mA
- Warning
If the sensor or circuit fails, The automatic diagnostic function outputs 3.9 or 21 mA.
- Alarm Current
Low mA mode: 3.9 mA/High mA mode:21mA. Default mode:High mA mode
- Response Time
The amplifier component has a damping constant of 0.1s; the sensor’s response time constant ranges from 0.1 to 1.6 s, depending on the range and range ratio. Additional adjustable response time constant is available from 0 to 100s.
