Description wet/wet differential pressure transmitter water

The capacitive pressure transmitter combines the international advanced digital technology, and uses a digital circuit to replace the analog signal amplifier circuit and A/D conversion circuit, which improves the measurement accuracy. It adopts standardized installation structure design, easy to install and use, the sensitive diaphragm has one-way overload protection capability, the maximum withstand voltage is 320bar, and it has the characteristics of high reliability and good long-term stability. Capacitive pressure transmitters are divided into gauge pressure type, absolute pressure type and differential pressure type.
The capacitive transmitter has built-in high-performance digital circuits, carefully designed for radio frequency, electromagnetic interference, and surge voltage conditions. It has the characteristics of strong anti-interference ability, wide power supply range, and polarity protection, and conforms to IEC, CE (EMC) standard. Anti-radio frequency and electromagnetic interference; the intelligent digital temperature compensation circuit stores the calibration value corresponding to the temperature change in the chip, and can automatically compensate when the sensor is affected by temperature, which solves the temperature drift phenomenon of the sensor and improves the measurement accuracy and environmental adaptability of the sensor.

Specification wet/wet differential pressure transmitter water

Operating temperature of the whole machine -40~+85ºC (without LCD meter) -30~+60ºC (with LCD meter)
Ambient temperature -0~-100% relative humidity
Temperature influence ±(0.2%URL+0.18% inspection range)/56ºC
Power influence Less than 0.0059%/V of output range
Load influence No load influence, unless the power supply voltage changes
Vibration influence: Vibration influence is ±0.05%URL/g at 200Hz in any axial direction
EMI/RFI influence From 20 to 1000MHz, when the field strength reaches 30V/M, the output drift is less than ±0.1% of range
The installation position affects the maximum zero drift of ±0.25kPa, all zero drifts can be corrected; the impact on the range blockade
Positive and negative zero migration When the zero migration is negative, the lower limit of the range must be greater than or equal to -URL;
When the zero point is shifting positively, the upper and lower ranges must be less than or equal to +URL. The calibration range must be greater than or equal to the minimum range
Zero point and range can be adjusted with the range and zero point buttons of the machine, or remotely adjusted with a HART handheld
Static pressure and overpressure limit Adding a pressure of 0 to 13.79MPa on either side of the transmitter will not cause damage. Meet performance specifications when working within the range of 0kPa to the upper limit of the transmitter range
Damping time constant The time constant is adjustable, in 0.1 second increments, from the minimum to 16.0 seconds
Explosion-proof grade Intrinsically safe type: Exia II CT6 Explosion-proof type: Exd II BT5
Protection grade IP65
Key operation:
Support HART protocol Support button to set range, set unit, set damping, reset, calibration, etc.
