Typical Applications
Pressure measurement of viscous/easily crystallizing media (e.g., pulp, syrup, resin):
The sensing element of the HNP30-AC sits at the top of the metal housing, offset from the wetted diaphragm to create full mechanical isolation. Minor buildup on the diaphragm will not throw off measurement accuracy. Paired with its one-touch zero trim function, the unit simplifies safe on-site calibration and maintenance work.
Corrosive media environments (e.g., hydrochloric acid, sulfuric acid, seawater):
Optional corrosion-resistant diaphragm materials such as Hastelloy C, Monel, tantalum, and titanium are available, making it fully adaptable to harsh media such as strong acids, strong alkalis, and seawater. The single-crystal silicon sensor is located at the top of the metal body, completely isolated from corrosive media. Even if the diaphragm is in long-term contact with corrosive media, the sensor core remains uncorroded.
Why Choose our product ?
1. Adjustable span ranges and multiple accuracy grades available to match site-specific measurement requirements.
2. Rated for up to 25 MPa overpressure and fitted with digital isolation circuitry to block electrical noise. Once installed, it needs minimal servicing and cuts long-term maintenance overheads drastically.
3. Flush diaphragm construction prevents clogging. Seven wetted material options including Hastelloy, tantalum and titanium are offered, making the transmitter suitable for thick, crystallizing fluids and harsh acidic or alkaline process media.

|
Measurement Principle |
The pressure transmitter utilizes a monocrystalline silicon sensor to convert pressure signals into electrical signals, which are then processed by a microprocessor with dual compensation technology. It communicates through the Hart protocol and is equipped with an external one-key reset function, achieving high-precision and interference-resistant pressure measurement. |
