Product Overview
The HPT Series smart differential pressure transmitter is specially designed for accurate measurement of pressure difference between two points. By converting differential pressure into a standard industrial signal, it is widely used in flow calculation, liquid level monitoring, filter condition tracking, and pipeline leakage detection. Its applications can be summarized into three core categories:
- Flow measurement (oil & gas, chemical industry, energy, wastewater treatment)
- Level measurement (pressurized vessels in chemical & pharmaceutical industries, boiler drum level measurement)
- Process pressure/differential pressure monitoring (filter/heat exchanger monitoring, pressure & ventilation control in enclosed spaces)
Product Features & Advantages
- Advanced sensor technology: Uses second-generation monocrystalline silicon composite sensors or capacitive sensing structures with optimized diaphragm design, achieving accuracy up to ±0.075%, suitable for low differential pressure applications.
- Long-term stability: Long-term stability better than 0.1% per year, reducing calibration frequency.
- Environmental durability: Strong environmental adaptability with protection rating up to IP67 and excellent electromagnetic interference resistance.
- Flexible output & anti-interference: Supports 4–20mA analog output with HART digital communication overlay. Strong EMI resistance. Some models support customizable communication protocols.
- Remote configuration & calibration: Parameter setting and calibration can be performed remotely via HART, Modbus, or other protocols without on-site operation.
- Non-volatile memory: Built-in EEPROM ensures calibration data is retained even during power loss, enabling data recovery.
- Wide turndown ratio: Up to 100:1 turndown ratio, covering measurement from micro differential pressure (0–1 kPa) to high differential pressure (0–10 MPa).
- Temperature & pressure compensation: Built-in nonlinear compensation algorithms reduce measurement errors caused by environmental variations.
- Self-diagnostics & fast alarm :Monitors sensor, circuit, and communication status with fault detection and logging within 100 ms.
- Corrosion-resistant diaphragm materials: Options include 316L stainless steel, Hastelloy, and Tantalum for aggressive media applications.
- Data logging & event records: Stores key measurement data and event logs for traceability and analysis.
