The low-pressure sensor combines accurate measurement with stable long-term performance for industrial pressure monitoring. It features a -1~6 bar gauge pressure range, accuracy of ±0.25%FS, and ≤±0.1%FS/year long-term stability. Multiple analog outputs support flexible system integration, while the stainless steel construction and IP65 protection make the sensor suitable for liquid and gas pressure measurement in industrial equipment and automated control systems.
- Stainless Steel Construction: The all-stainless-steel structure provides good corrosion resistance and media compatibility for demanding measurement environments.
- Digital Temperature Compensation: The low-pressure sensor's advanced digital compensation helps maintain measurement accuracy when operating temperature changes across a wide range.
- High Accuracy and Fast Response: Provides accurate pressure readings with fast frequency response and stable performance for real-time pressure monitoring.
- Strong EMI and Lightning Protection: The low-pressure sensor has built-in protection against lightning, radio frequency interference, and electromagnetic interference, supporting stable operation in industrial environments.
- Short-Circuit and Reverse Polarity Protection: Integrated circuit protection helps reduce the risk of sensor damage caused by short circuits or incorrect wiring.
Applications
Designed for low-pressure measurement of liquid and gas media, the low-pressure sensor is widely used in industrial process control, automated inspection systems, machinery manufacturing, hydraulic and pneumatic systems, pump stations, and water treatment applications. The sensor provides real-time pressure data for process monitoring, automated control, equipment condition monitoring, and stable operation of fluid and gas systems.

Wiring Diagram
Q1: Can this low pressure sensor measure both liquid and gas?
A1: Yes. The low pressure sensor can measure both compatible liquid and gas media. The stainless steel construction provides good media compatibility for a range of industrial pressure measurement applications.
Q2: Can this low pressure sensor be used for pump stations and water treatment systems?
A2: Yes. This low pressure sensor can be used in pump stations and water treatment systems to monitor liquid pressure in pipelines, pumps, filtration equipment, and other fluid-handling equipment. Its -1 to 6 bar gauge pressure range, stainless steel construction, and IP65 protection make it suitable for many industrial water and fluid pressure monitoring applications.
Q3: What output signals this low pressure sensor are available?
A3: The low pressure sensor is available with 4–20mA, 0.5–4.5VDC, 0–5VDC, and 0–10VDC output signals. These options support integration with PLCs, industrial controllers, monitoring instruments, and automation systems.
Tips: What is the difference between a low pressure sensor and a standard pressure sensor?
A low-pressure sensor is optimized for measuring relatively low pressure, including pressure close to atmospheric pressure or within a vacuum-to-low-positive-pressure range. A standard pressure sensor may be designed for a wider or higher pressure range. The main difference is the rated pressure range and measurement performance within that range.
