▶ Excellent anti-corrosion,waterproof,and impact-resistant properties;
▶ IP68 protection rating,fully potted enclosure,unaffected by temperature variations
on sealing performance;
▶Built-in high-capacity battery;
▶ Batteries with low self-discharge enable devices to achieve longer battery
li fe performance;
▶ Awarded:Multiple patents and software copyrights;
▶Obtained:IP68 test report issued by a CMA-accredited organization
recognized by the China National Certification and Accreditation
Administration Committee;
▶Selected into the "National Water Resources System Key Procurement Catalog for Bidding Products."
◆Application Scenarios
This product,featuring a digital diffused silicon pressure senso as its core component,demonstrates significant application value.With its buil-in battery,it eliminates the need for additional wiring and power supply,ensuring exceptional ease of use.
On one hand,it enables precise monitoring of terminal pressure in firefighing pipelines,reinforcing fire s afety defenses.On the other hand,it excels in municipal water supply applications by providing real-time monitoring of residential areas,weak points in water distribution networks,and terminal pressures-ensuring stable water supply for residents.Moreover,through continuous pressure data collection,it offers critical referen ces foreffectively reducing and controlling water supply energy efficiency,thereby faciitating refined manage ment of municipal water systems.
Additionally,this product is widely applicable for monitoring pipeline and tank pressures in both industria land civil equipment.The measured data is rapidly transmitted to servers via 4G signals,enabling real-time pressure monitoring across vanious scenarios and ensuring comprehensive system safety and operational efficiency.

- When equipped with RS485 communication output, battery power supply is not supported.
- Anti-clogging accessories are optional for C-type split cable hydrostatic sensors, but mandatory for L-type wall-mounted and Q-type wall-mounted hydrostatic sensors.
- For input signals of diffusion silicon or ceramic capacitive sensors, the only available process connection option is "without mounting bracket".
- For pressure sensor inputs:
- When measuring water level: Cable length is calculated based on (sensor range / 2).
- When measuring pressure: Cable length follows customer requirements; if not specified, the default standard length is 1.5 meters.
- Built-in lithium battery capacity specifications:
- C-type split and E-type integrated structures: 19000mAh
- L-type wall-mounted stainless steel housing: 76000mAh / 133000mAh / 266000mAh optional
- N-type clamp-on stainless steel housing, Q-type wall-mounted split plastic housing, G/H-type direct-mount plastic waterproof enclosure: 76000mAh
