PT-9200 IP68 submersible hydrostatic liquid level sensor with ceramic sensor core, vented cable, anti-clogging protective cap, and 4-20mA/0-10V outputs. Ideal for wastewater and tanks.
Product Overview:
1，The PT-9200 Submersible Liquid Level Transmitter is a high-reliability, cost-effective hydrostatic sensing solution engineered specifically for corrosive fluids, wastewater treatment, deep wells, water supply skids, and industrial tank automation. At its core, the PT-9200 incorporates a high-hardness, corrosion-resistant ceramic pressure sensor core, offering superior resistance to chemical erosion, acid/alkali attack, and high overpressure compared to standard silicon sensors.
2，Enclosed in a fully sealed IP68 304 stainless steel housing, the PT-9200 comes with a specialized vented cable that maintains internal atmospheric pressure balance, completely eliminating barometric measurement errors. Its liquid inlet features a removable protective cap to guard the ceramic membrane against sand, silt, and sediment buildup while making routine cleaning effortless. Driven by advanced digital temperature compensation and non-linearity correction, the PT-9200 provides 4–20mA and 0–10VDC analog outputs, backed by a 1-year warranty and private-label OEM/laser-marking options.
Key Features & Highlights：
1，Corrosion-Resistant Ceramic Sensor Core: High-purity ceramic core delivers exceptional immunity to chemical corrosion, acid/alkali exposure, and physical scraping in harsh liquids.
2，Vented Cable for Precision Gauge Reference: Integrated atmospheric ventilation tube balances internal cavity pressure with ambient air, eliminating barometric measurement drift.
3，IP68 SS304 Submersible Waterproof Casing: Heavy-duty 304 stainless steel housing with total IP68 submersion sealing ensures continuous operational longevity in fluid tanks.
4，Anti-Clogging Removable Protection Cap: Shields the ceramic sensing membrane from sand, silt, and mechanical impact, allowing quick removal for maintenance.
5，Advanced Conditioning IC & Digital Calibration: Precision signal processor delivers full-span digital thermal compensation and non-linearity correction for high dynamic precision.
6，1-Year Warranty & Custom OEM Branding: Backed by a 1-year warranty with customizable cable lengths, measuring depth ranges, laser etching, and private-label packaging.
Applications：
1，Wastewater & Environmental Engineering: Sewage basins, industrial wastewater pits, settling tanks, and chemical effluent monitoring.
2，Water Resources & Municipal Supply: Groundwater wells, river reservoirs, water towers, and fire protection tanks.
3，Petrochemical & Industrial Processing: Chemical holding tanks, cooling tower basins, fuel/oil pits, and automated fluid level control.
