Level Measuring Instruments Description
Capacitive level gauges are instruments that measure the level of a medium within a container by utilizing changes in capacitance.
The capacitive level transmitter consists of two primary components: the Sensor Probe and the Transmitter Head.
Sensor Probe:
The sensing element inserted directly into vessels, reactors, or bypass chambers. Composed of a metal electrode and a high-insulation, anti-corrosive sheath (PTFE/PFA), it converts liquid level fluctuations into micro-capacitance variations.
Transmitter Head:
The control center of the instrument. It performs high-precision capacitance-to-current (C/I) conversion, converting the micro-capacitance signal into a standard 2-wire $4-20\text{ mA DC}$ output (HART compatible) for seamless integration with PLC/DCS systems.
Key Features:
No Moving Parts: Fully static solid-state structure eliminates mechanical wear, clogging, or jamming, ensuring minimal maintenance.
Harsh Condition Resilience: High-integrity sealing (ceramic-to-metal available) withstands extreme chemical corrosion, vacuum, high temperatures, and high pressures.
Flexible & Responsive: Instantaneous millisecond signal response with customizable mechanical designs (rod, cable, or coaxial) to fit non-standard installations.
Application Scenarios in the Chemical Industry
Strong Acids, Alkalis, and Highly Corrosive Media:
Storage tanks and neutralization pits containing highly aggressive chemicals such as hydrochloric acid, concentrated sulfuric acid, liquid caustic soda, and nitric acid.
High-Temperature and High-Pressure Vessels:
Process equipment subjected to extreme operating conditions, including polymerization reactors, hydrogenation reactors, and storage tanks for Liquefied Petroleum Gas (LPG) and liquid ammonia.
Viscous, Crystallizing, and Scaling Media:
Process and storage tanks handling sticky or solidifying substances such as tar, asphalt, high-viscosity resins, and various chemical slurries.
Sanitary Process and Preparation Vessels:
Hygienic storage and process vessels requiring strict contamination control, such as crystallizing tanks, fermenters, sterile dosing tanks, and Water For Injection (WFI) tanks.
Clean-in-Place (CIP) and Sterilize-in-Place (SIP) Systems:
Equipment subjected to aggressive chemical washing and thermal sterilization cycles, including cleaning agent preparation tanks and high-pressure sterilizing autoclaves.
High-Precision Small Reactors and Filling Lines:
Small-scale dosing and high-accuracy applications, such as laboratory autoclaves, benchtop pilot reactors, and small-volume buffer tanks in filling equipment.

What is the process for purchasing capacitive level sensor from Instrava supplier ?
1. Inquiry (We will respond to your inquiry within 24 hours to confirm specifications and initiate the process.)
2. Quotation (Quotation timelines vary based on the project type and your specific requirements. Standard stock items are quoted within one day, while special orders require three days or a mutually agreed-upon timeframe.)
3. Product Selection (We will present 3–5 product options and pricing for your approval. During this stage, we verify the manufacturer’s production capabilities and relevant national certifications.)
4. Contract, Prepayment, and Production (A 40% prepayment is required to initiate production at a qualified facility. For stock items, we promptly arrange for product testing and packaging.)
5. Interim Payment (Upon successful completion of production and quality inspection, the next 50% of the total amount is due. For stock items, this payment is made after packaging is complete.If the transaction amount does not exceed $50,000, the remaining 60% is paid.)

How to ensure the reliability of the purchased products?
Our customer-centric philosophy prioritizes their procurement needs.
1. Initially confirm the manufacturer based on product pricing and the strength and qualifications of the production factory.
2. Verify the manufacturer’s production environment through video and on-site inspections to check the compliance of the entire product manufacturing process.
3. Ensure post-production product testing and retain data and video evidence from the verification process(testing and verification methods vary depending on the product).
How does Instrava ensure product protection and physical safety during cross-border shipping?
Firstly, we confirm the packaged products with the factory (different products require different packaging and shipping methods. Heavy equipment and bulk shipments are securely secured within sea freight containers using custom-designed engineering steel frames, heavy-duty multi-layer wooden crates, and industrial-grade vacuum rust-proof bags. Precision instruments are protected against impacts and maintained in a stable position; the factory has extensive experience in this area. Custom labels are affixed to the outer packaging).
Secondly, we maintain communication with the freight company to confirm the condition of the goods and advise them to handle the loading and unloading processes with care.
What warranty policies and after-sales technical support does Instrava offer to international customers?
1. Instrava offers a comprehensive 12 to 24-month warranty (specific warranty period depends on the product line), covering all manufacturing and component defects.
2. When online technical support is needed, customers can connect with factory engineers online. Real-time guidance is provided for installation, on-site calibration (for instruments), and commissioning. When on-site engineer support is needed, we will arrange for an engineer to visit the site.
3. In the event of component issues, we will ship replacement parts via international express delivery (DHL/FedEx) to minimize your project downtime.
4. Whether a product requires replacement or repair will be clearly stated in the purchase contract.
