Product Overview
The PTFE Coated Tuning Fork Level Switch is a point level detection instrument designed for monitoring liquid presence at a preset level. It uses vibrating fork technology to detect whether the sensing fork is covered by the process medium.
When the liquid contacts the PTFE-coated fork, the vibration condition changes. The internal electronic circuit detects this change and provides a switching output for level alarms or process control.
With PTFE-coated wetted parts, this level switch is suitable for applications requiring enhanced corrosion resistance, especially in chemical processing, wastewater treatment, and storage tank level monitoring.
Applications
Chemical Storage Tanks
Used for liquid level alarm in tanks containing corrosive chemical media.
Wastewater Treatment
Suitable for level monitoring in treatment tanks and chemical dosing systems.
Acid and Alkali Storage Systems
PTFE coating helps protect wetted parts against corrosive environments.
Industrial Process Vessels
Provides reliable high or low level switching for process automation.
Key Features and Benefits
1. PTFE Coated Wetted Parts
Provides improved corrosion resistance for aggressive liquid applications.
2. Reliable Point Level Detection
Detects liquid presence without mechanical moving parts.
3. Low Maintenance Design
The vibrating fork structure reduces mechanical wear and maintenance requirements.
4. Suitable for Industrial Tanks
Can be applied for high-level alarm, low-level alarm, and pump protection.
5. Flexible Configuration Options
Process connection, output signal, and installation configuration can be selected according to application requirements.

FAQ
Q1: What does a tuning fork level switch measure?
A tuning fork level switch detects whether liquid reaches a preset level point. It is used for point level monitoring rather than continuous measurement.
Q2: Why is PTFE coating used on the tuning fork?
PTFE coating improves corrosion resistance when the instrument contacts aggressive chemical liquids.
Q3: Can this product measure continuous liquid level?
No. A tuning fork level switch provides point level detection, such as high or low level alarm.
Please provide medium type, temperature, pressure, connection size, output requirement, and installation method.
