For customization, please provide details such as measuring range, cable length, output signal, and power supply.

Introduction

1. Advanced Design: The QDY30B is a submersible water level sensor designed for liquid level, pressure, and depth measurement. It features a robust anti-clogging protective filter probe that filters impurities in liquids, ensuring the durability of the sensor and the internal circuit board.
2. Durable Construction: Constructed with 304/316 stainless steel housing, it is hermetically sealed for compatibility with most industrial liquids and oils.
3. Leak-Proof Testing: Each welded housing is tested using a helium leak detector to guarantee superior protection. A ventilation tube within the cable automatically compensates for atmospheric pressure changes.
4. Long-Term Reliability: The cable conductors are isolated from the external environment to ensure long-term performance. The removable nose cone at the sensor protects the diaphragm from potential damage.
