TOP 6 Accessories for Submersible Level Transmitters

Submersible level transmitters are widely used for measuring liquid levels in tanks, wells, reservoirs, and wastewater treatment plants. To ensure stable performance and long-term reliability, choosing the right accessories is just as important as selecting the sensor itself. Holykell offers a complete range of accessories designed to enhance installation safety, extend product lifespan, and maintain accurate readings in challenging environments.

 

Below are the TOP 6 accessories for Level Sensors

1. Mounting Bracket – Secure Sensor Installation

The mounting bracket provides a simple yet effective way to suspend the submersible transmitter. By passing the cable through the bracket, users can easily hang the sensor at the desired depth without risking cable damage. This accessory is ideal for deep wells, water tanks, and open reservoirs where stable sensor positioning is crucial for consistent level readings.

2. Surge and Electrostatic Protector – Reliable Electrical Safety

The surge electrostatic protector safeguards the transmitter from sudden voltage spikes and electrostatic discharges. With protection levels up to ±2000V/±4000V for surges and 18KV for static electricity, it ensures long-term stability in harsh electrical environments. This is especially useful in industrial or outdoor installations where lightning or electrical interference may occur.

3. Desiccant Drying Cartridge – Prevent Moisture Condensation

Humidity inside the vented cable can lead to sensor drift or failure over time. The desiccant drying cartridge effectively absorbs moisture, preventing condensation and maintaining stable air pressure within the transmitter. This small but vital accessory helps extend the sensor’s service life, particularly in humid or coastal areas.

4. Terminal Box – Safe and Clean Wiring Connection

For installations exposed to rain, dust, or corrosive gases, a terminal box is essential. It provides a sealed enclosure for wiring connections, keeping them dry and corrosion-free. The box also simplifies maintenance by allowing easy access to electrical terminals without disturbing the sensor itself.

 

5. IP68 Deep Water Level Cable Extender – Extended Measurement Range

In deep-water applications, cable length is often a limitation. The IP68-rated deep water level cable extender offers a reliable way to extend the transmitter cable while maintaining waterproof integrity. Its rugged design allows for long-term submersion without compromising signal quality or sealing performance.

 

6. Threaded Flange – Secure Mounting for Tank Applications

When installing sensors in tanks or fuel systems, the threaded flange provides a stable mounting solution. It firmly secures the sensor at the top of the tank, preventing movement caused by vibration or liquid turbulence. This makes it particularly suitable for applications in oil storage, fuel management, and chemical tanks.

Universal Compatibility with HOLYKELL Submersible Sensors

All of these accessories are fully compatible with HOLYKELL submersible level transmitters, including models such as HPT604, HPT606, HPT611, and more. Each component is designed to work seamlessly with the sensor’s mechanical and electrical interfaces, ensuring easy installation and reliable performance across diverse environments.

Whether you are monitoring groundwater, wastewater, or fuel storage levels, combining your submersible transmitter with the right accessories will maximize accuracy, safety, and operational lifespan.
