Are you still paying the price for errors from traditional level meters?

Every measurement deviation may mean tens of thousands of yuan in wasted raw materials, or an unplanned shutdown for maintenance.

KJT 78 GHz millimeter-wave radar level and material level meters redefine the boundaries of reliable industrial measurement with extreme ±1 mm accuracy.

Say goodbye to rough estimation and enter a new era of precise sensing.

Key Specifications

Range coverage: 0.08 m to 20 m, covering scenarios from small tanks to large deep silos.
Measurement accuracy: ±1 mm, enabling true millimeter-level management.
Process connection: multiple flange and thread options, compatible with most existing interfaces.
Signal output: 4–20 mA, HART, RS485, Modbus, and more, enabling seamless integration into DCS/PLC systems.
Protection rating: IP67 + IEC 62561 lightning protection certification, built for harsh outdoor environments.
Temperature range: -40°C to 80°C, stable from extreme cold to hot workshops.

Core Pain Points: Is Your Factory Facing These Problems?

Storage tank uncertainty: How much raw material remains? Relying on experience-based estimates keeps purchasing and production in constant conflict.

Dust-heavy environments: In cement silos and powder tanks, traditional radar signals are severely attenuated, causing unstable data.

Weather dependence: In rain and fog, ultrasonic and laser instruments may “go blind,” forcing production data interruptions.

Installation limitations: To avoid agitators and baffles, users often accept large blind zones and sacrifice usable storage capacity.

KJT’s Solution: 78 GHz High-Frequency Millimeter Wave — Penetration Is Productivity

Why 78 GHz?

A higher frequency brings a narrower beam angle, only 8°, and stronger penetration.

This means:

1. More precise targeting: concentrated energy ignores internal obstacles and reaches the liquid or material surface directly.

2. Smaller blind zones: top-mounted installation allows measurement even near tank walls, releasing more storage space.

3. Stronger penetration: easily handles high dust levels up to 500 g/m³, steam, light mist, and other complex conditions.

Value: How Does Precision Convert into Profit?

In chemical plants, continuous ±1 mm precision monitoring can directly reduce raw material waste by 3%, creating million-level annual profit.

In cement plants, stable level monitoring through 50 g/m³ high-concentration dust helps prevent overflow accidents, saving up to 410,000 yuan in cleaning costs and shutdown losses.

Accuracy is a visible cost factor — and a measurable return.

From Urban Flood Control to Water Purification

At drainage management centers, real-time radar water level data links with flood control systems, increasing rainstorm warning response speed by 40%.

At wastewater treatment plants, ±1 mm water-level control helps maintain optimal inlet pressure, improving air flotation process efficiency by 18% and reducing sludge volume.

It is more than an instrument. It is a data foundation for intelligent decision-making.

Why KJT?

Because we do not just provide hardware. We provide certainty-based solutions.

1. More precise positioning: self-developed optical structure and intelligent algorithms.

2. Stronger protection: IP67 protection rating, with quality built to withstand testing.

3. Greater penetration: 78 GHz ultra-narrow beam for outstanding performance in complex environments.

4. Easier domestic substitution: as an early mover in domestic sensor replacement, KJT delivers reliable performance comparable to international brands at a better cost-performance ratio.
