for High Temperature Applications
JC-50LHT Series
80GHz Radar Level Transmitter
The 80GHz radar level transmitter adopts the Frequency Modulated Continuous Wave (FMCW) radar principle. It emits high-frequency microwave signals, receives the echoes, and calculates the frequency difference to determine the level height.
Compared with conventional radar, our radar features a unique waveguide measurement method, independently developed by our company, which significantly enhances performance and reliability in complex applications.
· Oil & chemical storage tanks (diesel, gasoline, light oil, acids, alkalis)
· Solid silos (powders, granules)
· Water treatment plants, reservoirs, and pumping stations
· Mixing tanks, spherical and horizontal tanks
· Food & pharmaceutical reactors
| Key Advantages | Details |
|---|---|
| Unique Waveguide Design | Combines waveguide + horn antenna + focusing lens, achieving a beam angle of <2.5° (typical radars: 3–6°). Narrower beam angle ensures stronger echo signals and higher accuracy. Performs excellently in tanks with agitators, support rods, or other internal structures. |
| Self-Developed Radar Chip | Proprietary design with independent intellectual property rights. High integration: PLL, transmitter, receiver, baseband, and ADC are fully integrated, ensuring compact size. Low power consumption with advanced power management. Chip options: • CMOS silicon-based chip: 1.5dB stronger transmission power compared to TI chips, providing higher accuracy and stability in standard conditions. • GaAs chip: up to 18dB power output, designed for harsh conditions such as high temperature and high pressure, benchmarked against top international brands. |
| High Accuracy | Measuring accuracy up to ±2mm. Measuring range: (0.1 ~ 120) m. Stable and reliable signal processing, strong anti-interference capability. |
| Wide Applicability | Suitable for liquids, slurries, solid particles, powders, and corrosive chemicals (strong acids/alkalis). Compatible with tanks of different shapes: spherical, vertical, horizontal, reactors, or mixing tanks. Performs reliably under extreme temperatures, humidity, and pressure. |
| Flexible Installation | Standard process connection: G2 thread, optional G1.5, G1 (first G1 thread connection for 80GHz radar in China). Multiple flange options available (DN50, DN80, DN100, etc.). |
| Non-Contact Measurement & Low Maintenance | No mechanical contact with the medium, avoiding corrosion and wear. Long service life, minimal maintenance costs. |
What temperature range can this radar level transmitter reliably operate in?
This radar level transmitter operates in the frequency band of 80 GHz and is built for very hot conditions, as it does not only support continuous level measurement in vessels and tanks where temperatures can be high, but also provides continuous monitoring where the temperatures can reach very high levels. The device consists of internal parts and antenna materials that are carefully chosen so that they can soport and still perform well in a very hot environment. For the exact temperature limits, you can check the product specification sheet or ask our technical support team for compatibility with your process conditions.
How does the Bluetooth interface simplify setup and maintenance?
The Bluetooth interface that comes with the transmitter makes it possible to configure the device and conduct diagnostic tests without wires using a mobile phone. Technicians no longer have to access the control panel or to connect a laptop physically in a dangerous or difficult-to-reach area; they can use a Bluetooth smartphone or tablet to change parameters, monitor the system and perform diagnostic tests. All this boosts safety, cuts down on installation time, and increases efficiency on-site during commissioning.
Can this transmitter be integrated with modern industrial control systems?
This radar level transmitter has, indeed, several output protocols: 4–20 mA, RS485, and HART that give it the ability to be part of a vast array of industrial automation systems like PLCs, DCS, and SCADA platforms. Real-time level data can then be easily shared, stored, and used for process control, alarm triggers, or remote monitoring, which means that seamless integration into the existing control architectures is guaranteed.
Is there any maintenance required for high-temperature applications?
The maintenance of the device is generally not frequent mainly because of the robustness of the transmitter, but still, it is advisable to inspect the installation at regular intervals, especially in environments with heavy condensation or particulate exposure. Ensure the antenna surface remains clean and free of buildup, and check electrical connections for integrity. In most cases, the robust construction and thermal-resistant materials will reduce the frequency of maintenance compared to conventional sensors.
