Kacise OEM 80G Radar Level Transmitter with 80GHz Frequency 50m Range and IP67 Protection

The Kacise OEM 80G Radar Type Level Transmitter is a remarkable device. Operating at 80G frequency, it offers high precision in level measurement. With a maximum range of 50m, it can accurately monitor liquid or solid levels in various industrial tanks and vessels. Its radar technology enables reliable operation even in challenging environments with dust, vapor, or fluctuating temperatures. The transmitter is designed with advanced features for enhanced stability and durability. It provides accurate and real-time level data, which is crucial for efficient process control in industries such as chemical, petrochemical, and food and beverage. Its compact and robust construction makes it suitable for both indoor and outdoor installations, ensuring seamless and accurate level monitoring.

The radar antenna transmites narrow microwave pulse which will be reflected back when reaching the surface of the medium tested and then received again by the antenna system. The signals shall be transmitted to the electric circuit and then converted into level signals. As the transmission speed of microwave is so fast, the time used for the microwave transmission to the surface of the medium tested and then reflected back is almost 0.

• Millimeter wave radar, the measurement accuracy can reach up to ±2mm, and the minimum measurement blind zone is 0.05m.
• The smaller antenna size satisfies the measurement of more working conditions.
• A variety of lens antennas, smaller launch angles, more concentrated energy, stronger echo signals, and higher reliability than other radar products under the same industrial and mining conditions.
• It has stronger penetration and can be used normally in the case of adhesion and condensation.
• The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable.
• Multiple measurement modes, radar response in fast measurement mode

When installing the instrument, avoid installing it above the material inlet, and try to avoid various objects that affect the signal, such as stirring paddles, etc.

Power Supply
(4～20) mA/HART(2 wire)
The power supply and the output current signal share a two-core shielded cable. Please refer to the technical data for the specific supply voltage range.
(4～20) mA(4 wire/6 wire)
The power supply needs to be powered separately, and a four-core shielded cable is used for the power supply and current signal (the current signal and the RS485 interface can be output at the same time, and a six-core shielded cable is required for simultaneous output).
RS485/Modbus
The power supply needs to be powered separately, and a four-core shielded cable is used for power supply and digital signal. (The current signal and the RS485 interface can be output at the same time, and a six-core shielded cable is required for simultaneous output).

Please observe the requirements of the local electrical installation regulations! Follow local regulations for personnel health and safety. All operations on the electrical components of the instrument must be completed by professionals who have received formal training. Please check the nameplate of the instrument to ensure that the product specification meets your requirements. Please ensure that the power supply voltage is consistent with the requirements on the nameplate of the instrument.

This instrument fully meets the requirements of protection class IP66/67, please ensure the waterproofness of the cable sealing head. As shown below:

How to ensure that the installation meets the requirements of IP67:
Make sure the sealing head is not damaged.
Make sure the cable is not damaged.
Please make sure that the cables used meet the requirements of the electrical connection regulations.
Before entering the electrical interface, bend the cable down to ensure that water will not flow into the housing, see ①
Please tighten the cable gland, see ②
Please plug the unused electrical interface with a blind plug, see ③

Beam Angle
The beam angle is the beam angle at which the energy density of the radar wave reaches half of its maximum value (3dB width). Microwaves emit signals out of beam range and can be reflected by interfering objects.

The larger the antenna size and the smaller the beam angle α, the less interference echoes will be generated.
For more accurate measurements, avoid installing any internal devices (such as limit switches, temperature sensors, bases, vacuum rings, heating coils, baffles, etc.) within the range of the signal beam.
