OEM Kacise 80GHz Compact Radar Level Transmitter KLD804 60m Radar Level Sensor

 5. Installation Requirements
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.

 
6. Electrical Connection
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).

8.Safety Guide
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.
9.Grade of Protection
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
10.Sensor linearity
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.
