Explosion Proof Solid 240℃ Radar Level Gauge Non Contact Type Radar Level Transmitter

904 radar level gauge installation must know three points

1. For the HBRD904 parabolic radar, the length of the standard antenna is short. In most cases, the antenna cannot be extended to take over the tube. Because the transmission angle of the parabolic antenna is smaller (4 °), when the tube is less than 300mm, the antenna will not have a small impact on the measurement (The antenna has the strongest signal when it reaches the tank).

2.HBRD904, when the takeover is larger than 300mm, you need to choose an extended parabolic antenna. The extended parabolic antenna will also affect the signal amplitude, so the ideal state during installation is to find a place where the thickness of the tank roof is thin, and it is not necessary to lengthen the antenna, such as the observation port.

3.Purge interface, the thread specification of solid-state radar purge interface is 1 / 8NPT, 8mm diameter fast purge connector on the interface

High-frequency radar level gauge parameters

1.temperature:Solid standard type: -40 ~ 130 ℃ High temperature type: -40 ~ 240 ℃ "；

2.application: Measurement of powder, granules, blocks and other solids;

3.output signal:RS485 output signal with single selection

4.Explosion proof:Single-cavity intrinsically safe explosion-proof type: Exia IIC T6 Ga, when using on-site in explosion-proof occasions, it is required to install a safety barrier in the control room；Double-chamber flameproof type: Exd IIC T6, no need for central control and no safety barrier when used in explosion-proof occasions. When on-site power is 220V, only dual-chamber radar can be selected.
