1. Dimensions of Instruments
l The rod antenna radar size (unit: mm)
l Flange Selection (unit: mm)
2. The Electrical Connection
l The power supply voltage:
| (4~20)mA/HART (Two wire system) | The power supply and the output current signal sharing a two core shield cable. The supply voltage range see technical data. For intrinsically safe type must be a safety barrier between the power supply and the instrument. |
| (4~20)mA/HART(Four wire system) | Separate power supply and the current signal, respectively using a two-core shielded cable. The supply voltage range see technical data. |
| RS485 / Modbus | Power supply and Modbus signal line are separated, respectively using a two-core shielded cable, the power supply voltage range see technical data. |
l Connection mode:
Ø 24V two wire wiring diagram as follows:
Ø 220V four wire connection is as below:
Ø 6~24V RS485/Modbus wiring diagram as follows:
l Explosion Proof Connection
The intrinsic safety version sensors (Exia IIc T6) use Alu-die casting housing and filling Silicone rubber sealants internal structure aimed to prevent sparks resulted from circuit failure from leaking out. It is applicable for the continuous level measurement of flammable medium under Exia IIc T6.
A safety barrier FBS-2 must be used together with the intrinsic safety instrument. It is an associated device to this product for the power supply of this product. The main specification is intrinsic safety: Exia IIC, voltage of power supply: 24V DC±5%, short-circuit current: 135mA, operating current: 4...20mA.
All cables must be shielded. The max length is 500m for the cable from the barrier to the sensor. Stray capacitor≤0.1μF/Km, stray inductance 1mH/Km. Instrument must be connected to the ground potential. Any unapproved associated device is not allowed to be used.
