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  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 capacitor0.1μF/Km, stray inductance 1mH/Km. Instrument must be connected to the ground potential. Any unapproved associated device is not allowed to be used.


3.  Protection Grade :

 This instrument meets the protection class IP66/67 requirements, please ensure the waterproof cable sealing head. The following diagram:


 How to install to meet the requirements of IP67:

Please make sure that the sealing head is not damaged.

Please make sure that the cable is not damaged.

Please make sure that the cable for use with electrical connection specification.

Cable into the electrical interface before its curved downward, ensure that the water will not flow into the shell, see the

Tighten the cable seal head, see the

Please electrical interface will not use blind plug tight, see the
