Successful Application of Jiwei High Temperature Vibrating Rod Level Switch in PET Particle Measurement

Recently, in the production process of polyester spunbonded hot-rolled material in a Foshan factory, Jiwei high temperature type Tube-11 Vibrating Rod Level Switches are successfully applied in the level measurement of polyester chips (mainly referring to PET).

Difficulties in PET Particle Measurement at Drying Tower

Due to the high temperature in the whole production process of polyester spunbonded hot-rolled material, the requirements for measuring instruments are more stringent:

1. Instrument probes are required to withstand high temperature of 170℃.

2. The protection level of instrument should reach IP66/IP67 to ensure stable operation.

3. Because of the strong water-absorbing quality and fine granularity of PET Particle, material hanging problem on instrument probe tend to occur, so the strong anti-hanging function of instrument probe is also required.

Characteristics of High Temperature Type Tube-11 Vibrating Rod Level Switch

Tube-11 is the first made-in-China Vibrating Rod Level Switch that designed with double vibration tubes, the ideal rod design ensures a reliable function in solid applications with the lowest measurable density of 0.02g/cm³.

In addition to the above features, Jiwei high temperature type Tube-11 has the additional advantages:

1. Strong anti-hanging and non-adhesive ability, high reliability to viscous and easy-hanging medium.

2. Process temperature can reach up to 250℃, and for ultra-high temperature (Water/air cooling) type is 400℃, which is industry-leading.

3. The protection level reaches IP66/IP67.

4. Gas and dust explosion-proof, universally applicable ( Flame-proof: Ex d IIC T6 Gb, Ex tD A21 IP66 T80℃; Intrinsic Safe：Ex ia IIC T6 Ga, Ex iaD 20 T85℃).

Jiwei high temperature type Tube-11 Vibrating Rod Level Switch has advanced performance index and high cost performance ratio, so the client chooses Jiwei Tube-11 to replace imported products for measuring the level of polyester chip (PET) in the production process of polyester spunbonded hot-rolled material.
