Hangzhou Yeli WZP-231 anti-corrosion temperature sensor full series

Features

1. A variety of anti-corrosion materials are available for users to choose from, which can be applied to various industrial sites with high anti-corrosion levels. According to the requirements of different working conditions, users can choose various core bodies of temperature transmitters such as ordinary assembled type, armored type, high temperature armored type, etc., with high measurement accuracy.

2. It adopts a waterproof or explosion-proof junction box with a protection grade of IP65. It can be used in the open air all day and has explosion-proof grade of dIIBT4~dIICT6.

3. It can be equipped with a temperature converter to convert the measured values into analog quantities such as 4~20mA or 1~5V to achieve long-distance transmission of measured values.

4. According to the requirements of different working conditions, users can choose various types of chips such as ordinary assembly, armored type, high temperature armored type, etc.

5. The anti-corrosion type of protective sleeve uses different materials to protect the pipe in direct contact with corrosive which can protect the temperature-sensing element from corrosion and resist strong acid and alkali corrosion of the thermal resistor/coupler, thereby enabling accurate measurement.

6. The independent armored anti-corrosion type uses armor wire with anti-corrosion properties or performs anti-corrosion treatment on the armor material to meet the requirements of corrosion resistance.
