Understand the applicable working conditions of 80G radar level gauge and tank side alarm

In the chemical pharmaceutical industry, working conditions are usually characterized by strong corrosiveness, flammability and explosiveness, easy crystallization, large pressure fluctuations, and extremely high hygiene requirements. The 80GHz radar level gauge is the preferred choice for these complex environments due to its non-contact measurement and strong penetration capabilities.

What are the main application conditions of radar level gauges in chemical pharmaceuticals?

1. Reactors

This is the most core and complex working condition in pharmaceutical technology.

Challenge: There are usually agitators and heating coils inside, and the liquid level may have foam, boiling or violent fluctuations.

Radar advantage: The 80G radar has an extremely narrow beam angle (usually 3 ^ circle sim 8 ^ circle), which can accurately avoid mixing blades and tank wall obstacles; At the same time, high-frequency signal can effectively penetrate slight foam.

2. Corrosive Storage Tanks for Highly Corrosive Media

Pharmaceuticals often involve strong acids (hydrochloric acid, sulfuric acid), strong bases, or strong solvents.

Challenge: Media can corrode metal sensors and shorten equipment lifespan.

Radar advantage: The antenna is fully encapsulated with PTFE (polytetrafluoroethylene) or PEEK material, which has strong chemical inertness and enables true non-contact measurement without worrying about corrosion.

3. High cleanliness/sterile environment (Hygiene/Sterile Tanks)

Pharmaceutical products or intermediates have strict hygiene requirements and must comply with GMP standards.

Challenge: Sensors must not have blind spots and must support CIP (In Place Cleaning) and SIP (In Place Sterilization).

Radar advantages: The flat antenna design leaves no dead corners for liquid accumulation, is resistant to high temperature steam, and fully meets the requirements of aseptic production.

4. Volatile&Toxic Solvent Tanks

Such as ethanol,pyroacetic spirit,methylbenzene, etc.

Challenge: Volatile gases can cause an increase in pressure inside the tank, and the medium is flammable and explosive.

Radar advantage: Penetration: Radar waves are not affected by vacuum, high pressure, or steam.

Explosion proof safety: intrinsically safe or explosion-proof design, combined with tank side alarm, can prevent the risk of tank overflow in real time and ensure the safety of on-site personnel.

5. Viscous&Crystallizing Media

Challenge: The medium easily adheres to the surface of the sensor.

Radar advantage: The 80G radar has concentrated energy and a certain ability to compensate for hanging materials. Even if there is a small amount of condensed water or attachment on the antenna, it can still penetrate through strong signals and obtain true liquid level reflection.

Nuoying suggests that in chemical pharmaceutical conditions, the installation position should be as far away as possible from the feed inlet (to prevent direct spraying of the antenna) and the mixing shaft. The combination of "80G radar+tank side alarm" is very suitable as a high-level safety interlock (HH alarm), providing a second level of safety protection outside the DCS system.
