## [Differential pressure in cleanrooms](/en-GB/solutions/differential-pressure-in-cleanrooms) ![Kimo Class 320 labs](/sites/default/files/entityone_paragraphs/images/SOLUTION_Intro_468x468_13.png) ## Preventing contamination To ensure the safety of people and products and prevent contamination, many sectors use controlled atmosphere zones maintained at positive or negative pressure with a differential of just a few Pascal (Pa). In cleanrooms, very small differences in pressure are used to regulate air circulation between different zones. Measuring these values is extremely delicate, as it must be done with precision, stability and durability. Sauermann benefits here from the 45 years of experience of its KIMO brand in this field. ## Parameters to be monitored - **Differential pressure** Continuous Monitoring ## Continuous Monitoring Measuring instruments in cleanrooms require a very high level of accuracy and stability to measure pressure differences in the range 10 to 30 Pa. This critical type of measurement can therefore only be ensured by using high quality sensors. Our new Class 320 pressure transducers guarantee accurate and stable measurement. Their accuracy of ±0.3 Pa and their programmable self-calibration system ensure long-term measurement reliability. Their IP66 waterproof housing is resistant to vaporised H202 and is specially designed for use in ZACs.

For installation in transmitters already delivered. Connector for external type K thermocouple probe (probe not included, please check our available models). The Si-PRO-DP modules for Si-C320 transmitters have a temperature compensation from -10 to 50°C (14 to 122°F) and an auto-calibration process that ensures an excellent stability and a perfect reliability of the measurement in both low as high range over time. Main applications: differential pressure monitoring in clean rooms, pharma/cosmetic and semiconductors manufacturing facilities, hospital isolation rooms, operating rooms and other critical environments. ![Kimo Class 320 labs](/sites/default/files/styles/max_1300x1300/public/images/SOLUTION_Produits01_Surveillance_699x393_5.png?itok=jdEu4dB9) Spot Measurements ## Spot Measurements To limit the spread of particles and micro-organisms, production areas are under positive pressure to prevent outside contaminants from entering. Conversely, containment areas are under negative pressure to prevent outside contamination. To maintain balanced pressure differentials, the distribution network must be precisely adjusted by measuring the supply and exhaust air flow rates and the air change rate. Our DBM 620 balometer and our various anemometers are perfectly suited to this type of measurement.
