Case Study: WIKA Pressure Sensor With Diaphragm Seal Enables Breakthrough Filtration for Wastewater Treatment Customer
Patrick McGrath | PressureThe wastewater treatment equipment market was worth over $35 billion in 2015, and is expected to reach more than $55 billion by 2023. Increasing demands for water, alongside a trend in recycling and reusing this precious resource, are two reasons for the growth. …
Case Study: Ensuring Safety and Efficiency at a Geothermal Site with WIKA’s Pressure Measurement Technology
Hardy Orzikowski | PressureIn geothermal plants, transforming the earth’s heat into electricity imposes challenging conditions on pressure measurement equipment. WIKA’s pressure monitoring instruments and diaphragm seals can withstand harsh environments, as shown in a recent installation at …
ASME BPE Study Leads to New Recommendations to Help Prevent Process Contamination
Patrick McGrath | Applications, PressureWIKA inline diaphragm seals and flow-through thermowells either reduce or eliminate dead legs where bacterial or fungal contamination can develop in pharmaceutical manufacturing processes. Process engineers know for decades that “dead legs” in piping and …
Diaphragm Seal Pattern Matching Prevents Damage, Reduces Temperature Effects
Chi-Che Ma | PressureDiaphragm seals are a common accessory for pressure gauges and sensors in many refining and manufacturing applications. The pressure of the media being measured bends the flexible diaphragm slightly inward, and this movement displaces the fluid behind the seal into the …
