About Longvista
Longvista Sagl is a company specialised in industrial automation, based in Caslano in the canton of Ticino. The company supplies custom-adapted process sensor technology (ultrasonic and capacitive level sensors, pressure and flow measurement), frequency inverters and ATEX-certified wireless IIoT components for predictive maintenance. Its core service is adaptation to customer-specific mechanical and electrical specifications: custom process connections (G-, NPT threads, flanges), special materials such as PVDF and stainless steel 316L, custom cable lengths and signal output configurations (4–20 mA, RS485, Modbus RTU). In small-series and prototype production, modified sensor housings, thread adapters, cable harnesses and process fittings are manufactured; specific turning and milling operations are coordinated. Every unit undergoes a signal, pressure or calibration test in Caslano before dispatch, including complete CE, RoHS and material test documentation. Customers include industries such as HVAC, water and wastewater engineering, food processing, energy supply, heavy machinery, shipping and chemicals in Switzerland, Germany and Italy.
