Sensors for Liquids and Gases
The large range of fluid sensors provides you with high-performance pressure, temperature, flow and fill-level sensors for use in systems and machines. The sensors are designed on the basis of a modular platform in order to match them to customer-specific requirements.
Process Monitoring for Full Transparency
Continuous monitoring and analysis of production processes are required in order to assure top product quality. Fluid sensors acquire all relevant process values in real-time and detect even the smallest deviations, so that you can respond quickly to changing conditions. Make your processes transparent and use this valuable information in order to optimize sequences and conserve resources. This results in increased efficiency and productivity, and secures your competitive advantage.

Smart Communication with IO-Link Sensors
wenglor fluid sensors are already plunging into digital processes today. And they use the most up-to-date communication standard via IO-Link. IO-Link sensors communicate with all common control systems via the manufacturer-independent interface and can thus be easily integrated into existing networks. You profit in many ways:
- Simplified operation
- Faster initial start-up
- Increased system availability
- Reduced maintenance costs
Gran facilidad de manejo
El software gratuito wTeach2 de wenglor permite configurar fácilmente los sensores de fluido con IO-Link. Los puntos de conmutación también se pueden ajustar mediante gráficos de forma clara y sencilla con un solo clic.
Rápida puesta en marcha
Los ajustes de los sensores se almacenan en la unidad de control y se transfieren automáticamente a otros sensores de modo que, una vez están ajustados, se pueden duplicar las veces que sea necesario.
Optimización de los procesos
Los sensores de fluidos con IO-Link generan y envían datos adicionales de diagnóstico y estado para la monitorización de este. Mediante el software wTeach2 se pueden analizar estos datos para proporcionar información sobre un mantenimiento orientado a las necesidades y evitar así paradas no deseadas.
Plug & Play con Data Storage
Cuando se sustituye un sensor, los parámetros guardados se transfieren automáticamente al sensor nuevo, lo que permite que el cambio se produzca sin necesidad de programarlo.
