New range of sensors for fluid engineering

December 2013 Sensors & Transducers

Wenglor has introduced a state-of-the-art sensor range dedicated to fluid engineering. Based on a patented process which is unique in the field of flow sensor technology, it allows the WenglorFluid devices to be mounted regardless of position and flow direction while still providing precision measurements.

Extremely user-friendly due to their uniform design and ease of operation and connection, the WenglorFluid sensors’ watertight plastic and stainless steel housings ensure accurate performance. The large 7-segment display provides for easy, intuitive operation. The separate LED allows for quick recognition of the switching status.

All the sensors have a switching output which can be configured as either normally closed (NC) or normally open (NO) via the menu. If required they can be additionally equipped with an analogue current or voltage output. The range consists of UniFlow flow sensors, UniBar pressure sensors and UniTemp temperature sensors.

The UniFlow sensors ascertain the flow velocities of oily and aqueous media in closed piping systems. They do not have to be aligned to the direction of flow during installation. Even if the sensor is turned around, the switching point does not have to be readjusted. In addition, the UniFlow sensors can be mounted either parallel or perpendicular to the pipe for maximum flexibility.

The UniBar pressure sensors measure the relative pressure of any medium in closed systems within a range of -1 to +600 bar. Wenglor pressure sensors with metallic membranes are well suited for areas with strict hygiene requirements, such as in food and pharmaceutical applications. They are flush-mounted and therefore compatible with pipe cleaning devices.

The UniTemp temperature sensors measure the temperature of liquids and gaseous media and make it possible to monitor temperature within processes. They can be used under greatly varying ambient conditions as the switching points can be individually adjusted within a measuring range of 0 to 200ºC.
