DE90 Digital differenstryktransmitter

Differential Pressure Transmitter DE90

The DE90 differential pressure transmitter from Fischer stands out, among other things, by a large 4-line display with bar graph, a wide measuring range and simple operation and parameter setting – as well as many application possibilities, the display has a changing background color that indicates the process status relative to configured limit values

The new Fischer DE90 transmitter is a multifunction differential pressure transmitter and is, among other things, very well suited for monitoring supply and exhaust air in filtration and extraction systems

Flexible and precise differential pressure transmitter with high accuracy

The Fischer DE90 is a flexible and precise differential pressure transmitter that measures accurately and has a wide measuring range (from 25 Pa to 25 kPa), the transmitter can be expanded with sensors for measuring temperature, relative humidity and air quality, which, among other things, makes it possible to perform temperature compensation for supply and exhaust air when measuring volumetric flow, analog outputs (current/voltage) as well as up to four switching outputs for control, optional Modbus RTU interface

Many advantages with a DE90 differential pressure transmitter

With a DE90 transmitter from Fischer you get, among other things, the following advantages

• Controlled measurement of volumetric flow to reduce costs
• Dynamic filter monitoring makes it possible to detect potential filter blockages in time
• Individual control of facilities in Clean Rooms and safety laboratories
• Can be integrated into Clean Room panels and control centers

The Fischer DE90 also has the advantage that it can be used in ATEX zones (2 and 22) and is approved for safety-critical applications
