The FISCHER ECO-LINE® – The new differential-pressure transmitter DE80

May 2021 – In addition to the high-quality FISCHER PRO-LINE®, the FISCHER ECO-LINE® has now been developed. The new DE80 differential-pressure transmitter is available in 2-wire technology, 3-wire technology and as a Modbus RTU variant.

The differential pressure transmitter from the FISCHER ECO-LINE® is robust, safe against overpressure, maintenance-free and suitable for neutral gas media. Typical areas of application are technical building equipment, clean room technology, filter monitoring, volume flow measurement, the control of frequency inverters, the measurement and monitoring of overpressure, negative pressure and differential pressure.

The measuring ranges for this differential pressure transmitter are between 25 Pa and 25 kPa or 0.25 mbar to 250 mbar. A possible offset correction can be made via a zero point button in the DE80 . Each basic measuring range can be spread into seven predefined measuring ranges via a DIP switch. In the basic measuring range, the maximum measuring error (linearity, hysteresis and non-repeatability) is 1.5%.

In addition to the switchable analogue output 0/4 ... 20 mA or 0/2 ... 10 V, the 3-wire version has an optional fully graphic LC display and an optional changeover contact. The 2-wire version has a current loop 4 ... 20 mA and optionally a fully graphic LC display. The Modbus RTU version has an optional full-graphic LC display.

FISCHER PRO-LINE® FT90 Humidity and Temperature Measuring Instrument

July 2020 - The FT90 a part of the FISCHER PRO-LINE® is a humidity and temperature measuring instrument with optional (differential) pressure measurement. The device is suitable for measurement in neutral gases and can be used in hazardous areas – zone 2 and 22 -. The FT90 can be used in many different ways, typical applications include for e.g. room and clean room monitoring, supply and exhaust air systems, filter monitoring, volume flow measurement and process monitoring.

The device is robust and maintenance-free. The handling is easy and offers many features. You will find detailed information in our data sheet. Of course our expert advisors are also available to answer your questions at any time.

Another device from the FISCHER PRO-LINE® is the DE90 with integrated filter monitoring. In our Animation DE90 animation DE90 you can get an overview of the new generation.


Effects of the coronavirus on the delivery situation of our products

New Animation - DE90 Digital Differential Pressure Transmitter

May 2020 - The integrated filter monitoring of the FISCHER DE90 makes it possible to securely determine the degree of contamination of the filter at any operating point now. It is now possible, to dispose contaminated filters saftey planned and enviromentally friendly . Undesired interruptions of operations can be mostly avoided.

Our new animation summarises interesting information for you.

Dynamic filter monitoring now also directly possible with the differential pressure transmitter – FISCHER PRO-LINE®

September 2019 - A highlight of the DE90 is the integrated dynamic filter monitoring. This makes it possible to monitor the filters of demand-controlled ventilation systems over the entire operating range and to display the actual filter contamination.

This type of monitoring can lead to considerable savings in energy costs, filter costs and unscheduled downtimes. In addition, the function of dynamic filter monitoring in connection with comprehensive data logging is also available with the universal measured value indicator and data logger EA15.

Differential Pressure Transmitter DE49 for Ex Applications Extended

August 2019 - Due to the demand especially in hazardous areas of Ex zones 1, 2, 21 and 22, the measuring ranges of the DE49 series in the low-pressure range have been extended. From now on, devices for the measuring ranges ± 25 Pa to ± 250 Pa are also available. The measuring range – 20 ... + 80 Pa, which is used in particular for monitoring clean rooms, should also be highlighted.

Due to the bidirectional measuring range, a flow reversal can be reliably detected. The DE49 differential pressure transmitter thus rounds off the application range of the DE23 and DE46 series, which are also designed for low-pressure applications.


March 2019 – New technical flyer!

Digital 2-channel differential pressure transmitter DE43 for explosion-hazardous applications

February 2019 - For connection up to MODBUS-compatible automation systems, the 2-channel transmitter DE43 is now available for EX zones 2 and 22. The unit is typically used for technical air-conditioning, ventilation and surface applications.

Two process connections can be supplied (standard and with 90° angle rotation). Measurement ranges extend from 4 up to ± 16 mbar max.

As an optional feature the unit can also be supplied with 2 digital inputs for connection up to proximity switches. Additional querying is thus possible for these signals via the RS485 interface and the MODBUS RTU protocol from the overriding control system.

SPECIAL SALE for portable measuring instruments until 30th September 2018

June 2018 - For our pressure hand-held gauge we have a summer special for you. The measuring instruments serve for field measurement of pressure, negative pressure and differential pressure in non-aggressive media.

The MA25 is available in two executions in the following measuring ranges: 0-200 mbar and 0-2 bar. The gross price was reduced for you from 471,00 Euros to 229.00 Euros. The MA31 features seven measuring ranges and was reduced from 769.00 Euros to 349.00 Euros. Our offer is valid until the end of September.

Application areas are versatile. The measuring instruments are for example applied for filter monitoring of air conditioners, service works at gas burners and in heating systems or for other inspection of industrial processes. Moreover, the devices are also frequently applied in the automotive sector.
