Differential pressure transmitter - special measuring range for particular low-pressure applications (Pa)

February 2017 - For room pressure monitoring (e.g. in clean rooms) FISCHER additionally offers differential pressure transmitters DE23 and DE46 with a measuring range from -20...+80 Pa.

In the past, measuring ranges have been unidirectional, designed for overpressure or negative pressure or larger measuring ranges with lower resolution (for example 0...+100 Pa respectively -100...+100 Pa). The bidirectional measuring range enables safe detection of flow reversal. The measuring range in overpressure enables application in all clean room classes with several pressure levels and the relatively small basic pressure range provides high measuring accuracy.

All sensors of the model range DE23 and DE46 are characterized by long-time stability as well as a very good reproducibility of measuring results.

New certificates are available – DS21 and NK10

May 2016 - Our FISCHER-devices are implemented also for safety relevant applications. On our homepage you will find, from now on, the available certificates. Our measuring instruments can be used as flow and level guard and as flow controller, -limiter.

The DS21 Differential Pressure Measuring and Switching Device is implemented as flow guard in heat transfer oil systems in compliance with DIN 4754-2:2015-03 and hot water systems according to VdTÜV Information sheet “Flow 100“.

A further example for the DS21 is the application as flow limiter according to DIN EN 12952-11:2007-09 and DIN EN 12953-9:2007-09 in water tube boilers and system components (steam boiler plants).

The NK10 Level Controlller will is used as level guard in heat transfer oil systems in compliance with DIN 4754-3:2015-3.

DE44 LCD - 2 channel differential pressure switch / transmitter

December 2015 - 2 channel differential pressure switch / transmitter with LCD color change display is as of this date available for both channels with root extracted characteristic curve, thus meeting the requirements of a multifunctional unit. Two switch contacts, one display as well as various analog outputs are already integrated as an option. The second root extracted characteristic curve serves to record volume flows at different measuring points with simultaneously differently dimensioned measuring ranges , such as supply air, exhaust air or combined for both measuring points. The unit is therefore interesting for applications in the field of energy management as the different features contained in one instrument help to reduce assembly and installation costs.
