Differential Pressure Transmitter

Differential Pressure Transmitter
Model No: 891.34.2189

Differential pressure measuring ranges from 0 ... 160 mbar

High working pressure (static pressure): 25 bar

Overload value either side up to 25 bar

Solid case construction for protection against externalmechanical effects

Integrated pressure equalising valve (option)


The differential pressure transmitters DELTA-trans are particularly intended for the measurementof very low differential pressures with high demands on one-sided overload.

Standard output signals of 4 … 20 mA (2-wire system) or 0 … 20 mA (3-wire system) can be provided from a nonstabilised DC supply of 10 … 30 V.

Due to the solid and compact design of the instrument, the operation requires almost no maintenance even under arduous industrial service conditions.

As an option, the differential pressure transmitter DELTAtrans (in 2-wire design; 4 ... 20 mA) may be supplied with an integrated 3½-digit LCD-display.

Electrical connection is made by means of a cable box with cable gland M20 x 1.5.


Suitable for all gaseous and liquid media that will not obstruct the pressure system

Heating, ventilation, air-conditioning and dust removing technology

Technical building equipment, filter plants, drinking and service water treatment

Monitoring and control of pumps in pressure boosting and fire extinguishing plants
