JUMO multirange and differential pressure transmitter

For non-aggressive gases Basic type: 402006

The product enables differential pressure measurement in non-aggressive gases. Permanent overpressure protects the process from dust penetration. The transmitter is mainly used in cleanrooms.

Measuring range: 2.5 hPa to 100 hPa DP
Zero point adjustment possible
0(2) to 10 V or 0(4) to 20 mA

New product

JUMO SIRAS P21 DP

Process pressure transmitter with SIL/PL Basic type: 403024

The pressure transmitter reliably and accurately measures differential pressure of liquids, steam, and gases. It was developed for use in safety-related plants with Safety Integrity Level (SIL) according to DIN EN 61508. As a result, the transmitter is perfectly suited for safety measuring chains in the process industry and mechanical engineering.

Up to 100 bar
Linearity: 0.05 %
Safety Integrity Level (SIL 2/SIL 3), PL c/PL d

JUMO differential pressure monitor

For air, smoke, and exhaust gases Basic type: 404201

The type 4 ADS product acquires the negative pressure, overpressure, or differential pressure of air, smoke, and exhaust gases in ventilation, air-conditioning, and filter systems. It is suitable to switch a current circuit ON, OFF or change it over, when the actual value changes in relation to the setpoint value.

Temperature -15 to +70 °C
Parts made out of polycarbonate
Measuring ranges: from 0.4 mbar

JUMO MIDAS DP10

Differential pressure transmitter Basic type: 401050

The product acquires the differential pressure in liquid as well as gaseous media and transforms it into an analog output signal. The transmitter is mainly used for filter monitoring.

The most important background information

What are differential pressure sensors?

Differential pressure sensors measure the difference between 2 absolute pressures p1 and p2 in gases, steam, and liquids. Among other applications they can be found in filter monitoring, level measurement in closed containers, and safety-critical systems. They are often referred to as differential pressure transmitters or differential pressure transducers.

What are differential pressure sensors? - JUMO FAQ

How does a differential pressure transducer work?

A differential pressure sensor has 2 hermetically/air-tight sealed chambers, each with a process connection, which are separated from each other by a flexible membrane with a glued on resistance bridge. The process connections are connected in front of and behind a possible pressure reduction so that the pressures act on the membrane in the opposite direction. If the pressure in the chambers is the same, the membrane remains flat. When the pressure in one of the chambers decreases or increases, the membrane tilts towards the chamber with the lower pressure

What are the different types of differential pressure sensors?

A distinction is made between piezoresistive and capacitive measurement. Most differential pressure sensors are now based on the piezoresistive effect (the change in electrical resistance of a material caused by tension or pressure). This effect is achieved by metallic strain gauges, which are glued to the elastic membrane already mentioned, or by silicon wafers.
