Pressure Measurement & Control
The Jumo dTrans p02 series of pressure transmitters, available from ASSTech Process Electronics & Instrumentation, combines tried and tested sensing systems with state-of-the-art digital technology. These are available in three models.
The Jumo dTrans p02 Delta pressure transmitter measures the differential pressure in both corrosive and non-corrosive gases, vapours and liquids.
The pressure transmitter uses the piezo-resistive effect to make the measurement. The output signal is a DC current which is linearly proportional to the input pressure. For through-flow measurements it is possible to set up the output signal to be proportional to the square root of the input pressure.
The pressure transmitter Type Jumo dTrans p02 is used to measure the gauge (relative) and absolute pressures of corrosive and non-corrosive gases, vapours and liquids. The measuring device for the pressure transmitter is a piezo-resistive element or thin-film strain gauge. The output signal is a proportional DC current which is linearly proportional to the input pressure.
In the version with Protection EEx ia IIC, the pressure transmitter can be mounted within the hazardous Zone 1, for connection to Zone 0. For special applications, like the measurement of highly viscous media for example, the Jumo dTrans p02 is available with flush pressure connections in various styles.
Suitable pressure connections are also available for applications involving media temperatures of up to 200°C.
The Jumo dTrans p02 Ceramic pressure transmitter measures the gauge (relative) or absolute pressure in both corrosive and non-corrosive gases, vapours and liquids. The ceramic-based measuring system in this pressure transmitter operates on the principle of capacitive measurement. The output signal is a DC current that is proportional to the input pressure.
The Jumo dTrans p02 pressure transmitter series can also be operated through a HART communicator, or a PC in conjunctions with a HART modem and the Jumo set-up program running under Windows.
