Description:

The differential pressure transmitter, type JUMO dTRANS p20 DELTA with HART® interface, combines highest precision and easy operation.
It serves to measure the differential pressure of gases, vapors and fluids. The integrated LCD displays measured values and device data.
In the version with explosion protection “Ex ia (intrinsically safe)“, the pressure transmitter can be installed in zones up to ‘zone 0’ classification.
Case and probes are made of high-quality stainless steel.
It is also possible to connect diaphragm seals for special applications (see data sheets 40.9772 to 40.9784).
The transmitter is programmable and, thus, flexibly adaptable to versatile measuring tasks.
A comfortable setup program is available as accessories for operation via the interfaces.
The manual operation on site is very comfortably and quickly possible via a rotary knob.

Version with explosion protection “Ex d”, see data sheet 40.3023.
Version for relative and absolute pressure, see data sheet 40.3025.

Customer benefits

• Process safe and reliable: The parts coming into contact with the medium are made of stainless steel (optionally made of Hastelloy , Monel, titanium or PTFE coated with the use of a diaphragm seal) offer an optimum resistance even with aggressive medium. The measuring instrument is very precise (characteristic line deviation of 0.05 %) and offers a high long-term stability of <0.1 % per year. In the version with explosion protection “Ex ia (intrinsically safe)”, the pressure transmitter can be installed up to zone 0.
• Uncomplicated and time-saving: The measuring instrument can be set reliably and easily via a rotary knob on the device or via a comfortable setup program. The device is equipped with HART interface as well as the JUMO interface. Operation via the rotary knob is carried out from the outside without the necessity to open the device.
• Flexible: The measuring instrument can be aligned in any installation position for optimum legibility, configuration and electrical installation. The measuring features can be adapted to all important applications (process pressure, filling level, throughflow) and ambient conditions via the adjustable parameters.
