JUMO dTRANS p20 DELTA Differential Pressure Transmitter with HART, Type 403022

Name: JUMO dTRANS p20 DELTA DP Transmitter 403022 | Seven Star LLC
Brand: JUMO
SKU: dTRANS p20 DELTA

Description

A differential pressure transmitter for flow, filter and level duty with HART and optional SIL2

The JUMO dTRANS p20 DELTA (type 403022) measures differential pressure of gases, steam and liquids with a silicon sensor behind stainless steel separating diaphragms. It offers a 4 to 20 mA two-wire output, optionally with HART 7, an integrated two-line LCD with bar graph, and a rotary knob for on-site operation. The datasheet states linearity down to 0.07 % and a turndown of up to 400:1 on the -1 to +1 bar range. A version with ATEX Ex ia protection allows installation up to zone 0, and a SIL version evaluated by exida according to IEC 61508 is suitable for monitoring process level and pressure up to SIL2. Diaphragm seals can be fitted for hygienic or aggressive processes.

Housings, options and ordering restrictions

Three housings are offered: a short stainless steel case with M12 plug connection (type 1), a long stainless steel case with cable fitting (type 2) and a precision-cast case with an M20 cable fitting (type 3). Process connections are two 1/4-18 NPT connections to DIN EN 837 or a screwed diaphragm-seal version, with wetted material in stainless steel, tantalum or NiMo and either silicone oil or halogenated oil for oxygen service as the filling medium. Extra codes add UKEX (085), customer-specific factory settings (100), oil and grease free (624), mounting brackets for 2 inch pipe (633), a TAG number (634), a NACE declaration (635), expanded ambient temperature (681) and PN 420 (694).

The datasheet lists limits: the SIL version needs output 410 and the display, and is not available with the 10 mbar range, a diaphragm-seal connection or extra code 681. The Ex ia version needs output 410 and is not available with the plastic cable fitting or plastic cover. The 10 mbar and 1 bar bipolar ranges are only available with stainless steel process connection material.

Setup, accessories and companions

Besides the knob, the device is set up with the JUMO dTRANS p20 setup program (00537577) over a USB/TTL interface cable (00456352), with a HART modem (00443447), or with the DTM from data sheet 403025 (00738288). Other accessories include M12 line sockets of 2 m (00404585 straight, 00409334 angled), a mounting bracket (00543777), an Ex-i repeater power supply (00577948) and on-site calibration including DAkkS (00758363). Valve blocks and diaphragm seals are described in data sheets 409706 and 409772 to 409786.

Display scaling, a linear or square-root characteristic for flow measurement and a current-generator function support commissioning.

Choosing a temperature sensor starts with the range and accuracy. A Pt100 RTD is accurate and stable from about -200 to 600 °C and is the usual choice in process plants. A thermocouple (type K or J, for example) covers much higher temperatures and responds faster but is less accurate. The wiring also matters: a 3-wire or 4-wire Pt100 connection cancels the resistance of the cable, while a 2-wire connection adds an error that grows with cable length. That is why a head-mounted transmitter is often fitted close to the sensor.

Where JUMO products are used

In Oman and the GCC, JUMO sensors and controllers are used in oil and gas and chemical plants, food and beverage production, plastics and metal heat treatment, HVAC and district cooling, water and wastewater treatment, swimming pools and marine applications.

Ordering JUMO products: what we need

Send the JUMO type number and the full order code from the label (for example 902020/10-...). For probes, add the sensor type (Pt100, Pt1000, type K or J), the number of wires, the insertion length and diameter, and the process connection. For controllers, add the input, outputs and supply voltage.
