JUMO dTRANS p31 Hygienic Pressure Transmitter

Name: JUMO dTRANS p31 Hygienic Pressure Transmitter – Datasheet
Brand: JUMO

Description

Overview

JUMO dTRANS p31 is a hygienic pressure transmitter for increased medium temperatures, engineered to measure the relative or absolute pressure of liquid and gaseous media in food, beverage, and pharmaceutical process environments. Made entirely of stainless steel with a dead-space-free, easy-clean design, the JUMO dTRANS p31 combines a piezoresistive high-temperature measuring cell with a wide range of hygienic process connections, supporting a permanently high or strongly fluctuating medium temperature between -30°C and +200°C.

Backed by manufacturer datasheet documentation, Seven Star LLC proudly supplies the JUMO dTRANS p31 hygienic pressure transmitter to food, beverage, pharmaceutical, and process customers across Oman and the wider GCC. Every unit supplied through Seven Star LLC comes with manufacturer documentation and access to local technical support – supporting facility engineers and procurement teams in Muscat, Sohar, and Salalah who specify the JUMO dTRANS p31.

Working Principle

The JUMO dTRANS p31 uses a piezoresistive high-temperature measuring cell to detect process pressure, converting the mechanical deflection of the sensing diaphragm into an electrical signal proportional to pressure. Because the measuring cell is specifically engineered for high-temperature stability, the transmitter maintains its high overload resistance and longevity even when the process medium runs continuously hot or cycles frequently between temperature extremes – a common condition in CIP (clean-in-place) and SIP (sterilize-in-place) cycles found throughout food, beverage, and pharmaceutical processing.

A key design detail of the JUMO dTRANS p31 is its dead-zone-free configuration: all wetted components are stainless steel, and the front-flush sensing element eliminates crevices or pockets where product residue could collect and support microbial growth, directly supporting hygienic process safety and cleaning validation requirements. A large number of process connections allow the choice between a fully welded, seal-free system or a screw-connected system with seals, while remaining modular with respect to process connection adapters through the JUMO PEKA type 40.9711 quick-connection system.

Engineering Design of the JUMO dTRANS p31

The JUMO dTRANS p31 covers measuring ranges from 1 to 60 bar relative or absolute pressure, with accuracy (linearity) of 0.2 to 0.5%, and an optional raised-linearity variant achieving ≤0.2% of end value for applications demanding tighter measurement tolerance. Output signal options span 4 to 20 mA two-wire, 0(4) to 20 mA three-wire, DC 0.5 to 4.5 V three-wire, DC 0 to 10 V three-wire, and DC 1 to 5(6) V three-wire, giving engineers flexibility to match the transmitter to a wide range of control system input types.

Process connections include thread, hygienic fittings, JUMO PEKA quick-connections, and diaphragm seal assemblies, with special surface roughness values available on request for particularly demanding hygienic specifications. Protection types up to IP65/IP67 are achievable depending on the electrical connection selected, and an optional cast enclosure version provides additional mechanical protection where the transmitter is exposed to impact or harsh washdown conditions.

About brand

JUMO is the German maker of temperature sensors, process controllers, pressure transmitters and liquid analysis instruments. Moritz Kurt Juchheim founded it in Fulda in 1948 as M. K. Juchheim KG, making glass thermometers with six employees. The name JUMO comes from the founder's name. It is still a family company headquartered in Fulda, and the parent company has been called JUMO GmbH & Co. KG since 2003.

Seven Star LLC is an independent supplier in Muscat. We list JUMO RTD and thermocouple probes, thermowells, transmitters, controllers, recorders and water analysis instruments, and supply them to process plants, OEMs, HVAC contractors and water utilities in Oman and the GCC by type number.

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.
