JUMO dTRANS p31 Hygienic Pressure Transmitter
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.
As the official authorized partner and exclusive regional representative for JUMO, 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 shipped through Seven Star LLC is genuine JUMO product with full manufacturer warranty and access to local technical support – ensuring facility engineers and procurement teams in Muscat, Sohar, and Salalah receive an authentic, factory-certified JUMO dTRANS p31 backed by regional service.
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.
Key Features
The JUMO dTRANS p31 combines hygienic, dead-space-free construction with high-temperature measuring performance that makes it a standard choice for food, beverage, and pharmaceutical pressure measurement.
