JUMO MIDAS S05 OEM Pressure Transmitter
Overview
JUMO MIDAS S05 is an OEM pressure transmitter engineered for universal applications, acquiring both relative and absolute pressure with a fully welded, seal-free measuring system suited to almost any process medium. Built around a piezoresistive silicon sensor with a stainless steel separating membrane, the JUMO MIDAS S05 is highly resistant to overload even in the lowest measuring ranges and is rated for millions of pressure cycles, making it a proven choice for HVAC, refrigeration, compressor construction, and general machine and plant engineering.
As the official authorized partner and exclusive regional representative for JUMO, Seven Star LLC proudly supplies the JUMO MIDAS S05 pressure transmitter to industrial, OEM, and HVAC 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 MIDAS S05 backed by regional service.
Working Principle
The JUMO MIDAS S05 measures pressure using a piezoresistive silicon sensor mounted behind a stainless steel separating membrane in a fully welded measuring system with no elastomeric seals in the pressure path. As process pressure deflects the membrane, the resulting mechanical strain changes the electrical resistance of the silicon sensing elements, and onboard electronics condition this signal into a linear, calibrated output proportional to pressure. Because the measuring system is entirely welded rather than gasket-sealed, the JUMO MIDAS S05 offers optimum protection against process medium leakage, a critical advantage in HVAC, refrigeration, and hydrogen-related applications.
This all-welded silicon sensor architecture gives the JUMO MIDAS S05 its defining reliability advantage: the sensor withstands extreme overload conditions even at the lowest measuring ranges, and its digital compensation and calibration process during fully automated manufacturing ensures consistent, repeatable accuracy across production runs. A high degree of automation in sensor module calibration reduces both production time and manufacturing cost, translating into a competitively priced, field-proven OEM pressure transmitter.
Engineering Design of the JUMO MIDAS S05
The JUMO MIDAS S05 covers measuring ranges from 0 to 1 bar up to 0 to 100 bar relative pressure, and up to 0 to 40 bar absolute pressure, with accuracy (linearity) of 0.2 to 0.3%. The modular design offers a wide selection of process connections, including G ¼, G ½, ¼-18 NPT, and 7/16-20 UNF with valve seating, alongside electrical connection options such as the DIN EN 175301-803 form A connector and the M12x1 circular plug, with output signals of 4 to 20 mA two-wire or DC 0 to 10 V three-wire.
The transmitter operates across a medium temperature range of -40°C to +125°C, with electrical connection components similarly rated to withstand this range, and the compact, modular structure minimizes installation effort in OEM assembly lines. Beyond conventional HVAC and refrigeration duty, the JUMO MIDAS S05 is also suitable for hydrogen applications in electrolyzers, synthesis plants, and mobile fuel cells, reflecting the growing use of this transmitter platform in emerging clean energy equipment.
