JUMO MIDAS S05 OEM Pressure Transmitter

Name: JUMO MIDAS S05 Pressure Transmitter – Datasheet & Quote
Brand: JUMO

Description

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.

With engineering support in Muscat, Seven Star LLC supplies the JUMO MIDAS S05 pressure transmitter to industrial, OEM, and HVAC 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 MIDAS S05.

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.

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.
