Name: Endress+Hauser PMP75 Cerabar 0-2 barg – Manual & Price Quote
Brand: Endress+Hauser (E & H)

Description

Overview

The Endress+Hauser PMP75 Cerabar is a digital pressure transmitter with a metal diaphragm seal, and this configuration, order code PMP75-1QA1K11AR3DU, is factory-calibrated to a 0-2 barg low-pressure range. The PMP75 platform is specifically engineered for process and hygiene applications that combine a low measured pressure with extreme process temperature, from -70°C up to +400°C, conditions found in steam-sterilized vessels, autoclaves, and thermally cycled process lines where a standard ceramic-cell transmitter would be unsuitable.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the PMP75 Cerabar to pharmaceutical manufacturers, food and beverage plants, and process industries across the Sultanate of Oman, Muscat, and the wider GCC region. Specifying the PMP75 through Seven Star LLC comes with a formal quotation, the manufacturer datasheet and technical support with selection.

Measurement Principle

The PMP75 uses a metal diaphragm seal system in which the process pressure is transmitted through a fill fluid to an internal capacitive measuring cell, isolating the sensing element from direct contact with the process medium. The transmitter’s digital electronics convert the resulting capacitance change into a linearized 4-20mA signal proportional to pressure, with continuous temperature compensation applied to maintain accuracy across the calibrated 0-2 barg span despite large swings in process temperature.

Because the diaphragm seal isolates the measuring cell from the process, the PMP75 can be applied to hygienic, corrosive, or high-temperature media that would otherwise damage a directly wetted sensor, while quick setup with an adjustable measuring range allows the low 0-2 barg span to be precisely configured during commissioning. The device is designed according to IEC 61508 for use in SIL2/SIL3 safety applications, an important consideration where low-pressure excursions in sterile or thermally sensitive processes indicate a serious upset.

Engineering Design of the Endress+Hauser PMP75

The PMP75 uses a two-chamber transmitter housing available in aluminum or stainless steel (316L), the same rugged platform shared across the Cerabar S family, which physically separates the terminal compartment from the electronics compartment so that field wiring can be serviced without exposure to the measuring circuitry. The metal diaphragm seal and fill fluid are selected at the point of order to match hygienic, food-grade, or high-temperature process requirements, and the flush or extended diaphragm mounting keeps the sensor face clean in viscous or particulate-laden media.

A backlit local display with a four-key operating concept allows field engineers to configure the zero and span, apply damping, and read diagnostic information without a separate handheld communicator, while the HART-based 4-20mA output integrates directly with existing control loops. The PMP75’s tolerance for process temperatures up to +400°C makes it a common choice for steam-in-place (SIP) and clean-in-place (CIP) cycles common to hygienic processing.

Key Features

The Endress+Hauser PMP75 combines low-pressure sensitivity with extreme-temperature durability. Core capabilities include:

Factory-calibrated 0-2 barg low-pressure range suited to hygienic and thermally cycled process lines.
Metal diaphragm seal isolating the measuring cell from direct process contact.
Process temperature tolerance from -70°C up to +400°C, supporting steam-in-place and autoclave cycles.
Two-chamber aluminum or stainless steel (316L) housing isolating wiring from sensitive electronics.
Local backlit display with four-key configuration for on-site zero, span, and damping adjustment.
SIL2/SIL3-capable design per IEC 61508 for use in low-pressure process safety interlocks.
HART-compatible 4-20mA output for seamless integration with existing DCS and PLC platforms.
Flush and extended diaphragm mounting options for viscous or particulate-laden hygienic media.

Industrial Applications

The 0-2 barg range of this Endress+Hauser PMP75 configuration is widely specified for autoclave and sterilizer pressure monitoring, low-pressure steam jacket control, and CIP/SIP cycle verification in Oman’s pharmaceutical and food and beverage manufacturing facilities, where the combination of low pressure and high temperature rules out most conventional transmitters. The metal diaphragm seal also makes the Endress+Hauser PMP75 a strong fit for corrosive low-pressure gas blanketing applications in chemical processing, where a directly wetted ceramic cell would degrade quickly under repeated chemical exposure.

With engineering support in Muscat, Seven Star LLC supplies the Cerabar PMP75 to EPC contractors and plant operators throughout the Sohar and Salalah economic zones, supporting hygienic vessel pressure monitoring, reactor jacket control, and sterile process interlocks. Facility engineers across the region rely on Seven Star LLC for both the initial specification of the correct calibrated range and the long-term parts and calibration support that follows commissioning of the Endress+Hauser PMP75.

About brand

Level, flow and pressure measurement account for most of the Endress+Hauser instruments engineers ask us about, and each device is defined by the order code on its nameplate. Endress+Hauser, founded in 1953 and based in Reinach, Switzerland, builds process instrumentation for liquids, gases and bulk solids.

Seven Star LLC is an independent supplier listing Endress+Hauser (E+H) flowmeters, radar and vibronic level instruments, pressure and temperature transmitters and liquid analysis equipment for plants in Oman and the GCC.

Endress+Hauser product families on this page

Level is the largest group: Micropilot free-space radar (FMR10B, FMR62 and the FMR67 for bulk solids, all 80 GHz), Levelflex guided radar (FMP50, and the FMP55 for interface measurement), the Liquiphant FTL51 vibronic point level switch and the Prosonic S FMU90 ultrasonic transmitter. Flow covers Proline Promag electromagnetic flowmeters (Promag P 300, Promag W 400) and the Prowirl F 200 vortex meter. Pressure is represented by the Cerabar PMP51B, temperature by the iTEMP TMT82 HART transmitter. For liquid analysis the listing has the Liquiline CM444 multiparameter transmitter and Memosens sensors such as the CPS11E pH electrode.

Where Endress+Hauser instruments are used

Water and wastewater plants rely on Promag W meters, radar level and Liquiline analysis. Oil and gas, chemical and power plants specify Levelflex and Micropilot on tanks and separators, Prowirl on steam and gas, and Cerabar on process lines. Food and pharmaceutical producers use hygienic versions of the same families, and cement and mining sites use the FMR67 on silos.

Ordering Endress+Hauser instruments: what we need

Send the order code and, for a replacement, the serial number from the nameplate. The extended order code is better still, because it spells out every option. Without a code we need the medium, pressure and temperature, measuring span, process connection, wetted materials, output signal or fieldbus, power supply, display and the hazardous area approval required. For flowmeters add line size and liner, for radar the tank height and nozzle size.

Frequently Asked Questions

What makes the PMP75 suited to hygienic and high-temperature processes?

The PMP75 uses a metal diaphragm seal that isolates the measuring cell from the process and tolerates temperatures from -70°C up to +400°C, allowing it to survive steam-in-place and autoclave sterilization cycles that would damage a standard transmitter.

Why choose the 0-2 barg range for the PMP75?

The 0-2 barg range gives fine resolution for low-pressure duties such as autoclave monitoring, steam jacket control, and CIP/SIP verification, where a wider-range transmitter would lack the sensitivity to detect meaningful pressure changes.

What diaphragm and fill fluid options are available for the PMP75?

The PMP75 is available with flush or extended metal diaphragm seals and a choice of fill fluids selected at the point of order to match hygienic, food-grade, or high-temperature process requirements.

Can the PMP75 integrate with legacy 4-20mA control systems?

Yes. The PMP75 outputs a standard 4-20mA/HART signal, allowing it to integrate directly into existing analog loops as well as digital HART-based asset management systems without additional hardware.

Is Seven Star LLC an experienced supply partner for Endress+Hauser products?

Yes. Seven Star LLC supplies Endress+Hauser (E & H) products to customers in Oman and the GCC and can provide the manufacturer documentation and technical support on request.
