Product Description

Product Description

Product Overview 

In the complex landscape of industrial measurement and control, the accurate determination of pressure in gases and liquids is of paramount importance. The E+H Gauge pressure Cerabar PMP11 pressure transducer, developed by the esteemed Endress+Hauser, stands as a testament to precision, reliability, and versatility in pressure measurement technology. This transducer has carved a niche for itself across a wide spectrum of industries, from manufacturing and processing to environmental monitoring and beyond, owing to its advanced features and robust performance capabilities.

 Working Principle

At the heart of the Cerabar PMP11 lies a high - quality metal sensor. This sensor operates on the principle of piezoresistivity. It consists of a metal diaphragm, typically made of materials like 316L stainless steel, which is highly resistant to corrosion and mechanical stress. When pressure is applied to the diaphragm, it deforms. This deformation causes a change in the resistance of piezoresistive elements that are integrated within or attached to the diaphragm.
The piezoresistive effect is based on the fact that the electrical resistance of certain materials changes when mechanical stress is applied. In the case of the PMP11's sensor, the change in resistance is proportional to the applied pressure. This change in resistance is then detected and measured by the transducer's internal circuitry. The metal sensor's design and construction ensure high sensitivity to pressure variations, allowing for accurate measurements even in applications where pressure changes are subtle.

Sensor Overpressure Protection

The metal sensor of the Cerabar PMP11 is engineered to withstand significant overpressure. The maximum overpressure limit is typically around 60 bar (900 psi). This overpressure protection feature is crucial in applications where sudden pressure surges can occur. For instance, in hydraulic systems during start - up or shutdown, there can be momentary spikes in pressure. Similarly, in pipelines, sudden valve closures or changes in flow rates can cause pressure surges. The ability of the sensor to withstand these overpressure events without damage ensures the long - term reliability and integrity of the transducer. It helps prevent costly sensor failures, system downtime, and potential safety hazards associated with inaccurate pressure measurement due to a damaged sensor.

Installation

The installation of the Cerabar PMP11 is relatively straightforward, thanks to its compact design and variety of process connection options. When installing the transducer, it is crucial to ensure that the process connection is properly made to prevent leaks. For threaded connections, appropriate thread sealants should be used according to the application requirements. The sealant should be compatible with the fluid being measured and the environmental conditions.

The transducer should be installed in a location where it can accurately measure the pressure of the target gas or liquid. It should be placed in a position that is representative of the pressure in the system and is not affected by local flow disturbances or pressure gradients. Additionally, the installation location should be easily accessible for maintenance and calibration purposes.
