Applications for Electroceramic Sensors
Morgan Electro Ceramics range of custom designed sensors find applications in many markets in particular Medical, Industrial and Aerospace. Key applications include level, flow, vibration and dynamic pressure measurement. The sensing principals used in Morgan sensors are either acoustic (active) and piezoelectric (passive)
Electronics form a key part of every sensor and Morgan Electro Ceramics offer sensors comprising of the sensing element only or design incorporating a level of electronics integration. Electronics design and manufacture is done in co-operation with our partner companies which include APEX in the USA and others in Europe.
Designing a drive circuit to match transducer characteristics is critical for good system performance. Morgan’s transducers are fully tested to ensure consistent electrical and mechanical characteristics to ensure good compatibility with our customer’s drive circuits.
Ultrasound Sensors use either time of flight measurement, doppler or acoustic transmission principles to measure a wide range of parameters.
• Level sensors
• Flow sensors
• Air in line sensors / bubble detectors
• NDT sensors
Morgan Electro Ceramics considerable expertise in key technologies for ultrasonic sensors is used to design custom sensors for OEM applications. Examples range for fuel level sensors for Boeing aircraft and probes for patient monitoring.
Morgan Electro Ceramics Engineers have expert knowledge of the fundamentals such as acoustics, matching layers, damping and adhesive technology which are all key to good transducer design.
A large portfolio of materials are used to design the optimum sensor in terms of acoustics, electro-mechanical properties and environmental resistance.
Designing a drive circuit to match transducer characteristics is critical for good system performance. Morgan Electro Ceramics transducers are fully tested to ensure consistent electrical and mechanical characteristics to ensure good compatibility with our customer’s drive circuits.
Morgan Electro Ceramics stable and high sensitivity materials form an excellent basis of accelerometers. The piezo electric materials can be used in either compression or shear mode to form single or multi-axis accelerometers. Accelerometers can be housed in standard housing (e.g. transistor cans) or custom made packages.
Morgan Electro Ceramics bimorph materials can also be used where increased sensitivity is required.
Arterial Pressure Transducer
Piezoelectric technology provides ultrasensitive readings
The Arterial Pressure Transducer (APT) is a piezoelectric transducer that provides fast, accurate blood pressure readings. Like all of Morgan Electro Ceramics’ ultrasonic transducers, it has been designed using our world leading piezo materials. These materials have extremely good electrical loss properties, high coupling and excellent mechanical properties.
We design our transducers using in-house modeling software backed by extensive test and measurement capabilities, including laser vibrometry for displacement measurement. All of Morgan Electro Ceramics’ transducer solutions are designed and manufactured to meet the requirements of customer specifications, for reliable performance in the most demanding environments.
The APT’s 1.25” diameter probe has a resonant frequency of 1.8khz, capacitance of 2000pf, and an output of 3 volts/Newton. It can be used with blood pressure cuffs, works well as a microphone, and comes with a shielded cable. It is available in O.E.M. quantities from stock.
A leader in piezoelectric technology
Morgan Electro Ceramics is a subsidiary of the Morgan Crucible Group Plc and forms part of the Morgan Technical Ceramics division. Morgan Electro Ceramics is a world leader in the design and manufacture of piezo components used in medical electronics applications, including:
• gas and liquid flow sensors
• doppler probes for fetal monitoring
• air in-line sensors
• actuators for miniature pumps

Wheel Balancing Sensors
Morgan Electro Ceramics’ over-moulded sensors for wheel balancing can be found in many garage workshops around the world. Many OEM manufactures of wheel balancing equipment have found that Morgan Electro Ceramics design offers and excellent solution in terms of value for money, robustness and accuracy. These over-moulded sensors are available in a number of versions. Transducers are generally supplied with exposed (solderable) connectors. Upon request custom versions with either IDC or flying leads (with or with out connector) can be manufactured.
As well as over-moulded designs Morgan Electro Ceramics also offers custom solutions using other housing methods to specific customer requirements.
Impact sensors use the piezo-electric effect to sense forces (dynamic) and rate of force application. Example applications of impact sensors are coin validation equipment and firmness testing (e.g. fruit). In designing these sensors great care is taken to ensure that the signal response is consistent in a variety of conditions, angle of impact, temperature etc. Morgan Electro Ceramics Engineers are able to design custom sensors meeting all your requirements.
