Special sensors
We offer a variety of special sensors for challenging embedded applications, like rocket motors, bridges, and the human body.
All special sensors have been developed through R&D efforts with our partners.
Dual bond stress & temperature sensor (DBST)
APPLICATION
- SOLID ROCKET MOTORS
- RUBBER/METAL INTERFACES
- CFRP/GFRP/METAL INTERFACES
FUNCTION
- MEASURES NORMAL OR SHEAR STRESS AND TEMPERATURE AT INTERFACE/BONDLINE
- ALLOWS NON-DESTRUCTIVE MONITORING OF THE BOND
- ALLOWS NON-DESTRUCTIVE PROPELLANT AGE DETERMINATION
DBST
Pressure: Standard, calibrated bond stress range: +/- 700 kPa (7 bar) / +/- 100 PSI, traction and compression
Sensitivity: 3 mV / bar; 20 mV / 100 PSI
Overpressure: 4 x standard full scale without changes
Maximum over-range without failure: 30 x standard full scale
Non-standard: the sensor can be customized to measure higher pressure or traction.
Temperature: 0.56 mV / °C; 1 mV / °F
Input: 1 mA – 4 mA constant current
Safety: Fail Safe, does not ignite propellant, intrinsically fused. In use at many solid rocket motor manufacturers.

Bore strain/diameter sensor
APPLICATION
- SOLID ROCKET MOTORS
FUNCTION
- MEASURES THE BORE DIAMETER OF A ROCKET MOTOR IN-SITU AND ITS VARIATION WITH TEMPERATURE
- MEASURES CHANGES AND EVOLUTION OF CHARGE SHAPE, DETECTS CREEP/SLUMP
- ALLOWS BORE CRACK DETECTION
Smart Pipe
APPLICATION
- CONDITION BASED MAINTENANCE OF PIPELINE WITH EXTERNAL DEVICES
- INTERNAL FLUID PRESSURE SENSING WITHOUT PRESSURE SENSOR
- DATA IS INTEGRATED IN A DIGITAL TWIN PIPELINE AT A DATA CENTRE
ADVANTAGES/FUNCTIONS
- NO HOLE THROUGH THE PIPE, NO SEAL, INTRINSIC ZERO LEAKAGE
- NO LINE INTERRUPTION DURING INSTALLATION
- WIRELESS DATA ACQUISITION
- CONTINUOUS PRESSURE MONITORING ANYWERE ON THE LINE
- SENSING POINTS CAN BE RECONFIGURED DURING SERVICE LIFE

Embedded rebar sensors for reinforced concrete
APPLICATION
- CRITICAL CIVIL ENGINEERING STRUCTURES (e.g. BRIDGES)
- INTEGRATED INTO REBAR STRUCTURES BEFORE THEY ARE EMBEDDED IN CONCRETE
FUNCTION
- MEASURES THE FORCE LOAD ACTING ON THE REBAR SEGMENT
- DETECTS STRUCTURAL STIFFNESS DEGRADATION
Haptic surface
APPLICATION
- FLEXIBLE MEMBRANES
- 2D HAPTIC DEVICES/TOUCHPADS
- ROBOTIC COMPONENTS SUCH AS FINGERS, HANDS, FEET
- ARTIFICIAL SKIN OF ANDROIDS / ZOIDS (ANIMAL ROBOTS)
FUNCTION
- INTEGRATES DEFORMATION AND TEMPERATURE SENSORS ON A FLEXIBLE MEMBRANE
Flow sensors
APPLICATION
- FLUID FLOW MEASUREMENT (IN PIPES, DUCTS, FREE-STREAM)
FUNCTION
- MEASURES FLUID MASS FLOW OVER A WIDE RANGE (using different approaches)
