Metrological Practicum

Measurement of efficiency of differnt type of electric bulbs

• Measure Current/Voltage/Temperature/Ligth of Regular BULB, Chalogene BULB, "Cheap" and "Expensive" energy efficient bulb.

• Themographic analyses of electronic board deffects and board efficiency of cooling

Osmotic Pressure measurement

• With differential presure sensor measure the establishmet of osmotic equilibrium with different concentrations.

• Calibration of a force sensors

• Use an electronic balance to callibrate a piezo force sensor.

Measuring of Impedance of a Cable

• Measuring of Impedance of a coaxial cable up to 20MHz

Investigation of the behaviour of Peltier Based thermostate

• Using a peltier based thermostate to calibrate the law and position of used thermocouples for feedback contol with defined behaviour against ambient temperatures.

Collection of environmental data

• - P, T, Humidity, Measure relative humidity as function of temperature in a camera with heating.

Calibration of pH electrod and verification of it's linearity

• Using a set of Buffer Solutions with changing pH callibrate a stadard electrode and find the conversion coefficients pH/mV

Measuring of torque of servo motor / linear servo actuator

• The purpose is to verify efficiencie of a servo motor by analysing the current consumption and input voltage with different loads.

Measuring magnetic field around a cable

Calibration of vibration sensor

• Use of a vibration sensor as indicator for problems in industrial environment needs a calibration of it's sensibility. The proposed exercise has as purpose to identify a curve actual acceleration / sensibility of the sensor. The measurement involvs a set-up for vibration acceleraton sensor and vibration sensor.

Distance measurement

• Using phitgets distance sensor, identify the distance to an object. Verify the precision of the sensor by comparing the actual distance.

• High Temperature measurement - thermocouple and pirometer
