Transducer Characteristics & Applications
LDR AS OPTICAL SENSOR
Objectives of this experiment:
In this trainer you will study that LDR resistance changes in proportion to light intensity. This causes a corresponding change in the voltage spanider output Vout is given by
Built in regulated power supply: +(0-16)VDC/300mA
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
Weight: 500gms
CLOSED LOOP MOTOR SPEED CONTROL
Objectives of this experiment:
To study the basic operation of closed loop control systems. Here the controlled variable is measured and fed back to the controller. The Controller then compares the measured value to the desired set point and generates a difference or error signal E=SP-M.
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
Weight: 500gms
HALL EFFECT CHARACTERISTICS
Objectives of this experiment:
In this trainer as Rs name implies HALL EFFECT device operates on 'HALL EFFECT' principles. HALL EFFECT occurs as current flows through a semi-conductor material that is under the influence of a magnetic field.
Built in regulated power supply: +(0-16)VDC/300mA
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
Weight: 500gms
LVDT CHARACTERISTICS
Objectives of this experiment:
To study the LVDT characteristics. The built in 4KHz oscillator generates sine wave. The LVDT produces a difference when we apply Force to it and h is rectified.
Built in regulated power supply: +12V/300mA, -12V/300mA.
OPEN LOOP MOTOR SPEED CONTROL
To study the basic operation of open loop control systems and to study the concept of controller and a control element, set point and dynamic process variable.
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
Weight: 500gms
THERMOCOUPLE CHARACTERISTICS
1.To study the characteristic of transducer
2.To observe the change in output voltage with charge in temp increases.
TRANSISTOR AS TEMPERATURE SENSOR
Objectives of this experiment:
In this trainer standard general purpose transistor can be used as a temperature sensor. The circuit output voltage Vo is proportional to temperature, since the of the transistor changes with temperature.
Built in regulated: + 9V/300mA
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
Weight: 500gms
