What is the Difference between Static and Dynamic Torque transducers?
Using the strain gauge principle, a special torsion measuring strain gauge is pasted on a special elastic shaft to form a Wheatstone bridge.
They are similar in some aspects:
- Both ends have output shafts
- DC voltage supply ±12V/24V
- Frequency, current, and voltage signal output
- Form factor can be customized by the user.
Differences between static and dynamic torque transducers:
Dynamic torque transducers are larger than static torque transducers for the same range.
Static torque transducers rotate with the power source. When the power source rotates the static sensor, the housing rotates with it.
During measurement, the angle of rotation cannot exceed 360°. Dynamic torque sensors, on the other hand, rotate with the power source and have no angle limitation.
Dynamic torque sensors can measure either the rotational speed or the angle of rotation. Since static torque sensors cannot rotate more than 360° without this feature, they cannot measure RPM.
What is the Difference between a Sensor and a Transducer?
A transducer is a device. It can be subjected to a specified measurement and converted into a usable output signal according to a certain pattern. Sensors usually consist of a sensitive element and a transducer element, such as a pressure sensor.
When the output of the sensor is a prescribed standard signal, it is called a transducer. Transducers are instruments that convert non-standard electrical signals into standard electrical signals. Such as pressure transducers.
Sensors are devices. It converts physical signals into electrical signals. And in the past, they often spoke of physical signals, but now other signals are also available. Primary instrumentation refers to the field measurement instrument or base control table. Secondary instrumentation refers to the use of primary table signals to complete other functions, such as control, display and other functions of the instrument.
Sensors and transducers are originally concepts of thermal instrumentation. Sensors are non-electrical physical quantities. such as temperature, pressure, level, material, gas characteristics, etc., into electrical signals or physical quantities.
The transducer is the weak electrical signal collected by the sensor to amplify in order to transfer or start the control element. Or the sensor inputs into an electrical signal at the same time. sensor amplified for remote measurement and control of the signal source.
According to the need can also be converted from analog to digital. Sensors and transducers together constitute the monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transducers.
There is also a transducer that is not a physical quantity into an electrical signal. Such as a boiler water level meter “differential pressure transducer”. Of course, there are also electrical analog quantity into digital quantity can also be called a transducer.
Sino-Inst has a wide range of sensors and transducers:
level transducers, pressure transducers, flow transducers and so on.
