Pt25 - Pt1000 principle of transducer is introduced1

Used for Pt25 - Pt1000 transmitter

the output of the transmitter is the sensor signals into a can be detected controller ( Or will the sensor input non-electricity converted to electrical signals and zoom to signal for distance measurement and control) The converter. Sensor and transmitter together constitute the monitoring signal source of automatic control. Different physical quantities need different sensors and the corresponding transmitter. Many different kinds of transmitter, used in industrial control instrument mainly have the transmitter temperature transmitter, pressure transmitter, flow transmitter, current transducer, voltage transducer, and so on.

for Pt25 - Pt1000 transmitter principle of

the so-called 'change', refers to the physical quantities, from the various sensors to turn into an electrical signal. Such as: use of thermocouple, temperature into potential; Use of current transformer, large current is converted to a small current. Due to the electrical signals the easiest way to deal with, so, the modern transducer, are the various physical signal into electrical signal. Therefore, we say that the transmitter, usually becomes 'electricity'.

the so-called 'send', refers to the various has become the electrical signals, in order to facilitate other instrument or control unit to receive and transmit, again through the electronic circuit, the sensor to the electrical signals, unification ( For example, 4 - 20MA) 。 The method is implemented by multiple operational amplifier. This kind of 'change' + 'send', and formed the modern the most commonly used transmitter.
