Pt25 - Pt1000 principle of transducer is introduced

Used for Pt25 - The transmitter Pt1000

the output of the transmitter is the thermocouple sensor signals into a can be detected controller ( Or convert the non-electricity thermocouple sensor input into electrical signals and zoom to signal for distance measurement and control) The converter. Thermocouple sensor and transmitter together constitute the monitoring signal source of automatic control. Different quantities require different thermocouple 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 various physical quantities from thermocouple sensor, 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 thermocouple sensors to 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.
