Conceptual Difference Between Temperature Transmitter and Temperature Sensor
- differential temperature transmitterand temperature sensor
The temperature sensor is a general term for devices that can sense a prescribed measurement and convert it into a usable output signal according to a certain rule. When the output of the sensor is a specified standard signal, it is called a temperature transmitter.
Temperature transmitter (or intrinsically safe thermocouple transmitter) is an instrument that converts non-standard electrical signals into standard electrical signals, while sensors are devices that convert physical signals into electrical signals. In the past, physical signals were often used, but now other signals are also available. The primary instrument refers to the field measuring instrument or the base control meter, and the secondary instrument refers to the instrument that uses the primary meter signal to complete other functions, such as control, display and other functions.
The temperature sensor converts non-electrical physical quantities such as temperature, pressure, liquid level, material, gas characteristics into electrical signals or sends physical quantities such as pressure, liquid level directly to a head mounted or din rail mounted temperature transmitter.
The temperature transmitter is a signal source that amplifies the weak electrical signal collected by the sensor to transfer or start the control element, or converts the non-electricity input from the sensor into an electrical signal and amplifies it for remote measurement and control. The temperature transmitter by CHENZHU, a reliable company in safety and automation system, can also transform the analog quantity into the digital quantity according to the need. The temperature sensor and temperature transmitter together constitute a monitoring signal source for automatic control. Different physical quantities require different temperature sensors and corresponding temperature transmitters.
There is also a temperature transmitter that does not convert physical quantities into electrical signals, such as a "differential pressure transmitter" of a boiler water level gauge, which sends the lower water and upper steam condensate in the liquid level sensor to the instrument pipe on both sides of the bellows of the temperature transmitter, and the mechanical amplifying device is driven by the differential pressure on both sides of the bellows to indicate the water level with a pointer.
