What is the head installation of temperature transmitter ? And its benefits

Terrate Installation Temperature Transmitter Receive signals from resistor temperature detectors (RTD) or thermocouple (TC), and Convert the measured temperature signal to 4 to 20 mA equivalent signals of the 2 -line circuit.

The head installation transmitter is installed in the connector of the sensor, so the size of the transmitter is very compact. In addition, because the transmitter is installed on the head of the sensor, the wiring is the least.

The traditional transmitter is installed at places far away from the sensor and requires additional preventive measures, such as lead compensation to minimize the measurement error. It also needs to generate an additional cable . If the sensor is a thermocouple type, the additional thermocouple compensation is required cable .

However, in the case of the head installation of the transmitter, the sensor does not need to be compensated, and the transmitter is installed in the same shell. Therefore, the measurement accuracy of the head installation transmitter is much higher than the traditional 2 or 4 -line temperature transmitter.

If the header installation transmitter is used for thermocouple sensor , no thermocouple compensation cable is required.

The head installation transmitter is a general temperature transmitter. Compared with the traditional temperature transmitter, it has many advantages. The head temperature transmitter has a HART communication protocol, which can be remotely programmed for the transmitter parameters such as temperature range, temperature sensor type.

The significant feature of the head installation of the temperature transmitter is as follows.

1. It accepts PT-100 input and type J/K/T/E/R/S/B/N thermocouple.
2. Users can configure the transmitter with PC software
3. Hart protocol for various input signals.
4. It has current and light isolation, so the signal -to -noise ratio is higher, and the problem of the ring road is eliminated.
5. It has non -easy -to -lose sex memory with data records
6. It has internal temperature sensors for active temperature compensation

The advantages of the head installation temperature transmitter
1. As the cable length from the sensor to the transmitter is shortened, the measurement accuracy is higher.
2. Use thermocouple without compensation cable
3. Easily replace the sensor and transmitter.
4. Easily programmed various input signals
5. Built -in Cold end compensation
6. Low signal -to -noise ratio
7. Reduce wiring
8. Remote programming and calibration
9. Low cost
