HART Double Channel Din Rail Temperature Transmitter Electrical installation

Transmitter wiring and power supply

All the power needed by the transmitter is provided by a signal line. Use regular copper wire of sufficient size to ensure that the voltage between the supply terminals of the transmitter is not less than 11VDC.

If the sensor is installed in a high voltage environment and fails or is installed incorrectly, there may be dangerous voltages on the sensor leads and transmitter terminals. Extreme care should be taken when in contact with wires and underends.

Note: do not apply high voltage to the transmitter terminal (e.g. ac line voltage). Excessive voltage may damage equipment.

HART Double Channel Din Rail Temperature Transmitter Sensor Connection

Thermocouple or millivolt input

The thermocouple can be connected directly to the transmitter.If the transmitter is mounted at a distance from the sensor, use the appropriate thermocouple extension wire.Use copper wire to complete millivolt input connection.For longer wiring, shield lines should be used.

Thermal resistance or ohmic input

The transmitter can accept a variety of thermal resistance configurations, including 2-wire, 3-wire or 4-wire configurations.If the connection distance is long, a third or fourth lead should be connected.

Influence of sensor lead resistance - thermal resistance input

When using 4-wire thermal resistance, the influence of lead resistance can be eliminated without affecting the accuracy.However, the 3-wire sensor cannot completely eliminate the lead resistance error, because it is necessary to eat the resistance imbalance between the leads.The use of the same wire on all three leads will allow for the greatest accuracy in the way the 3-wire thermal resistance is mounted.The 2-wire sensor has the biggest error, because it directly adds the lead resistance to the sensor resistance. At this time, the function of "2-wire zero calibration" is needed to eliminate the error caused by the installation method of 2-wire thermal resistance.
