Without output (1) transmitter output temperature transmitter, check to see if the transmitter power after the; Take power supply polarity (2) the correct measurement transducer power supply, if there is a 24 v dc voltage; Must ensure that the transmitter power supply voltage 12 v (or The transmitter power input voltage of 12 v or higher) 。 If there is no power supply, should check whether the circuit disconnection, whether testing instrument selection error ( Input impedance should be 250 or less Ω) ; And so on. (3) if it is integrated with a header, check whether the header is damaged, Header in the first two wire short circuit, if the normal after short circuit, the header is damaged) ; Damage to the meter must in a separate header, (4) in series with the ammeter 24 v power supply circuit, check whether the current is normal; If normal shows normal temperature transmitter, should check other instrument in the circuit is normal. 1 blatantly transmitter output precision, transmitter power supply is normal, if less than 12 VDC, should check whether there is a big load in the circuit, transmitter, the input impedance of the load should comply with RL (or less - transmitter power supply voltage 12V) /( 0. 02A) Ω 2, ever for integrated debugging integration debugging 3, thermal resistance ( Or thermocouple) With the shell insulation whether meet the requirements such as insulation, blatantly is the insulation of the corresponding processing.
