Most transmitters are available with and without display, and the transmitter with display can display the measured value of the measured medium in real time at the use site, which is convenient for observation and numerical detection. The type of transmitter display will vary slightly in terms of form factor, supply voltage, overall weight, and degree of protection. In the case of pressure transmitters, pressure transmitters with display are longer and wider in form factor than pressure transmitters without display. The supply voltage of the pressure transmitter with display is 15~36VDC, and the supply voltage of the pressure transmitter without display is 12~36VDC. In terms of weight, the pressure transmitter with display is about 80g heavier than the pressure transmitter without display. Pressure transmitters with display have a lower degree of protection than pressure transmitters without display. During use in the field, the user may encounter a situation where the transmitter does not display due to improper operation. At this time, we need to check them one by one. First, check whether the power supply of the transmitter is reversed, and whether the positive and negative poles of the transmitter are connected correctly. Second, whether the power supply of the transmitter is used correctly, the power supply voltage of the transmitter with display is generally 15~36VDC. Third, check whether the transmitter display meter is damaged, the two wires of the meter head will be shown to be short-circuited, if the short circuit is normal, it means that the transmitter meter head is damaged. Fourth, check whether there is a problem with the transmitter, and connect the ammeter into the 24V power supply circuit to check whether the current is normal. If it is normal, it means that the transmitter is normal, and the other instruments in the circuit should be checked for normal. It is necessary to have a careful troubleshooting of the transmitter before it can be used and connected to the device.
