Users in the purchase back to the pressure transmitter, did not use a long time on the damage, which has a direct relationship with the pressure transmitter does not have a direct relationship with the correct maintenance and maintenance. General pressure transmitter warranty is only one year, a little longer warranty two years. Few pressure transmitters warranty time for three years. We want to pressure transmitter long-term normal use, it is indispensable to daily maintenance and maintenance. Pressure transmitter of the correct maintenance and maintenance methods: First, moisture and humidity. A lot of pressure transmitter damage is caused by water. This requires us to ensure that when wiring the cable through the waterproof connector or winding tube and tighten. Sealing nut, this will prevent moisture and rain through the cable connector deep into the pressure transmitter subject inside. Second, anti-interference. Many signals will affect the stability of the pressure transmitter signal, surge, pulse group or electrostatic discharge of electricity will cause pressure transmitter burned or damaged, effective clear interference signal is essential. At the same time, the pressure transmitter must be effectively grounded, which is very important. Third, lightning protection. If the transmitter is installed in the poor site will encounter lightning or overpressure and other dangerous damage, it is recommended that the user in the distribution box or power supply and pressure transmitter between lightning and overvoltage protection. Fourth, anti-temperature. When the pressure transmitter is used to measure steam or other high-temperature media, pay attention not to let the medium temperature exceeds the operating temperature limit of the transmitter. If necessary, the need to install cooling devices. Fifth, keep the installation hole clean. Keep the mounting holes clean and prevent media clogging to ensure the normal operation of the equipment is very important. In the removal of the pressure transmitter, the measured medium may flow into the mounting holes and hardening, if these residual media is not removed, when the pressure transmitter is installed again may cause damage to its top.
