EJA510A And EJA530A Absolute And Gauge Pressure Transmitters Good Price
May 09, 2016

Yokogawa EJA510A and EJA530A Absolute and Gauge Pressure Transmitters good price 


Basic Information :

The absolute and gauge pressure transmitter model EJA510A and EJA530A can be used to measure

liquid, gas, or steam pressure. Both output a 4 to 20

mA DC signal corresponding to the measured pressure, and also feature remote setup and monitoring

through communications with the BRAIN™ terminal and CENTUM CS™ or µXL™ or HART® 275 host.


Routine Maintenance

1, check the installation hole size: If the size of the mounting hole is inappropriate, sensors during installation, the threaded portion is very susceptible to wear. This will not only affect the sealing performance of the device, and the pressure sensor is not functioning well, and may even produce a security risk. Only appropriate mounting holes to be able to avoid wear and tear thread (thread industry standard 1 / 2-20 UNF 2B), can usually gauge mounting holes on the mounting holes tested to make appropriate adjustments.


2, to maintain the mounting hole clean: clean mounting holes and prevent clogging of the melt to ensure the normal operation of the equipment is very important. Before the extruder to be cleaned, all pressure sensors from the barrel should be removed to avoid damage. When removing the sensor, the melt may flow into the mounting hole and hardened, if these residual melt is not removed, when the sensor is installed at the top again, it may cause damage. Cleaning Kit to make these melt residue removal. However, it is possible to repeat the cleaning process of the sensor mounting hole deeper damage caused. If this happens, we should take measures to raise the position of the sensor in the installation hole.


3, select the appropriate location: When the installation position of the pressure sensor is too close to the upper reaches of the production line, unmelted material may be worn on top of the sensor; if the sensor is mounted on the rear too far position between the sensor and the screw stroke may stagnation region generates molten material, where the melt may produce degradation, the pressure signal may also be transmitted distortion; if too deep barrel sensor, it is possible to touch the screw during rotation of the sensor to the top cause failure. In general, the sensors can be located on the screen in front of the barrel, before and after the melt pump or mold.


4. Carefully clean; before using a wire brush or special compound extruder barrel cleaning, all sensors should be removed. Because the two cleaning methods are likely to cause vibration sensor membrane damage. When the barrel is heated, the sensor should also be removed and no wear using a soft cloth to wipe the top, while the sensor holes also need to clean drill guide sleeve and clean.
