Regarding transmitter spare parts
Thread Content
The installation is of large scale, with a large number of pressure and differential pressure transmitters, as well as various models. How should spare parts be considered in such a situation? There are also these transmitters; if they have the same model, they can actually be replaced even if their measurement ranges differ
For normal operation, a measurement value between 1/3 and 2/3 should be sufficient; there are no special requirements regarding other pressure media or similar factors
A large range can replace a small range, but a small range cannot replace a large range
It is best to choose the same model and type to avoid errors
First, one should consider whether the production environments are the same, such as having the same range, but also whether they are resistant to acids and alkalis. Moreover, when submitting spare parts, you need to consider the likelihood of those parts being used. For example, the pressure transducer in the circulating water pipeline can, if nothing goes wrong, last for over a decade. Do you decide whether to report the spare parts or not? ? Today’s voltage transformers are quite durable; they do not experience excessive pressure (above the designed range), mechanical damage, or damage to the diaphragm boxes caused by inadequate insulation in winter. Actually, there is no need to prepare spare parts. You also need to consider production requirements; for example, in the case of critical interlock instruments, it is necessary to resolve any issues as soon as possible. You can’t wait for the procurement department to buy it for you, right? For the rest, those with less stringent production requirements can function just fine without spare parts.
Thank you for your reply; you have thought very comprehensively. I’ve learned a lot!
