Earlier this week, I took a call from a customer having problems with his pressure transmitter. He’d figured out that his last transmitter, installed in an area with nearly continuous wash-downs, had failed because of water intrusion. The bigger problem was that it wasn’t coming from a loose cover, a conduit pipe, or a leaky conduit connection. In his case, the water came into the transmitter through a vent hole and messed up the measurement cell electronics.
So he asked me to recommend a 3000 PSI transmitter that could survive the washdown conditions.
A customer needed to re-range a Siemens SITRANS P DS III transmitter without applying pressure. He’d read my earlier blog post about using the pushbuttons to program the DS III (Pressure Transmitter Pushbuttons to the Rescue!), and where to find the Z-fold instruction sheet.
All was going to plan, until he started looking for the settings for lower range value (LRV) and upper range value (URV). And then, in an all-too-familiar scenario, he hit a roadblock. The instructions don’t actually mention URV and LRV, the terms he’s familiar with, by name or acronym. So what’s a guy to do?
