You’ve got a new 4-20mA pressure transmitter in hand and you need to wire it correctly the first time — without frying the board, starving the loop of voltage, or spending three hours debugging why the PLC reads zero. Here’s the short version before we get into the diagrams: in about 90% of industrial pressure-transmitter…
Absolute pressure vs gauge pressure explained by a 35-year refinery engineer — the 95/5 decision rule, the sealed-gauge trap, altitude drift for 5 US sites, and how to pick the right HMK transmitter.
Choose the right pressure sensor for high temperature service from +250°F to +2192°F. 4 methods compared with real specs and custom options from HMK-TECH.
Stop confusing pressure sensor, transducer, and transmitter. Use our 3-axis framework — distance, frequency, power — plus 3 real project cases from Europe, Singapore and the US to choose the right one in 30 seconds.
Two-stage framework for industrial temperature sensors: pick the sensing element first, then the assembly.
