A differential pressure transmitter measures the difference between two pressures and converts it into a standard electrical signal. Here is how the sensor works, and how one instrument can measure flow, level and filter condition.
Selecting a pressure transmitter comes down to seven parameters: range, accuracy, output signal, process connection, medium temperature, hazardous area rating and housing protection. Get these right and the instrument will run for years.
Two habits quietly destroy variable frequency drives: cutting input power every time the machine stops, and switching contactors on the drive output. Here is why both damage equipment, and what to do instead.
A PLC control panel packages a programmable logic controller with circuit protection, power supplies, relays and terminals into one engineered cabinet. Here is what goes inside, where these panels are used, and the operating conditions they need.
