Burner Management System (BMS) automatically initiate a safe operating or shutdown sequence to prevent an explosion from occurring inside furnace.
This post covers the PLC important questions and answers which are discussed in an interview for automation engineer or PLC
The Capacitive pressure sensor operates on the principle that, if the sensing diaphragm between two capacitor plates is deformed by
Ability to simultaneously measure 3 process variables (mass flow rate, temperature, and density) makes Coriolis flowmeter a versatile instrument indeed.
In electrical signalling an analog current loop is used where a device must be monitored or controlled remotely over a
Every instrument has at least one input and at least one output. For instruments responding linearly, the correspondence between input
4-20 mA instrumentation and controls usually support a signal range slightly below 4 mA and above 20 mA. For transmitters,
The term “loop” can refer to the entire “control loop” from primary element (sensor) through the transmitter, and controller, to
