Pressure Measurement

A pressure transmitter converts process pressure into a standard electrical signal. This guide walks through the parameters that decide a correct selection: pressure type, range, output, wetted materials, process connection, temperature, accuracy and hazardous-area needs, and what to send for a quotation.

Pressure Measurement

The three terms are often used interchangeably but describe different levels of signal processing. A sensor is the sensing element, a transducer adds basic conversion to a voltage or similar output, and a transmitter delivers a conditioned industrial signal such as 4–20 mA. This guide compares them.

Level Measurement

A level switch gives a point alarm or control signal when liquid or solids reach a set height. This guide compares float, conductive, capacitive, vibrating fork and ultrasonic technologies, and covers media, mounting, contact rating and fail-safe logic so you can narrow your selection.

Flow Measurement

Flow meters differ in principle, and each suits particular fluids and pipe conditions. This guide compares electromagnetic, ultrasonic, turbine, vortex, Coriolis, variable-area and positive displacement meters, and lists the process data you should gather before choosing between them, such as fluid, range and line size.

Valves

A solenoid valve opens or closes a line when its coil is energised. Correct selection covers media, flow capacity, pressure differential, normally closed or open action, direct or pilot operation, body and seal materials, coil voltage and area classification. This guide explains each.

Compressed Air Treatment

Compressed air carries water, oil aerosol, particles and vapour. Pre, fine, micro and carbon filters each remove a different contaminant, so they are fitted in sequence with a dryer. This guide explains the order, what each stage does, and the data to give when specifying filters.
