Group of devices that take control of a logic process, offering a real-time reading of its variables.
They are fundamental in order to obtain the best results from a productive unit optimizing resources and producing competitively, from energy savings and absolute control of the parameters required for each project.

Instrumentation types

Instrumentation types by function

→ Primary elements: They are in contact with the fluid: pressure gauges, thermometers, pressure transmitters, orifice plates, etc.
→ Transmitters: capture the process variable through a primary element and transmit it remotely using a digital or analog signal.
→ Local indicators: capture the process variable and display it on a scale in a visible way: manometers, rotameters, thermometers. They can be connected to a transmitter.
→ Switches: capture the process signal and, for a set value, act on a switch, moving from the rest to the activated state: pressure switches, thermostats, level switches, flow switches, etc.
→ Converters: they receive the signal from an instrument and change it to another type of signal: from pneumatic to electronic signal, etc.
→ Final control elements: they receive a signal from a controller and modifies the flow: control valves, frequency inverter, etc.

Instrumentation types by process variable

→ Pressure measurement or local pressure indicators
→ Pressure transmitters: capacitive, resistive, piezoelectric
→ Flow measurement: positive displacement meters, mass meters, orifice plates, nozzles, etc.
→ Temperature: local temperature indicator, thermocouples, thermoresistance, thermostats
→ Level: Level indicators, level transmitters, etc.
→ Analysis measures: analyzers of emissions and atmospheric conditions
→ Final control elements: valves
