Instrumentation & Control
Measurement devices and accessories specified by process conditions, range, connection and signal. Brand headquarters do not establish manufacturing origin.
Pressure gauges and transmitters
Pressure gauges provide local indication, while pressure transmitters convert a pressure measurement into a signal for monitoring or control. Gauge, absolute and differential pressure describe different measurement references that must be matched to the application.
Process lines, vessels, filters and utility networks use pressure measurement for operating information and control. Differential pressure can also support level or flow measurement in an engineered arrangement.
Range, overload capability, connection, wetted materials and output distinguish common configurations. Diaphragm seals or other process interfaces may be needed for particular fluids.
Temperature sensors and thermowells
Temperature sensors measure process temperature using elements such as resistance temperature detectors or thermocouples. A thermowell is a protective process connection surrounding a compatible sensor; its material and geometry are part of the mechanical design.
Piping, vessels, machinery and thermal systems use temperature measurements for monitoring and control. RTD, PT100 and thermocouple references identify different sensing arrangements.
Sensor type, insertion length, connection and signal interface must match the installation. Thermowell material, dimensions and the process conditions require separate mechanical review.
Radar and ultrasonic level instruments
Radar level instruments use electromagnetic signals, while ultrasonic instruments use sound to measure distance to a surface. Their suitability depends on the medium, vessel geometry and conditions along the measurement path.
Storage tanks, process vessels and selected open-channel applications use non-contact level measurement. Guided wave radar is another arrangement where the signal follows a probe.
Compare measuring range, product properties, nozzle geometry, pressure, temperature and output. Foam, vapors, obstructions and surface conditions can influence measurement performance.
Flow meters
Flow meters measure the movement of liquid or gas through a defined path. Different measuring principles respond to volume, mass or related physical properties, so the required measurement basis matters as much as line size.
Process control, utility accounting and transfer measurement use flow meters. Coriolis, magnetic, ultrasonic, turbine and differential-pressure methods address different fluid and installation conditions.
Fluid composition, conductivity where relevant, flow range, available straight runs and required uncertainty influence selection. Specify the output and any calibration or approval requirements.
Analyzers and sample systems
Process analyzers measure composition or quality characteristics of a process stream. Sample systems transport and condition a representative sample so the analyzer receives it within the instrument's specified operating limits.
Gas quality, combustion monitoring, water chemistry and product control use analyzers. The measurement objective determines the sampling arrangement and required response time.
Specify measured components, ranges, sample conditions and utilities. Sampling probes, conditioning, calibration media and disposal arrangements should be identified within the package boundaries.
Switches, indicators and local gauges
Switches provide a discrete response at a specified condition, while indicators and local gauges show a measured variable directly. These devices supplement or support electronic measurement and control systems.
Level indication, pressure alarms, flow confirmation and temperature monitoring are common applications. The device must match the process connection and expected environmental exposure.
Switch points, contacts, measuring range and local display arrangement distinguish options. Magnetic level gauges, sight glasses and variable-area flow indicators require different installation details.
Vibration and machinery monitoring
Machinery monitoring systems collect signals that describe machine condition. Vibration sensors, proximity probes and related monitoring hardware provide information that can support fault assessment and maintenance decisions when interpreted in the machine context.
Pumps, compressors, turbines and motors use condition monitoring. The measurement locations and machine dynamics determine which signals are useful.
Sensor range, mounting, signal conditioning and compatibility with the installed monitoring platform are essential. A hardware supply scope differs from diagnostic analysis or monitoring services.
Instrument calibration equipment
Instrument calibration equipment supplies reference signals or measurements used to compare an instrument's response against a known basis. The required uncertainty, range and traceability determine whether a reference is appropriate for the measurement task.
Pressure calibrators, dry-block temperature sources and electrical calibrators support field maintenance and laboratory work. Deadweight testers provide another pressure-reference approach for specified applications.
Consider reference uncertainty, stability, portability, interfaces and calibration documentation. Accessories and adapters should match the instruments that will be tested.
